What is HDI PCB

High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter. By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired....

HDI PCBs

HDI (high density interconnection) circuit boards and Microvia Technology are inextricably linked. Microvias are minute holes drilled by a laser to generate the electrical connection between the layers in a multilayer circuit board. Via in Pad microvias play a decisive role in the miniaturisation of circuit boards. “Via in Pad“ means that microvia holes are located directly in the solder pads. As microvias are not blind holes no capillary forces arise. The solder deposit fills the minimum hollo...

HDI – High Density Interconnect PCB

HDI is the abbreviation for High Density Interconnector. HDI PCB is defined as a PCB with a higher wiring density per unit area than conventional PCB. They have finer lines and spaces, smaller vias and capture pads and higher connection pad density than employed in conventional PCB technology. HDI PCB is used to reduce size and weight, as well as to enhance electrical performance of the device. HDI PCB is made through Microvia and buried vias and sequential lamination with insulation materials...
