HDI PCB Show 1

 HDI board is a kind of circuit board with high circuit density, which uses the technology of micro blind hole embedding. HDI board has inner circuit and outer circuit, and then uses drilling, hole metallization and other processes to connect the inner circuit of each layer.

HDI board is generally manufactured by the stacking method. The more the stacking times, the higher the technical grade of the board. The common HDI board is basically one time stacking, and the high-level HDI adopts two or more times stacking technology. At the same time, advanced PCB technologies such as stacking holes, electroplating filling holes, laser direct drilling are used
