10-layer 2-step blind PCB boards are advanced multilayer printed circuit boards used in complex electronic designs. They feature ten conductive layers with interconnections between non-adjacent layers. The “2-step blind” refers to vias that connect the surface to inner layers but don’t go through the entire board. This design allows for higher component density, improved signal integrity, and better EMI shielding, making them ideal for high-performance applications in telecommunications, aerospace, and military equipment.
