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] Such as figure 1 Shown is a plug-in spout with an outer stop, the mouth of the spout is provided with a tapered socket 1, at least one tin overflow port 2 is provided on the edge of the socket 1, and a tin overflow port 2 is provided on the outside of the spout 2 The blocking piece 3 is fixedly connected with the outer wall of the socket 1 . The tin overflow port 2 is a rectangular hole with a depth of 3-4mm.

[0013] Such as figure 2 As shown, the spout of the present invention is mainly applied to the welding of electronic components 4 with short single-row leads. The baffle 3 well restricts the flow of liquid tin flowing from the overflow port 2 to the outside of the baffle, and protects the electronic components 4 outside the baffle 3 without soldering. On the PCBA board 5 , there are no other electronic components 4 outside the single row of leads or they are relatively far away, so that the tin liquid flowing out from the overflow tin opening 1 will not flow o...

Abstract

The invention relates to a tin furnace component used for PCBA board soldering tin, in particular to an insertion type tin furnace pot opening. A conical insertion opening is arranged at the opening part of the pot opening, the edge of the insertion opening is provided with at least one tin overflowing opening, the outer side of the tin overflowing opening is provided with baffle sheets, the baffle sheets are fixedly connected with the outer wall of the insertion opening, and the tin overflowing opening is a rectangular hole with the depth between 3 and 4 mm. The invention has a simple structure, can effectively improve the welding efficiency, and is suitable for large-scale automatic production, in addition, an oxide layer of the surface layer of the tin liquid is effectively prevented from being remained on the surface of a PCBA board, and the quality of welding points is ensured.

Description

technical field [0001] The invention relates to a tin furnace component used for PCBA board soldering, in particular to a plug-in tin furnace pot. 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 the electrical components on the PCBA board above, and at the same time, it is...
