How to process pcb multilayer buried blind holes?

"When it comes to the blind hole processing of PCB multilayer, Shenzhen Jieduobang adopts a series of high-precision and reliable processes to ensure the quality and performance of the final product. The following are the detailed steps about how to process the buried blind hole of PCB multilayer board:

For details, please visit official website Consulting

Inner layer drilling and electroplating:

Drill holes accurately on the inner layer board according to the design requirements.

then, electroplating is carried out in the drilled hole to form a metal layer in the hole so as to conduct current.

lamination:

accurately laminate the inner board with buried holes with other layers to form a complete multi-layer PCB board structure.

external processing:

external processing is carried out on the laminated multilayer board, including the production of copper foil patterns and the covering of solder mask, etc., so as to complete the manufacture of PCB board.

quality control and inspection:

in the whole processing process, we implement strict quality control measures to ensure that each step meets the design requirements and quality standards.

after finishing the machining, carry out detailed quality inspection, including the accuracy of the hole position, the flatness of the hole wall, the electrical conductivity, etc., to ensure the reliability and stability of the product.
