HDI Board production process:

At present, HDI board interconnection between layer and layer is mainly the following design: Staggered holes interconnection, Cross-layer interconnection, ladder interconnection and superposition holes interconnection. Among them, the superposition holes interconnection occupy the least space. There is a research suggests that reducing the number of through holes and increasing the number of blind holes can effectively improve the wiring density. And in the superposition interconnection, the methods of electroplating and resin plug are mainly used, especially the electroplating hole filling method which has more obvious advantages like high reliability and good conduction performance. Therefore, superposition interconnection is the most widely used design method for blind holes design. The process of stacking between layers is as follows: first blind hole is made, then second blind hole is made after lamination, then multi-blind hole is made according to this method, and the interconnection between layers is realized by electroplating hole filling method.

On the whole, the production process of HDI plate is complex, which needs to be completed after many times of production for a long time. It’s not only high requirements for the accuracy and shrinkage control of each layer, but also high standards in materials, equipment, environment and technical personnel.
