摘要： A circuit board has holes extending therethrough, and a solder layer disposed on a first side of the board. Terminals have been pushed through respective holes and into contact with the solder layer. The terminals have been welded to the first side of the circuit board in a fluxless manner by an irradiated energy beam.

摘要： Load terminals are mounted to a circuit board by providing a solder layer on each lead terminal and on each conductive inner wall surface of respective holes formed in the circuit board. The lead terminals are thrust into respective holes, and contacting portions of the solder layers are irradiated with an energy beam, to produce sufficient heat for welding in a fluxless manner each lead terminal to the inner wall surface of its respective hole.
