The conductive layers in a multilayer printed-circuit structure can be interconnected by driving metallic pins as small as .002-.003'' in diameter into the structure. The pins are driven in at a very high velocity, approaching projectile velocities, such that the pins penetrate the structure and create intermetallic bonds which form permanent electrical connections between conductive layers.
