process and apparatus for the welding of components on printed circuit plates through the bathroom saldanti alloys

摘要

a process and apparatus for the welding of components on printed circuit boards by means of bath on base alloys saldanti the fusions with the techniques in the air, stramazzo.vibration, static etc, including in sequence the following stages: flussatura (2), (3), at least one preheating washing (4, 5), (6) replacement solventsfurther flussatura (7), (8) any preheating, welding (9) and whether washing light (10), in which the stages (4) to (8) are performed in a controlled atmosphere or in vacuum.
