Title: AN INTERCONNECTION SYSTEM AND PIN FOR DOUBLE FACED PRINTED CIRCUITS BY DOUBLE PROCESS, WAVE AND REFUSION
Abstract:
A pin (17) for double faced circuit boards (10) includes a head (18) which is refusion weldable and a rod portion (19) extending therefrom which is wave weldable. An interconnection system for double faced printed circuits (10) includes a dielectric substrate (11) covered on both faces with a conductive layer (12), both faces electrically communicating with a pin (17) disposed in a metallized hole (16). The system is characterized in that the welding of the electronic components to the conductive layers (12) is made with refusion welding techniques near one end of the pin (17) while the other end is wave welded.
