Double sided PCB of industrial personal computer
Double sided PCB manufacturing parameters：
Double-sided PCB proofing PCB fiberglass board 2 layers
1. The 70-minute electrographic time ensures the copper thickness of the hole is 18-22um and the thickness of the surface copper is greater than 35um
2. Do backlight test after copper precipitation to ensure the adhesion of copper hole
3. Make slice analysis after etching to ensure the copper thickness of the hole and the copper thickness of the surface
4. AOI optical scanning to ensure the pass-through rate of the circuit (prevent open circuit, short circuit and short circuit)
5, high-speed screw needle machine test, ensure the yield of the board
6, soldering using LED parallel exposure machine exposure
7. High-precision laser text printing.Ensure the clarity and accuracy of the text
High quality sheet
For the core material of the circuit board, the A-grade military material is used, and the quality is very guaranteed.
Exquisite printing process
It adopts Guangxin photosensitive ink, which conforms to environmental protection standards. After high temperature baking, the ink color is bright and bright, and the characters are clear.
Refined production process
A variety of surface treatment processes: gold finger, immersion gold, spray tin; a variety of solder mask color: green, blue, red, yellow, white, matte black, matte green, purple.
Faster and more punctual delivery
We will deliver the samples to you in a timely manner within the promised time.
