Production and inspection process
01. Board cut
Cut large sheets into small sheets of various specifications
02. Inner layer imaging
Form the inner layer circuit pattern on the copper foil of the board
03.Inner AOI inspection
Detect whether the circuit board has open circuit or short circuit defects
04.Browning
Perform copper surface treatment on the production board to generate an oxide layer on the surface of the inner copper foil to improve the bonding force between the copper foil and the epoxy resin when the multilayer circuit board is pressed
05. lamination
The copper foil, PP sheet and the inner layer circuit board after oxidation treatment are pressed into a multilayer board
06.Drilling
Drill through holes, plug-in holes and tool holes for line connections between layers on the circuit board
07. Electroless copper deposition
Metallize the non-conductor part on the hole wall to facilitate subsequent copper electroplating
08. Outer layer imaging
Make the outer layer to connect the inner and outer layers completely
09. Copper plating
Add the copper thickness of the non-film part to the thickness required by the customer
10.Outer layer fading, etching and tin
Manufacture the circuit designed by the customer
11.Outer inspection
Detect whether the circuit board has open circuit or short circuit defects, and pick out defective products
12.Solder mask
Prevent the solder overflow from causing short circuits, prevent non-soldering points from being contaminated with solder, and effectively protect the circuit board from moisture
13. legend
Facilitate maintenance and identification
14.Surface treatment
Protect the copper surface and provide favorable conditions for the subsequent process
15. Routing
Through die stamping or CNC routing machine rout the shape required by the customer
16.Testing
Ensure that the shipped products will not have functional problems
17.Final inspection
Ensure the quality of shipping circuit boards
18. Package
Prevent the circuit board from getting damp and affect the welding effect
