High Density Interconnect PCB

General Information for High density pcb (HDI PCB)

HDI pcb is the abbreviation for High Density Interconnect pcb or High Density pcb.An HDI PCB is defined as a printed circuit board with a higher wiring density per unit area than a conventional PCB.
HDI includes the use of fine features or signal traces and spaces of 0.003” (75 µm) or less and laser-drilled blind or buried microvia technology. Microvias allow the use of micro-interconnects from one layer to another within a PCB utilizing a smaller pad diameter creating additional routing density or reducing form factor.
High Density PCB is used extensively in applications and industries including:
● Cell phone
● GPS
● Telecom
● ASemiconductor
● Automotive
● Military
● Medical
● Instrumentation
