Understanding The Multilayer PCB Fabrication Process A huge question for people interested in PCB's (Printed Circuit Boards) are first, what are PCBs made of? The basis of most quality printed circuit boards use FR4, which is a rigid type of fiberglass laminate.
The first step in the PCBA manufacturing process is to manufacture the printed circuit board. From bare copper clad PCB boards, the pattern of traces is created using a photomask and a thin layer of photoresist material to cover the boards. Etching machines are then used to remove the copper from the areas of the board where it is not needed.

Manufacturing Processes for a Multilayer PCB Section through PCB Via hole SMD Pad The following presentation covers the main processes during the production of a multilayer PCB. The diagrams which follow represent a section through a 6 layer PCB, as indicated in red.
The manufacturing process of the PCB begins with a "substrate" made of glass epoxy (Glass Epoxy) or made of base with something similar material. The first step in the production is to create wiring that connects the parts. We use a subtractive transfer method to present the working film on a .
Naturally, financial constraints preclude inspecting every PCB after every manufacturing step. So, processcontrol engineers and qualitycontrol managers must decide how to balance the cost of inspecting PCBs against the profits gained from increasing PCB yields. The uses of AOI fall into two general categories: prevention and detection.
Jul 31, 2018· Manufacturing process of fourlayer PCB board: Clean In order to get a good quality etching pattern, it is necessary to ensure that the corrosion resistant layer firmly combines with the surface of the substrate, requiring that the substrate surface is free of oxidation layer, oil, dust, fingermark and other ...
