Quick Overview of Printed Circuit Board Assemblies

For starters, a printed board circuit, often referred by the acronym PCB, is designed to mechanically support and electrically connect various electronic components by using various features such as pads and tracks that have been carefully etched out of laminated sheets of copper onto some type of substrate that is non-conductive.

Simply put, printed circuit boards are designed with intricate metallic insertion pathways. Each of these pathways is designed to help transfer electricity seamlessly so it ultimately reaches components of electronic devices. By creating easy movement, electrical power allows for a more fluent operation of the device, one without any disruption.

Printed circuit board assembly is actually the process involved whereby all electronic components are connected with the different wirings of the printed circuit board. The pathways, also referred to as traces, are conductive and engraved onto the copper and used within non-conductive substrate. With this, the assembly is complete.

The final action prior to an electronic device becoming fully functional is that the electronic components have to be attached to the printed circuit boards. Because of the work involved, an expert must take special care to pay extremely close attention to every detail. This type of work has to be meticulous and precise in order for an electronic device to operate correctly.

There are three ways to create printed circuit board assemblies. The first is known as surface mount assembly, which consists of components that have metal tabs being soldered to the printed circuit board using a proven method of soldering. The result is a higher circuit density as long as components are affixed on both sides.

The second method for assembly is plated through-hole technology. In this case, leads are attached to the components. The printed circuit boards used with this particular type of assembly have holes already drilled. Finally, there is the electro-mechanical assembly, which is sometimes called the box-build assembly. To assemble printed circuit boards with the electronic components, various elements are used such as cable assemble, molded plastics, wire harnesses, custom metalwork, and looms.
