What Every Hobbyist Should Know About Assembling A Printed Circuit Board

There was a time when people had to suffer through electrical failures in their appliances. This was due to the internal issue of congestion at the junction where the electrical wires met. That time was before the printed circuit board or the PCB was introduced. The PCB has eliminated the need for a whole bunch of electrical wires that perform specific functions inside a bulky television or radio set. By using a PCB, manufacturers are able to simplify and minimize the wirings.

There are a lot of other advantages that the printed circuit board has provided to the world, and all of these advantages are related to the continuous development of modern technologies that give humans a more comfortable and leisurely existence. And because the PCB is such a necessity in the world of technology today, PCB assembly has now turned into a favorite hobby for most people.

PCB assemblyFor those of you who do not know what a PCB is, just know that it is that thin plate-like thing that can be found inside electronic devices such as phones, TV sets, DVD players, and the like. The plate often has diagrams and buttons and tiny battery-looking stuff that make it look like the map that extra-terrestrials use in trying to locate planet Earth. It is not an alien map but the one thing that makes human technology run.

The Different Components Of The Fully-Assembled Printed Circuit Board Are As Follows:

Before the printed circuit board is installed inside a piece of technology, it undergoes a lot of different processes first. The process starts from molding, cutting, and semi-curing the primary substrate that is made of woven fiber glass. It is then drilled and plated with holes that would be used later for attaching the different components of the fully-assembled printed circuit board. After this, the printed circuits are then drawn onto the substrate through different processes:

Adding copper plates onto the surface of the substrate as a mold for the unplated circuit pattern, or
Covering the entire surface of the substrate with copper or tin plating and then etching away all the parts of the plating that covers the portion of the substrate where the circuit pattern should be.

Once the circuit pattern is filled in with either of the above processes, the semi-completed PCB would then undergo the final stages. This includes adding three layers of plating to cover the contact fingers, fusing the board’s coating to protect the PCB’s surface from oxidizing, and then placing additional protective materials over the surface of the PCB.

As soon as every piece of protective gear is in place, it is then time to assemble the different components that make up the entire electrical system of a TV, a smartphone, a computer, or any other piece of electronics. Or, the manufacturer sends out the un-assembled PCB plate so that someone else can attach the components to it.

This is where hobbyists come into the picture.While a hobbyist lauds his own genius for being able to do such a complicated process as assembling PCB components, he is actually just finishing up the process and would be doing the simplest task. This is because attaching the components to a printed circuit board would merely require him to follow the schematic diagram or the circuit pattern shown on the plate.

Of course, there would still be a lot of soldering and inserting caps on holes. And the hobbyist would have to own a complete set of tools, especially a soldering iron, a wire cuter, and pliers so that he can accomplish the job well. He would also be handling the difficult task of testing the PCB for defects in any of its components, which would require the use of a volt-meter.
