Abstract

The invention relates to a tin furnace component for soldering tin of PCBA plates, in particular to a two-sided straddle type and part-avoiding type spout for the PCBA plates of magnetic induction motors. The spout is in a rectangular shape, wherein at least one rectangular edge is provided with a tin overflow opening; a part straddle opening is arranged on a break angle of the spout; and the tin overflow opening is a rectangular breach of which the depth is between 3 and 4 millimeters. The two-sided straddle type and part-avoiding type spout has a simple structure, can effectively improve the welding efficiency, and is suitable for large-scale automatic production; and in addition, the two-sided straddle type and part-avoiding type spout effectively prevents an oxidation layer of a surface layer of tin liquid from remaining on the surfaces of the PCBA plates, and ensures the quality of welding contacts.

Description

technical field

[0001] The invention relates to a tin furnace component used for PCBA board soldering, in particular to a double-sided straddle-type part-avoidance type spout used for a magnetic induction motor PCBA board. Background technique

[0002] The usual wave soldering is usually manually operated, and the production efficiency is relatively low. For PCBA boards that require dense soldering points, this soldering method is even more insufficient. In addition, because the tin outlet is too small (generally 2 mm long), it will bring Tin slag blocks the mouth of the pot, which leads to a large area of ​​false soldering; for PCBA boards with denser solder joints, there are also pot mouth structures, but the usual tin furnace pot mouth is designed as a flat mouth, in order to realize PCBA board Soldering operation generally needs to keep a distance between the PCBA board and the spout. On the one hand, it is ensured that the tin liquid sprayed from the spout can solder th...
