Phiên bản hoàn chỉnh tiến trình sản xuất PCB
Hôm nay mang đến cho bạn một phiên bản hoàn chỉnh PCB quá trình sản xuất, Tôi hy vọng anh có thể hiểu rõ hơn về... PCB sản xuất!
PCB--Cut Lamination
Objective: according to the requirements of the engineering data MTôi, the large sheet meeting the requirements is cut into small pieces of production sheet and small pieces to meet the requirements of customers
Tiến: large board cutting according to MI requirements
PCB--Drill hole
Objective: according to the engineering data, drill the required hole diameter at the corresponding position on the plate with the required size
Process: lamination - put on board - drilling - put off board - inspection / sửa
PCB--PTH
Objective: to deposit a thin layer of copper on the wall of insulating hole by chemical method
Process: rough grinding - hanging plate - automatic copper sinking line - lower plate - dilute H2SO4 - increase copper
PCB--Dry film
Objective: graphic transfer is to transfer the image on the production phim cho hội đồng
Process: (solder mask process): board grinding - printing the first side - drying - printing the second side - drying - exposure - developing - inspectionï¼ Dry film process: pressing film - standing - alignment - exposure - standing - developing - inspectionï¼
PCB--Etching
Objective: etching is to use chemical reaction method to remove the copper layer of non circuit parts
PCB--Solder mask
Objective: solder mask is to transfer the graphics of green ink, film to the board, so as to protect the circuit and prevent the tin on the circuit when welding parts
Process: grinding plate - printing photosensitive green oil - curium plate - exposure - development; board grinding - printing the first side - drying plate - printing the second side - drying plate
PCB--Silk screen
Objective: silk screen is a kind of mark which is easy to identify
Process: solder mask after final curium - cooling and standing - screen adjustment - character printing - back curium
PCB--Surface treament
Objective: to coat a nickel / Lớp bằng vàng với độ dày cần thiết trên ngón trỏ, so as to make it have more hardness and wear resistance
Process: grinding board - degreasing - twice water washing - micro erosion - twice water washing - pickling - copper plating - water washing - nickel board - washing - gold plating
PCB--Outline
Objective: through the mold stamping or CNC chiêng machine gongs out of the customer needs the shape forming method, hữu cơ, Bảng bia, gongs, hand cut
Note: the accuracy of data gong machine board and beer board is higher than that of hand Gong, chỉ có thể tạo ra những hình dạng đơn giản
PCB--Test
Objective: to detect the open circuit, short circuit and other defects that are difficult to find by visual inspection
Process: mold loading - board setting - test - qualified - FQC visual inspection - unqualified - repair - return to test - OK - reject - scrap
PCB--Final inspection
Objective: through 100% visual inspection of plate appearance defects, và sửa chữa lỗi nhỏ, to avoid problems and defective plate outflow
Specific work process: incoming materials - check data - visual inspection - qualified - FQA spot check - qualified - packaging - unqualified - treatment - check -OK
