PCB板廠家打樣工藝

目的 PCB打樣 是在大規模生產之前製作少量樣品以測試產品品質, 在一定程度上, 避免未來大規模生產的風險. 所以, 什麼是校對過程 PCB板製造商?

The first step: check the information
Before production, 我們將檢查客戶提供的電路板製作資訊, 包括董事會規模等相關資料, 工藝要求, 和產品數量, 與客戶達成協議後再進行下一步生產.

Step 2: Cutting
According to the board 材料 given by the customer, 切割小塊 生產板 在符合要求的電路板上. 具體操作：大板-按MI要求切割板-curium板-啤酒片 / 邊緣-彈出板.

Step 3: Drilling
Drill the required hole in the corresponding position of the PCB板. 大板料.符合MI要求的切割板.curium板.啤酒片 / 封邊-板出.

Step 4: Immerse the copper
A thin layer of copper is chemically deposited on the insulating holes. 具體操作：粗磨-掛板-自動沉銅線-下板-浸1%稀H2SO4-加厚銅.

Step 5: Graphics transfer
Transfer the image on the production film to the board. 具體操作：麻板壓片靜止對準曝光靜止印刷檢查.

Step 6: Graphic plating
Electroplating a copper layer with the required thickness and a gold-nickel or tin layer with the required thickness on the exposed copper skin or hole wall of the circuit pattern. 具體操作：上板-脫脂-水洗兩次-微蝕刻-水洗-酸洗-鍍銅-水洗-酸洗-鍍錫-水洗-下板.

Step 7: Unwind the film
The anti-electroplating covering film layer is removed with NaOH solution, 露出非電路銅層.

Step 8: Etching
Remove the non-line parts with chemical reagent copper.

Step 9: Green Oil
The graphics of the green film are transferred to the board, 主要用於保護電路，防止焊接零件時電路上的錫.

Step 10: Characters
Recognizable characters are printed on the PCB板. 具體操作：綠油完成後-冷卻並放置-調整荧幕-列印字元-後curium.

Step 11: gold-plated fingers
A nickel/在插頭的手指上鍍上所需厚度的金層，使其更加堅硬和耐磨.

Step 12: Forming
The shape required by the customer is punched out with a die or a CNC gong machine.

Step 13: Test
It is not easy to find functional defects caused by open circuit, 短路, 等. 通過目視檢查, 可通過飛針測試儀進行測試.

以上是該產品的打樣過程 PCB板廠, 我希望這對你有幫助!
