Problems solved by technology

[0003] In order to overcome the shortcomings of the above-mentioned various solders, especially when automatic selective point-to-point wave soldering is used to weld PCBA boards with dense solder joints, the work efficiency is low, it is not suitable for large-scale batch processing, and the joints are easy to form virtual soldering. The invention provides a tin furnace spout with simple structure, which can effectively improve welding efficiency and ensure the quality of welding joints

Embodiment Construction

[0012] like figure 1 Shown is a double-sided straddle type part avoidance type spout, the shape of the spout is rectangular, at least one side of the rectangle is provided with a tin overflow port 1, and a part straddle spout is provided on the corner of the spout 2. The tin overflow opening 1 is a rectangular opening with a depth of 3-4mm.

[0013] like figure 2 As shown, the spout of the present invention is mainly applied to the situation where a certain electronic component 3 needs to be selectively soldered on the PCBA board 4, and the part avoidance port 2 is provided on the knuckle of the spout, so that the electronic component Part of the device 3 is set inside the spout, and part of it is set outside the spout, so that the parts of the electronic components 3 located inside the spout are welded. And there is no electronic component 3 outside the tin overflow port 1 or it is far away, so that the tin liquid will not spread and flow to other solder-free electronic c...

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...
