Why Printed Circuit Board Remains a Necessity to Businesses and Industries across the Globe

Integrated circuits found on various devices, gadgets, and equipment contains computer chips with micron scale transistors to provide functionality. They are also designed with buses that are capable of transmitting gigabytes through gigahertz operating speeds. The process is a wondrous phenomenon invented by mankind which remains of great help to electronics industry. The immensely complex structure of printed circuit board is in fact the summit of any human engineering achievement.

Understanding the Essence of PCBs to Electronic Devices

The integrated circuits used nowadays would be worthless if PCBs are not invented. While the IC is the brain of the computer devices, the PCB is the skeleton, lifeblood, and nervous system of the silicon age. However, many people still do not know how a printed circuit board works. On that note, it will be tackled here how these circuit boards are made and how they function to provide basic knowledge to those who might be interested.


And with the complex growth of printed circuit boards in many parts of the world, you really need to consider these products to help your business grow as well. In fact, you are now guaranteed with the highly developed engineering of PCBs that is really something to experience and behold. PCB manufacturing is a complex process but it’s amazing to see how they power up devices commonly used by consumers worldwide. It involves the use of “layer upon layer” of copper, solder, aluminum, resin, polymer, and tin. They are all essential in making circuit boards no matter the purpose of the printed circuit board.

The typical stages of the fabrication process also involves printing masks which are essential in creating copper paths, solder mask, and the dielectric. After the printed circuit board is completed structurally, any legends or text are silk-screened onto the circuit board through the use of basically enormous inkjet printer. And finally, the two major tools to use in automatically testing the PCBs are the automated-optical inspection unit and flying-prove machine. The first one compares the output against the actual CAD design. The latter is used in electrically testing the circuit board’s copper channels.

PCB Types You Should Know About

Below are the common types of PCBs that every individual who’s thinking of entering the manufacturing business needs to be familiar with:

  • FR2 Paper or Phenolic – this is the “grade designation” for artificial resin-bonded paper, meaning it’s a complex material that is formed using paper saturated with plasticized FR2 paper formaldehyde resin. This is important in manufacturing the PCBs until the desired design is achieved.
  • FR4 Epoxy – FR4 printed circuit boards made using woven fiberglass fabric with flame-resistant epoxy resin binder. The water absorption level is near zero and substantial mechanical strength. Hence, the epoxy is frequently integrated as electrical insulators. But the material should hold on to its higher physical values as well as electrical insulating properties in humid and dry conditions.
  • Ultra high-performance FR4 – with the latest highly reliable, battery-powered consumer electronic gadgets used today, PCBs are more important than ever. This is to maximize autonomy while providing people with a premium product they truly deserve. Through ultra high-end applications such as military, aerospace, and servers’ applications, circuit boards meet current demands in these areas.

Other Essential Things to Consider when Buying PCBs Online

And when it comes to electrical properties, computers, smart phones, TV sets, and many other electronic devices contain sophisticated micro-processors. The frequencies are continuously increasing which eventually results to higher electrical performance as well as better signal integrity. For assembly temperatures, new alloys were invented to ensure lead-free solder. The new alloys provide high melting point in order for the polymer substrate contained by PCBs to retain certain properties at high soldering temperatures.


In terms of soldering reliability and moisture uptake, determining lead-free soldering materials is now much easier to do. With lesser moisture in the board, manufacturing business owners get better quality PCBs that they exactly need. So if you have questions about the best printed circuits boards you need right now, you should probably check out the various reputable board manufacturing firms online (such as PCBnet). By spending time to check out their sites, you can find the best solutions to your manufacturing requirements.
