Pins 1 are connected to plated through holes 2 in a substrate 3 with solder rings 4 by heating them with an infrared ray heater 5. Infrared ray transmitting glass covers 6, 7 with holes formed therein in the pin positions are disposed as illustrated above. These glass covers 6, 7 prevent small solder balls or solder splashes and/or flux gases from contaminating edge portions of the pins 1. A glass plate 8 transmitting infrared rays supports lower edges of the pins 1. By use of screws 9, the position of the glass plate 8 can be adjusted according to the size of the pins 1.
