PCB manufacturing with sophisticated steps
The history of the manufacture of printed circuit boards goes back to the past when the Austrian engineer Paul Eisler used it as part of a radio. Today, Flexible Printed Circuit Boards have become immensely popular in smaller electronic packages.
The printed circuit board manufacturing industry grew only in volume as the demand for smaller electronics became ever larger. One the kind of PCB is flexible printed circuit boards that help in the flexible electronic connectivity of an electronic device like television, phone, music systems, smart devices and so on.
There are two kind of flexible printed circuit boards viz; flex-rigid, simple and double-sided. The basic material for the production of single and double-sided flexible printed circuit boards is capton (polyimide) with a thickness of 50µm + 25µm adhesive + 35µm copper foil. Flexible and rigid FPCs, as the name suggests, are combined using flexible and rigid printed circuit boards.
The subtler nuances of the manufacture of the printed circuit board require a series of sophisticated steps to produce a single or multi-layer printed circuit board. This is by any of the following viz processes; mechanical, chemical, electrical or optical.
However, it should be noted that the PCB manufacturing process leads to the emission of a sufficient amount of chemicals that are hazardous to the environment. Therefore, it is always important to check the quality before and after the manufacturing process of the printed circuit board.
