Inner layer drilling and electroplating:
According to the design requirements, accurately drill holes on the inner plate.
Then, electroplating is carried out in the borehole to form a metal layer in the hole, thereby conducting current.
Lamination:
The inner layer board with buried holes is precisely laminated with other layers to form a complete multi-layer PCB board structure.
External processing:
In order to complete the manufacture of PCB, the outer layer treatment is carried out on the laminated multilayer board, including the production of copper foil pattern and the coverage of solder mask.
Quality control and inspection:
In the whole processing process, we implement strict quality control measures to ensure that every step meets the design requirements and quality standards.
After the processing is completed, careful quality inspection is carried out, including the accuracy of the hole location, the flatness and conductivity of the hole wall, etc., to ensure the reliability and stability of the product.
