High density pcb 10 layers

10 layers high density interconnect PCB board made of FR-4, Tg 150 with immersion gold surface treatment.
High-Density Interconnect (HDI) PCB is simply a PCB with more number of interconnections and buried hole, blind hole, occupying minimal space. This results in the miniaturization of the circuit board. The components are placed closer and the board space is significantly reduced but the functionality isn’t compromised.
