HDI PCB, the full name of high density interconnection board, is a high density of high density circuit board. The microblind hole technique was used. HDI PCB There are internal and external lines, and then the internal line of each layer is connected through drilling, hole metallization and other processes. Generally, the stacking method is used, the more stacking times, the higher the technical level of the plate.

Advantages of HDI PCB

  • Low power consumption: There are surprisingly few functions on small circuit boards and long battery life.
  • Better design: One or two sides of the layer use one or two sides of the layer to reduce signal paths to improve signal integrity.
  • Cost-effective: fewer materials used and lower design and manufacturing costs.
