Printed Circuit Board Manufacturing Process

A self contained module of interconnected electronic components forms a Printed. PCBs or printed are formed with the help of a thin layer of conducting material, either printed on the surface board, or conducting material. And a PCB created with populated electronic components is called a printed circuit assembly (PCBA).

PCB Manufacturing needs to follow a specific procedure, keeping in mind all the minute details of its design. To execute the creation of board, you need to follow some steps. Following are some steps required in Circuit Board Manufacturing:

1.Setup – The process of Circuit Board Manufacturing can easily take a toll from you, if not done properly. So, you need to take care of some basic things like process, material required, customer specifications, and most of all customer’s satisfaction. pcb manufacturer 

2.Patterning | Etching – Etching does not literally mean engraving, but has to do something with it. In this, copper and other unprotected areas are exposed by the etch resist film to remove the unprotected copper. This leaves the protected copper pads and traces in place. However, advanced and newer processed use plasma or laser etching instead of using chemicals for Circuit Board Manufacturing.

3.Engraving photos – In this, a photo mask is combined with chemical etching in order to subtract the copper areas from the printed boards.

4.Multilayer Pressing – One of the most important steps in PCB Manufacturing. This involves aligning of conductive copper and insulating di-electric layers. This is done to form a solid board material.

5.Drilling – Quite clearly, this involves drilling of holes and the information is on stored on the location, where the hole is supposed to be drilled.

6.Masking – A protective layer is applied over the copper, which has a thin layer of solder mask and copper traces around it. This is called masking.
