Auxiliary soldering device and method for PCB components

Abstract

The invention relates to the field of wave-soldering and particularly provides an auxiliary soldering device and method for PCB components. The auxiliary soldering device comprises carrier shielding templates and a template switching mechanism. The carrier shielding templates comprise the left template and the right template, first through holes used for exposing first soldering positions of a PCB are formed in the left template, second through holes used for exposing second soldering positions of the PCB are formed in the right template, and the template switching mechanism is used for controlling the left template and the right template to be switched at the position of a wave crest spraying opening. When soldering at the first soldering positions is finished, soldering at the second positions is directly conducted after the right template is switched to the position of the wave crest spraying opening, and separated soldering of the first soldering positions and the second soldering positions is achieved; furthermore, due to the fact that only one carrier and one wave crest spraying opening are needed, the production and maintenance cost is lowered, and the production technology is simplified.

Description

technical field [0001] The invention relates to the field of wave soldering, in particular to a soldering auxiliary device and method for PCB components. Background technique [0002] Group soldering is a kind of selective wave soldering. It customizes different nozzles according to different PCB board pin positions, which can realize simultaneous soldering of the entire PCB board, with high efficiency and stable quality. In some PCB welding processes, due to the requirements of special components, the welding process has special characteristics. For example, battery welding requires that the positive and negative electrodes must be welded separately. Even a short-term tin short circuit during welding may cause damage to the components; For a class of components, almost all of them are soldered by hand, or two sets of carriers and two sets of wave spouts are designed, one for positive electrodes and one for negative electrodes; Resource costs are increasing year by year, an...
