Description

Technical Field

[0001] The utility model belongs to the technical field of wave soldering, and in particular relates to a wave soldering tin slag screening device. Background Art

[0002] There are many steps required in the production of circuit boards, one of which is wave soldering. Wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of soldering. The high-temperature liquid tin maintains an inclined surface, and a special device is used to make the liquid tin form a wave-like phenomenon, so it is called wave soldering. Its main material is solder bar.

[0003] During wave soldering operation, solder slag is generated. Currently, the method of screening the solder slag is to scoop the slag with a spoon and sieve the slag with a colander. The slag screening is not clean, and only half a spoonful of slag can be screened at a time, which is inefficient. There is no dust protection during the screening of the slag, and dust flies everywhere. Personnel need to wear high temperature resistant gloves when working, which poses a risk of high temperature burns. Utility Model Content
