The specific process of PCBA

1) Conventional double-sided process flow and technology.

① Material cutting—drilling—hole and full plate electroplating—pattern transfer (film formation, exposure, development)—etching and film removal—solder mask and characters—HAL or OSP, etc.—shape processing—inspection—finished product
② Cutting material—drilling—holeization—pattern transfer—electroplating—film stripping and etching—anti-corrosion film removal (Sn, or Sn/pb)—plating plug- –Solder mask and characters—HAL or OSP, etc.—shape processing—inspection—finished product

(2) Conventional multi-layer board process and technology.

Material cutting—inner layer production—oxidation treatment—lamination—drilling—hole plating (can be divided into full board and pattern plating)—outer layer production—surface coating —Shape processing—Inspection—Finished product
(Note 1): The inner layer production refers to the process of the in-process board after the material is cut—pattern transfer (film formation, exposure, development)—etching and film removal—inspection, etc.
(Note 2): Outer layer fabrication refers to the process of plate-making via hole electroplating—pattern transfer (film formation, exposure, development)—etching and film stripping.
(Note 3): Surface coating (plating) means that after the outer layer is made—solder mask and characters—coating (plating) layer (such as HAL, OSP, chemical Ni/Au, chemical Ag, chemical Sn, etc. Wait).

(3) Buried/blind via multilayer board process flow and technology.

Sequential lamination methods are generally used. which is:
Material cutting—forming core board (equivalent to conventional double-sided or multi-layer board)—lamination—the following process is the same as conventional multi-layer board.
(Note 1): Forming the core board refers to the formation of a multi-layer board with buried/blind holes according to the structural requirements after the double-sided or multi-layer board is formed by conventional methods. If the aspect ratio of the hole of the core board is large, the hole blocking treatment should be carried out to ensure its reliability.
