What is a Circuit Board?

circuit board

If you are new to the world of industrial electronics, you may be hearing the terms “circuit board” or “printed circuit board” come up quite often. Circuit boards are one of the most important inventions ever created. Keep reading to learn more about circuit boards and how they help industrial electronics function.

What is a Circuit Board?

Without getting too technical, a circuit board is a printed board that includes electrically conductive pathways that connects electronic components to one another. Circuit boards exist to connect all electronic components of a device in one compact space. Circuit boards also help protect the electronic components of a device by keeping them insulated. Circuit boards have many different layers, sometimes up to 30 or more, that provide power to a device. Circuit boards are the foundation of all electronic equipment. Everything electronic, from elevators to phones to printers, depends on circuit boards to function.

Why are Circuit Boards Helpful?

Prior to the invention of circuit boards, electronic machines were connected to one another through cables. Circuit boards have simplified the connection of electronic machines, which has helped make electronics smaller, less expensive, easier to produce, and more efficient.

The Many Types of Circuit Boards

You may not know that there are many kinds of printed circuit boards available for electronic devices. Here are several examples of circuit boards:

  • Single-Sided
  • Double-Sided
  • Multi-Layer
  • Rigid
  • Flex Circuits
  • Rigid-Flex
  • High-Frequency
  • Aluminum-backed

Circuit boards are highly complex pieces of technology. Circuit boards control the entire device and without them, your device will not work properly. Because circuit boards contain a multitude of complex electrical components, it’s important to hire a professional industrial electronics repair company to fix a damaged circuit board. Common issues that can damage a circuit board include: 

  • Physical damage: A device is dropped or water-damaged
  • Environmental elements: Corrosion or condensation is affecting the circuit board
  • Overheating: This is especially common in older devices
  • Design issues: When a manufacturer does not design a device properly

3 Key Tips to Extend the Life of Your Printed Circuit Boards

printed circuit board repairsAs you probably know by now, printed circuit boards don’t last forever.  Not even the very expensive ones inside your industrial equipment.   But did you know that you can extend the life of your circuit boards? And, potentially put off the need for circuit board repairs a little longer?

The number one reason printed circuit boards need repair is aging components.  There’s not much you can do about that.   But, what about the second biggest reason they end up in repair? That is damage caused by dirt, heat, moisture, and neglect/accidents.  Now THAT is something you  CAN control.

Here’s 3 key tips to save money with good circuit board maintenance:

  1. Clean house. – Clean the dust that accumulates on the PCB boards every 3-6 months. You can also use special cleaning fluid designed for electronics. After all the dust and dirt is cleaned, use a blower to dry the boards before reinstalling them or using the equipment.
  2. Be Proactive – Why wait until your line goes down to troubleshoot…that’s just expensive down time with a side dish of aggravation. Regularly check your PCB components to look for obvious trace damage (usually caused by overheating). Look for burn marks, solder blobs, and broken traces. Check the electrolytic capacitors for bulging or leakage.  Anyone can do this as these are all obvious problems and require no test equipment.

Also, check connectors for signs of corrosion which is common, especially with edge connectors. They can be gently cleaned with an eraser and soft, lint-free/static-free cloth.  Corrosion is a sign of excess moisture so to avoid future damage, find out where the moisture is coming from and eliminate it if possible.

If you are using a device coated with thermal grease, you should check to see if the thermal grease is dried.   If it has become overly dry, gently wipe it out and then coat with new thermal grease to aid with heat dissipation – especially important since we know that too much heat will result in damage.

  1. Protect your PCBs with Good Storage and Handling Techniques
  • Store your electronic equipment in Moisture Vapor Barrier Bags (MVBs). Thicker is better so buy the best you can afford. Vacuum and heat seal the bags to remove as much air as possible.
  • Use desiccant bags to absorb moisture and include a moisture/humidity card which can detect any moisture.   This will let you know if the storage bag has been compromised.
  • Keep your spare circuit boards at a consistent and cool temperature – between 60-70 degrees Fahrenheit
  • If you have many circuit boards or other electronics stored, invest in the best moisture-free environment you can afford. Best choice is a Dry Atmosphere Cabinet to maintain a very low humidity (>5% Relative Humidity). By using this type of cabinet you can forego the MVBs.
  • Locate your electronics storeroom away from dirt, temperature extremes, and moisture, as well as excess vibration. It is best if you have a dedicated and secure Storeroom with strict access records on what parts come and go.

If your industrial circuit board has lasted a solid 10 years before failure – congratulations! You’re doing something right! But if the time has come for repairs and you find yourself searching for a repair center for your damaged electronics, check first to see if your equipment is still under warranty.  If it is still under warranty contact the OEM about repairs.

If it is out of warranty, contact an independent industrial electronic repair center to find out if they are a good fit for your company and your particular repair needs. They should offer free evaluations for your damaged equipment and, if needed, a free quote for repairs (no bench fees!).  They should also provide repair reports if requested and a good warranty of at least one year that covers both parts and labor.

Eight Tips to Keep Your CNC Machine Working Better and Longer

Expert Charmilles CNC Circuit Board RepairsThink about it…if you go to the doctor and he or she treats only your obvious symptoms, are you cured?  Probably not.  Sooner or later the problem will return.  Getting at the root cause of the problem is key to the cure for both humans and machines.

For example, how many times have you or, let’s say somebody you know, replaced a damaged circuit board, only to have the same problem happen again?  The circuit board often takes one on the chin for the team!

To protect your CNC equipment, you must first recognize (and eliminate/reduce) the repeat offenders:  heat, dirt, corrosion, vibration, moisture, current surges, and voltage transients.  Here are eight tips for preventing and dealing with your CNC machines and the control circuit board:

  1. Keep the air flowing, especially in sealed cabinets.  Air conditioning is nice, but expensive.  Just keeping the air flowing past these machines is often enough.  Keep the cooling fan and duct filter clean and functional by inspecting at least every six months.
  2. If problems develop with your CNC, make sure to zero out the machine and move the spindle into the home position before troubleshooting.
  3. Keep things dry and clean.  No sloppy pigs in the machine shop!  (Unless they are soaking up oil!)  Corrosion and dirt are some nasty customers but you may be able to avoid repairs, at least for a little while longer, by simply removing the board and reinstalling /reseating it.  Which doesn’t cost you anything!  The simple action of removing the board is often enough to loosen built up corrosion residue or dirt and reestablish a good connection to buy yourself  some time before you need circuit board repairs.
  4. Lubrication and air are your CNC’s good friends.  Make sure it is getting enough of both.  If the air pressure or oil pressure get too low, the machine will not continue running properly costing you time and money.
  5. Clean out the chip drawer.  I repeat…no sloppy pigs in the shop!  Overfull chip boxes inhibit coolant flow creating excess heat which is never good.
  6. Inspect, or if necessary get someone who knows how to inspect your motor and your memory storage batteries.  Change the batteries for your RAM memory once a year  so you can rest easy knowing that if there is a power failure you will not lose critical information. Don’t forget to back up first!
  7. Have a SPARE circuit board configured and set with the proper dip switch setting if needed and know where it is.  Your CNC machine will invariably break down during a rush job and you will be glad to have that spare.  During slower times, load the spare circuit board into the machine just to test it.
  8. Last but not least, when you finally do need repairs, tell your service provider everything.  Having all the information will speed up the evaluation and repair process.

When you do need CNC circuit board repairs, choose a reputable industrial electronic repair shop that provides free evaluations, good service, and a solid warranty.

Winning Solution For “Jerry-Rigged” Circuit Boards

Unique Solutions for Unrepairable Circuit Boards

Three New Circuit Boards Made From One Original

Sometimes we receive some pretty mysterious repair jobs on the old loading dock.  Recently we received three printed circuit boards that were so, so, well, so “jerry-rigged” that we were wondering how they ever worked in the first place what with the point to point hand wiring, jumpers, and patches all over them.  (Truth is, sometimes I miss the old days working on that loading dock…every day it is full of surprises!)

These “jerry-rigged” circuit board repairs were going to take a lot of man-hours and the cost was going to be pretty high.  The solution we offered this customer was to build them some brand new boards in-house at ACS rather than repair the scary boards – and for lower cost than it would have been to repair them!  Sometimes, the solution to the problem is staring you in the face and you just have to go with it.

There were actually four PCB’s needing repair in this shipment, three as described and one more than had been professionally manufactured.   Ultimately, copying the professional board to make the three new ones provided this customer with a more reliable solution, as well as having the added benefit of being able to reproduce them on-demand in the future from the files that were created.  This was a winning solution in every way.

ACS Industrial Services is here for you.  We want to make sure you always get the best solution that meets your needs in the time you need it.

Are Voltage Regulators Really Necessary?

Get Fast & Accurate Quotes for Expert Industrial Electronic RepairsThe answer to this question could be “it depends”, but I’m going to go right out to end of the tree limb and say the answer is “yes”, voltage regulators are necessary, even here in the United States where the delivery of power is pretty consistent.

Consistent to the extent that it is better than in developing nations, but perfectly consistent? No.  In the U.S. there is a voltage drop of about 3-15% from the point where the electrical service delivers the power to where the power is actually consumed within any given industrial facility, mainly due to wire impedance.

3-15% may sound inconsequential, but multiply this repeatedly and you start to get the picture.  This is especially true for critical or highly sensitive machinery such as MRI and oncology equipment in medical facilities, and recording equipment.

Over time, voltage sags, surges, and variations cause equipment damage, diminish equipment life span, cause digital errors and memory reboots, and production delays which cost you more money by way of:

Ask yourself two questions: What does it cost per hour when your system is down?  How much will it cost to restart the system?  That should tell you whether automatic voltage regulation is important to your operation.

Automatic voltage regulators (AVRs) come in too many sizes, types and applications to list them all.  They can be as tiny as a component on a circuit board and as large as a tractor trailer. Voltage regulation is also the ultimate purpose of units referred to as power conditioners and usually combine that function with voltage drop compensation, surge suppression, short circuit protection, phase to phase voltage balancing, line noise reduction, harmonic  filtering, and more.

To know which of the following sample of AVR’s you will need, you will definitely want to do your homework with your engineer, electrician, and sales reps:

  • Ferroresonant transformer
  • Forroresonant voltage regulator
  • Tap changer
  • Tap-switching voltage regulator
  • Servo voltage regulator
  • Servo voltage stabilizer
  • Motorized variac
  • Variable autotransformer
  • Line drop compensator
  • Step voltage regulator
  • Electronic voltage regulator
  • Constant voltage transformer
  • Magnetic induction voltage regulator
  • On-load tap changer

And that’s just some of the options.

By the way, we do not sell voltage regulator equipment.  We do however repair industrial electronic
equipment and we see the results of this damage every day.  We can repair your damaged equipment and are happy to do so, but we know you would much rather avoid preventable repairs.

The Secret to Success is Not Keeping Success a Secret

Get Great Customer Service With Your Industrial Electronic Repairs at ACSJust yesterday I was listening to a sports interviewer (who shall go unnamed) baiting Terrell Suggs of the Baltimore Ravens by suggesting the team was great but  “stuck” with QB Joe Flacco.  It made me think for a few minutes about why Joe Flacco does not seem to get the media respect that he statistically deserves.  As  I explained to two of my three sons (while waiting for the school bus at 6:20 a.m.!), maybe it’s because he is a pretty low key guy and does not spend much time, for better or worse, tooting his own horn.

After the big yellow school bus pulled away, I thought about this some more and applied it to our business.  An “Aha!” moment.  The secret to success is NOT keeping success a secret – but with at least some degree of dignity.  That same day I received a note from one of our customers that went like this:

“I think everyone at ACS is so prompt and professional and it’s actually a pleasure doing business with ACS. I recommend ACS to everyone I do business with.”

Now, we get quite a few comments like this which reassures me our customer service team members are absolutely the best.  Great repairs are important, but the process shouldn’t be painful.  Superior customer service is the sweet spot…the great differentiator.

If you’ve been getting the runaround from your industrial electronic repair house, give our team a call at 800-605-6419.  We promise we will do everything possible to
get your industrial electronics repaired and returned to you quickly and in good working order … with a pleasant and helpful attitude.

Visit our ACS Industrial Services website too where you can find info on all types of industrial electronic repair services from circuit board repairs to servo drive repairs to monitor & touch screen repairs.  And if you have comments, praise, or yes, even complaints, please let us know.  We do want to hear from you.

And as a final thought, what was that guy thinking baiting Terrell Suggs?!  Hasn’t he seen what this guy does to opposing quarterbacks?  I suspect even Pittsburgh’s Big Ben Roethlisberger dreads facing Mr. Suggs on game day because he knows the next day he is going to be hurting!  Go Ravens!!
