lead-free

Many electronics use solder as the “glue” to attach components to circuit boards. Whether lead-free or lead solder, the function is the same. Lead-free and lead solder do perform the same function. However, different products and applications will use different solder.

Why Do We Need Lead-Free Solder

When manufacturing specific products, they must use lead-free solder. This is due to new regulations by RoHS.  The main reason for the introduction of these regulations is the need to reduce lead in the landfills, mostly in Europe. However, American industries are now sharing these views.

With the increase of popularity of electronics in every home and businesses the need to reduce lead is becoming more important. On circuit boards, solder attaches components and wires, as previously stated. Solder is also a part of manufacturing wire harnesses. Electrical devices wear out over time and therefore need to be disposed of.  There is an increased amount of lead being removed from landfills and other disposal areas by reducing the amount of lead solder within these electronics.

What Are the Uses of Lead Solder

Most hobby solderers still use lead solder for their projects. Due to these projects not being publicly or commercially used they don’t have strict regulations of RoHS to follow. Hobbyists will often choose lead solder for their projects because of its high melting point and therefore the decreased heat required. Also, with a higher melting point, the cooling time required for the solder is lower and can mean a decreased chance of cold solder joints. A cold solder joint can mean that there is not a good connection of the component to the circuit board. This bad connection can lead to a project failure.

Also, hobbyists do not use the amount of solder that commercial manufacturers do. The decreased use is the main reason why there are not as many regulations on hobby electronics. Due to this decreased use, there is also a decrease in the waste from the lead solder. A hobbyist will not use the amount of solder that a commercial manufacturer will in a year’s time.

Capicitors

Capacitors

Capacitors

There are multiple options for the material of capacitors. There are also different purposes for each material. The materials range from ceramic to Teflon. Although the materials are all different from each other they all have one thing in common. All of the materials are non-conductive.

Depending on the capacitor some are better for high frequency. Meanwhile, others are better suited for higher voltages. There are capacitors in the smallest electronics like calculators. Also, there are capacitors in large electronics like the NASA space shuttle.

Capacitors work like batteries in a circuit. Once a capacitor is charged it will have the same voltage as the battery that initially charged it. However, there is a difference between a capacitor and a battery. A capacitor can discharge its energy in a very short amount of time. Whereas a battery takes a longer amount of time to discharge its energy. Farads or even micro-farads are the units of the amount of energy a capacitor will store.

Here is an excellent video about capacitors from our friends at Techquickie:

Integrated Circuits (ICs)

Integrated Circuits

An IC can do the job of many different components. Due to its small size, it is surprising the amount of technology that it holds. The idea behind an IC is to take a complicated circuit with all of its components and connections and make it very small. Therefore, creating a single component that is small enough to fit into smaller electronics.

There is a large process when creating such a small part that contains so many smaller components. An integrated circuit, commonly referred to as an IC, is a microscopic array of electronic circuits and components. These circuits and components have been diffused or implanted onto the surface of a single crystal, or chip, of semiconducting material such as silicon.

Due to its small size, there can be a lot of challenges with an IC. The main issue when working with such small circuitry is it is very easy for small dust particles to impair an ICs function. Therefore, workers take extra precautions when assembling an IC. Some of these precautions include clean labs. These clean labs have special filters for the air to decrease the dust that could damage the IC. Also, anyone working on these components has to wear special protective clothing and enter the labs through airlocks.

switches

Switches

Switches are components that have the ability to go between conducting electrical energy and not conducting energy. Therefore, Switches control the current flow on a circuit board. This control is easier than having to go in by hand and cut connections within the circuit. These components are important to a circuit board that requires control of current flow.

There are also many different types of switches. Some of the types of switches include toggle, joystick, and pushbutton switches. Each of these types performs the same basic function of conducting and not conducting energy easily. However, each type of switch is structurally different which are described below.

Toggle

toggle switchtoggle switches

A toggle switch contains an angled lever that goes in one or more directions. A light switch is a common type of toggle. Due to the way that a light switch holds its on or off position the circuit is either open or closed. There are also types of toggles that include a spring. This spring means that the lever will not stay stagnant in the switched position but will return back to a predetermined position.

Joystick

joystick switches

A joystick switch contains a lever much like the toggle switch. However, the joystick moves in multiple directions. This is unlike the toggle switch’s movement of singular direction. Most recognizable is the joystick on a claw machine. The freeness of directional movement makes it possible to control the claw in any direction required.

Push-button

green push button switchpush button switchespush me switch

A push-button switch is two position component. Just as the name would suggest a push-button switch works by pushing the button in and releasing it. There are also designs of push-button switches that when pushed in the button does not release until it is pulled out or pushed a second time. The most recognizable push-button are those on a television or sound system.

Our PCB Component series will continue on our blog.

Resistors, Diodes, and Transistors

Resistors, diodes, and transistors are integral parts of a functioning Printed Circuit Board. Without them, a PCB would not be able to perform its tasks. Each of these components has a specific function.

Resistors

Resistors Resistors    

Resistors are a part of a Printed Circuit Board. A resistor creates resistance in the flow of electricity. When calculating resistance the measurements are in ohms. An ohm is a standard for measuring electrical resistance.

Resistors have many different purposes. A resistor’s purpose includes the division of voltage. Resistors divide voltage when they are in series with each other. Another purpose of resistors is their way of generating heat. A resistor can generate heat by converting the electrical energy flowing through it to heat energy. The final purpose that we will describe is how resistors match and load circuits. Most of the output power is displaced as heat in the instance of a too low load resistance. However, if the load resistance is too high then the current will be too low to move energy to the load.

Here is an excellent video from ResistorGuide.com:

Diodes

   Diode         Diode

Diodes only allow current to flow in a single direction. Also, diodes have two electrodes. The anode and the cathode are the two electrodes within a diode. An anode allows current to flow from an outside circuit. Whereas a cathode allows current to flow out in a polarized device. A cathode is also metallic.

A diode only works properly if a cathode is negatively charged in respect to the anode at the specified voltage. Therefore, when a cathode is positively charged the diode does not work at all. This will also happen if the cathode has the same voltage as the anode. It also occurs when its negativity is less than that of the forward breakover voltage with respect to the anode. The direction of the cathode is very important to the diodes functionality.

Transistors

Transistor      Transistor

Transistors are three-terminal devices. This three-terminal device can regulate current or voltage flow while also acting as a switch for signals of the electronic variety. Semiconductors make up three layers of a transistor. Therefore, each of these layers can carry current. The material of a semiconductor is between that of a real conductor and an insulator. A transistor’s job is to amplify or switch electronic signals and electrical power and to regulate the current or voltage flow in a circuit and that is only possible due to the semiconductors.

Printed Circuit Boards

Printed Circuit Boards

The History of Printed Circuit Boards

A wood material patented by William H. Mason called Masonite made up Printed Circuit Boards. Masonite is a wood that has gone through pressure molding and steam treatment. Bakelite, an early type of plastic also made up some of the very first Printed Circuit Boards. Finally, cardboard even made up some of the original boards.

In order to rivet flat wires onto boards holes needed to be drilled. These riveted wires created the first primitive form of the traces we know today. Therefore, using rivets as the spaces for component placement.

In the beginning, Printed Circuit Boards were only one-sided. Due to the components going through the boards by way of the rivets, there was no way to have circuitry on both sides. Circuit boards made it possible to condense electronic components into one place rather than have wires running all through an electronic device.

Modern Day Printed Circuit Boards

After the initial design of the single-sided circuit board, there were new developments. These new developments were to drill holes in the boards and then plate those holes with copper. The result of this copper plating is that you can now use both sides of the board.

Much like the circuit boards of today, there was printing on the boards of the past. They were able to use a printing press to place the images of the drawing pattern onto a zinc plate with a copper foil and then transfer those images onto the boards. This was the early stages of the pattern transfers that we know today.

Early on in the circuit board development, they did not solder dip their boards. However, in modern designs, solder dipping or wave soldering is very common. By using solder circuit boards, manufacturers can ensure the connections between the components and boards.

Avoiding Grief and Pain When Using Your Soldering Iron

In a recent blog post, we discussed soldering safety tips. Our team brings over 100 years of experience with soldering circuit boards. Over the years, we have learned the best practices on how to efficiently and safely solder a variety of electrical products, particularly printed circuit boards. Through our vast experience, we have also gained a clear grasp on what NOT to do while holding a Soldering Iron.

10 Things NOT to Do While Holding a Soldering Iron

Below is a helpful list that may spare you lots of grief and pain when using a Soldering Iron:

  1. EYE SPY PAIN
    Something in your eye? Please put the soldering iron down first. Thankfully your safety goggles are in place for absentminded events such as this. Singed eyelashes will be the least of your problems without your safety glasses securely fastened.
  2. NEW NOSE RING 
    Scratching an itchy nose with a soldering iron in your hand is typically not a good idea. Unless you are eager to add that new nose ring that you have been putting off. If that is the case, then the soldering iron will cut right through the victimized or targeted area. Viola! A new hole available for your new nose ring.
  3. OUCH!
    Absolutely under no circumstance should you zip up you fly if you notice it is down. No adjustments, fixing, or any other engagement in that general area while holding a soldering iron. Results could be disastrous. Plus you will have an extremely difficult time trying to explain this accident to the emergency room staff.
  4. USE Q-TIPS INSTEAD
    Feel water floating in your ears from the early morning swim? This is not the time to clean out your ears. Set down your soldering iron and grab a few Q-tips.
  5. NO KNEE-SLAPPERS
    Tell everyone around you no jokes if you are one to slap your knee when laughing. Yelling, “Hey Johnny, that’s a knee-slapper” can turn painful real quick once the soldering iron hits your knee.
  6. SEE #1
    Soldering is not a time to apply mascara or eyeliner. Please refer to rule #1.
  7. WORSE THAN A ROOT CANAL
    If you suddenly feel a piece of popcorn stuck in your teeth from that movie you watched three nights ago, please do not try removing the kernel while soldering. A soldering iron is not a replacement for a toothpick and this could quite easily be more painful than a root canal without Novocain.
  8. NO SELFIES
    Holding or using your cell phone while soldering typically falls under the category of a “Bad Idea”. If you find it necessary to Facetime or Go Live on Facebook while soldering, please have someone else hold the phone to film your activities. You will be glad you played it safe.
  9. HOLY SMOKES BATMAN
    Please under no circumstance do you want to apply lipstick or Chap Stick while holding a soldering iron.  You may end up looking like the Joker from Batman….permanently.
  10. NO STRETCHING 
    Last but not least, if you are sitting next to someone while soldering, please keep them beyond arm’s length. Especially if you like to speak with your hands, point when making a point, flail your arms when emotional, stretch frequently or tend to smack people on the shoulder when speaking. All of the above can cost you a friendship real quick.

Soldering Iron

We had fun putting together this list even though burns and injuries are a very serious matter. Please use extreme care and caution when using a soldering iron. Hopefully, these tongue-in-cheek comments convey the message. We use the safest measures possible when soldering printed circuit boards at our facility. Falconer Electronics has proudly participated in the SHARP program since 2005 to proactively maintain a healthy and safe workplace.

History of Circuit Boards

The Beginning of the Twentieth Century

The History of Circuit Boards dates back to the beginning of the twentieth century. Albert Hanson, a German scientist, and inventor, first described the use of multiple layers of foil conductors laminated to an insulating board in 1903.

In 1927, Charles Ducas’s circuit method placed an electronic path directly onto an insulated surface. The wires were printed onto the board through a stencil, and the ink applied could conduct electricity. This process is an early version of electroplating.

Next came Paul Eisler. He invented the first printed circuit. This was in England in 1936 while working on a radio set. Eisler’s early PCBs were first used in small radio sets. They were intended to be used by the British and American military during World War II. However, the US military ended up incorporating PCBs into anti-aircraft shells. In 1947, the First double sided PCB’s with through-hole plating began production.

The Middle of the Twentieth Century

In the middle of the Twentieth century, the types of materials used for the board was shifting to different resins and other materials. However, there was a problem with these materials. Only one side could have the printing. Therefore, the wiring would be on one side, while the electrical components would be on the other.

In 1956, the U.S. Patent Office granted a patent to a small group of scientists representing the U.S. Army. The patent was for the “Process of Assembling Electrical Circuits”. The process involved drawing the wiring pattern and then photographing it onto a zinc plate. This plate was the first step in creating a printing plate for an offset printing press. By using this plate they could print the wire in acid resistant ink on the copper foil. Furthermore, the use of an acid solution would etch the copper foil. This was a giant leap forward. Therefore, in 1960, a multilayer PCB design began production.

The End of the Twentieth Century

In the 1970s, the circuitry and overall size of the boards got a lot smaller. Also, there was an increase in the use of hot air soldering methods. During the 1980s, Surface mount parts became the preferred option. This was over through-hole components. This led to further size reductions. All while maintaining the same level of functionality.

In the 1990s, the complexity of modern circuit boards continued to go up. However, the size of the boards and costs of materials continued to go down. Once developers were able to start using multi-layer circuit boards they were able to minimize the size. Also, they were able to incorporate combinations of rigid and flexible PCBs in a range of devices. 1995 was the beginning of the use of micro-via technology in PCB production. Which ushered in the era of HDI (High-Density Interconnect) PCB’s.

How often do we really think about the electric makeup of everyday objects? We use things every single day that contain printed circuit boards and we don’t realize it. We’ve collected a list of everyday objects that may surprise you by containing PCBs.

PCB is short for Printed Circuit Board. These boards are the object within electrical devices that connect all of the internal electrical components to each other. These boards contain electrical lines that conduct electricity, components, and solder. All of these things work together to make everyday items that we see and use run correctly.

5: PCBs in Digital Watches and Clocks

How many times a day do you check a clock or your watch to see the time? Think about the days that you look at a clock and think it must be lunch time only to discover it is only eight O’clock which is just five minutes after the last time you checked. On the days that you are checking your digital watch or clock multiple times do you think about what’s inside them to make them work? That watch you looked at at-least one hundred times today hoping it was lunch time has a tiny circuit board in it. The idea that inside a small sized watch is an entire circuit board with even smaller components is an incredible thought. With their smaller size, watches have even smaller components making them function the way that we have become accustomed to.

4: Washers and Dryers Using PCBs

If you didn’t have to wash your clothing by hand to have clean clothes for today you can thank a circuit board! Well, technically a few circuit boards because you used both a washer and dryer. Washers and Dryers are a convenience that very near everyone uses. They make our lives easier and take the hard work out of scrubbing those tough stains. Grandparents everywhere are forgetting the days of hand washing and having to scrub stains without fancy stain removers that we know and love. None of this would be possible without PCBs.  

3:  Fans, AC units, and Heaters 

                                        Related image  

Fans, AC units, and Heaters are very helpful with changing seasons. Who hasn’t gone to the movies on a hot summer day just to suck up some free air conditioning? Think of how different life would be without heaters in our homes and office. Furthermore, who hasn’t been grateful to hear the heating system kick on when temperatures drop to single digits.  No matter the temperature these helpful units of air adjustment keep us comfortable all year round and all because they have PCBs. 

2: Stereos

No one goes through an entire day without listening to music on some type of device. This includes home stereo systems, iPods, or CD players. Every day we set the tone for our mood by what we hear on the radio or what we plug our headphones into. All of these devices wouldn’t be possible if it weren’t for PCBs. We would all be living in a very quiet place if it weren’t for the small circuit boards. These boards make them function the way we need them to.        

1:  Electronic Kid Toys

                                                  

Kids love toys that make noise, the louder the better. Parents around the world have had to learn to tolerate listening to the same three versions of the wheels on the bus. The newer kids movies and shows circulate around songs. There is more chance of parents “misplacing” a child’s toy just to get some peace and quiet. These delightful moments of listening to the same song over and over again wouldn’t be possible without a PCB.

Soldering Safety Tips

Hand soldering printed circuit boards takes tremendous skill, patience, and expertise. As we discussed in a previous blog post, our team at Falconer Electronics has over 100 years of soldering printed circuit board experience. Below includes a list of Soldering Safety Tips that helps keep our staff safe. 

Soldering Safety Tips

14 Helpful Soldering Safety Tips

  1. First, if the soldering iron happens to slip out of your hand, PLEASE DO NOT GRAB IT! The soldering iron is extremely HOT. Let it fall, keep your cool and pick it up by the handle. Wearing gloves or having a dry cloth nearby will come in handy (yes, the pun was intended).  
     
  2.  Solder runs. It can seep through a hole in a printed circuit board. Ouch! After doing that a time or two, you will wisely consider wearing gloves. Using tweezers to hold the wire works great as well.
     
  3. Always return the soldering iron to the stand when not in use.  
     
  4. Safety Glasses, Safety Glasses, Safety Glasses. By the way, did we mention Safety Glasses? Safety Glasses probably serve as the most important tool and resource that you will use when soldering.
     
  5. Keep the cleaning sponge wet.
     
  6. Wash hands thoroughly when finished soldering. Especially if you are grabbing a meal afterward. Lingering solder on your fingers typically does not add value to the tastiness of a meal.
     
  7. Wear long sleeves and gloves. Our team has observed that solder plays “Dodgeball”. Solder likes to toss or launch little specs of heat at you. Unfortunately there is little time to “dodge” these bundles of joy. Protect your skin as much as possible. By the way, did we mention to make sure you are wearing safety glasses?
     
  8. Keep the work station clean and free of clutter. Cords from the soldering iron can easily become entangled with other objects on your workstation. The soldering iron can quickly fall. As we mentioned, NEVER grab a falling soldering iron. An even worse result would be finding the soldering iron in your lap.
     
  9. Place ice or cold water on accidental solder burns immediately. For serious injuries seek medical assistance ASAP!
     
  10. Keep a fire extinguisher nearby. Also, make sure it is current and up to code.
     
  11. Extract Fumes! Preferably a ventilation system that vents out of the building. For home use or hobbyist, there are many options including fans with filter boxes. 
     
  12. Avoid dirt or particles when soldering.
     
  13. Keep soldering iron turned off and unplugged when not in use. 
     
  14. Never solder live circuits or wires. This could be an Electrifying experience!

SMD Stencil Printer

Soldering with SMD Stencil Printer

One particular piece of equipment that certainly elevated our game with soldering printed circuit boards this year: The Dual Squeegee SMD Stencil Printer from Mancorp

SMD Stencil Printer

 SMD Stencil Printer at Falconer Electronics

Easy and Efficient Soldering 

The main tip for soldering with a stencil printer: PULL! Simply pull the lever and sweep the solder across the board and Voila! It is easy, efficient, fast and furious. 

This SMD Stencil Printer fits our formula perfectly targeting prototyping and low-to-medium PCB production. 

The printer provides the necessary versatility and reliability that our customers expect. Especially since the printer handles individual boards all the way up to large panels, both single and double-sided. 

In addition, the ease of use and efficiency rocks! Pneumatically controlled dual floating squeegees provide constant and even pressure throughout the print stroke. This ensures consistency with each and every board which minimizes the risk of solder bridging as well as bleeding of the solder paste. 

The squeegee moves bi-directional (swings both ways) making it possible to print while pulling the lever forward and on the return. This greatly improves efficiency to cover all solder points. 

Upon the completion of the print (which literally takes a few seconds), the risk of solder paste being smeared is eliminated by the vertical lift lever. The stencil lifts upwards off of the PCB as the lid opens away from the printer. This ensures well-defined print edges. 

The SMD Stencil Printer is Fast and Furious

Like we said, fast and furious yet delicate and precise. (Did that last sentence even make sense?) Anyway, our team and customers love the improved efficiency gained by Soldering with the new SMD Stencil Printer.

Let’s reiterate, patience is paramount when soldering circuit boards. One of our seasoned veterans at Falconer Electronics likes to say, “Without patience, you can kill a circuit board.”

Soldering by hand takes a special skill when soldering wires or components.  Several FEI team members also state, “a healthy solder joint looks like a Hershey Kiss”.

Finally, when partnering with a custom manufacturer for soldering circuit boards, selecting a company that you can trust is essential. A manufacturer with a seasoned staff and decades of experience also lends tremendous value to your business. Our team welcomes the opportunity to work with you. As a bonus, we’ll throw in lots of Hersey Kisses!

Printed Circuit Board Safety

Printed Circuit Board Safety has been a serious concern as the industry has vastly grown and developed over the years. There are many safety issues when assembling and producing printed circuit boards. This is our last post for our series with commemorating May as Electrical Safety Month. In our previous posts on safety, we addressed OSHA as well as safety steps with wire harness assemblies and commercial outlet strips. This post will address printed circuit board safety. 

SHARP Program 

Safety at Falconer Electronics is an absolute top priority as shown with the company commitment to participating in the SHARP program. It can be extremely challenging for a small manufacturer to keep up with every new safety regulation. With constantly changing rules and regulations, Falconer Electronics has taken a proactive stand. The team at Falconer Electronics works closely with consulting firm Safety Compliance, Inc on OSHA compliance and workplace safety: (http://www.safetycomplianceusa.com/index.html).

Printed Circuit Board Safety 

Soldering printed circuit boards requires a special skill set. Our soldering team has combined experience that exceeds 100 years! They are an impressive group that produces high-quality circuit boards. Due to our commitment to safety, we have enjoyed over 12 straight years without a work injury or safety violation.

SHARP has also been very helpful with our soldering process. We have an extensive ventilation system disposing of fumes caused by the high heat of the mettle.

Secondly, our new circuit board pick and place machine offer many safety features that are extremely beneficial to our team. This machine places 3000 parts per hour. The machine comes equipped with a safety lid and switch. 

Another issue that we have seen in our shop is that of the safety glasses. Safety glasses are required on the floor of our factory due to the possibility of wire shavings or other material that are in and around that could cause eye damage. There have been situations where people have been clipping wire ends or leads and have had the piece fly off through the air. 

Circuit Board Safety Tips 

Below include a number of precautions with printed circuit board safety:

  1. Wearing safety goggles – Protective eyewear is essential (and mandatory)!
  2. Wearing gloves
  3. Handle solder diligently with care
  4. Clutter free workstations 
  5. Appropriate temperatures
  6. Utilize ventilation system
  7. Acceptable lighting
  8. Do not put cookies or food through reflow oven (just checking if you are reading this)
  9. Proper tools
  10. Check all connections
  11. Testing 
  12. Proper cleanup
