The history of Printed Circuit Board Manufacturing goes back to the 30s when Austrian engineer Paul Eisler used it as a part in a radio. Today, Flexible PCBs have become immensely popular in smaller electronics packaging.
Over the years, the PCB Manufacturing industry has only grown in volume as the demand for smaller electronic gadgets became higher and higher. The Flexible PC boards help in the flexible electronic connectivity of an electronic device like the TV, the Radio, Music systems, Computers and so on.
Classification of FPC boards:
There are two types of flexible pcbs viz; flex-rigid, single and double-sided. The basic material for the production of single & double-sided flexible PCB boards is capton (polyimide) with the thickness of 50µm + adhesive 25µm + Cu foil 35µm. The flex-rigid FPCs as the name suggest combines using flexible and rigid printed circuits.
The nuances of PCB Manufacturing:
The finer nuances of Printed Circuit Board manufacturing require a series of sophisticated steps to produce single or multilayered PCB. This is through any of the following processes viz; mechanical, chemical, electrical or optical. However, it should be noted that the manufacturing process leads to the emission of sufficient amount of chemicals that are hazardous to the environment. Hence, it is always important to go for quality checking before and after the PCB manufacturing process.
