Injectable Solderable Terminal Pins

Pins 1 and 2 can be injected into printed circuit board PCB and thereafter heated to allow solder previously coated on them to now freely and establish electrical connections with conductors in PCB.

Pin 1 has a square, lower portion 3 twisted relative to an upper portion 4. Pin 1 is injected into PCB so that the lower portion first punches a hole in PCB. Then the upper portion lodges in PCB with sufficient clearance to allow the solder to flow freely in the clearance between the flat sides of the pin and the adjacent walls of the hole in which the pin is lodged.

Pin 2 has a cylindrical lower portion 5 that punches a circular hole in PCB and a square upper portion 6 that is lodged in PCB. The flat sides of portion 6 provide clearances permitting the free flow of solder in the hole and along the pin.
