Blind hole termination of pin to pcb

摘要

Tails ( 20 ) projecting from an electrical component ( 12 ) that lies on a circuit board surface, are terminated to traces on a multi-layer circuit board ( 14 ) in a manner that minimizes the disadvantages of long through hole soldering and of surface mount techniques. A blind hole is drilled and plated in a first layer ( 31 ) that will become the topmost layer of the stack, to form a shallow well ( 70 ). The well is filled with a soldering composition ( 130 ). A tail ( 20 ) is projected downward into the soldering composition, and the soldering composition is heated to solder the tail to the hole plating.
