Problems solved by technology

[0004] 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

[0013] Such as figure 1 Shown is a fixed plug-in spout with an outer stop, the mouth of the spout is provided with a conical socket 1, and at least one overflowing tin opening 2 is provided on the edge of the conical socket 1, and the overflowing tin opening 2 It is a rectangular opening with a depth of 3-6mm. A fixing plate 3 is arranged on the inner wall of the mouth of the pot, a fixing hole 4 is opened on the fixing plate 3, and a baffle 5 is arranged on the outside of the overflow tin mouth

[0014] Such as figure 2 As shown, before welding, the spout and the PCBA board 7 are firmly connected through the fixing holes 4 on the fixing plate 3 through the fixing bolts. Depending on the distribution situation, usually the electronic components 6 on the PCBA board outside the tin overflow port 2 are relatively far away from the tin overflow port 2, and the flow is blocked by the baffle 5 so that the tin liquid flowing from the tin overflow port will not spread and overflow....

Abstract

The invention relates to a tin furnace part used for PCBA board soldering tin, in particular to a fixed plug-in pot opening with an outer block. The mouth of the pot opening is provided with a cone-shaped socket, the edge of the cone-shaped socket is provided with at least one tin-overflowing port, the inner wall of the pot opening is provided with a fixed plate with a fixed hole, and the outer side of the tin-overflowing port is provided with a block sheet. The invention with simple structure is suitable for large-scale automated production; furthermore, the invention not only can effectively increase the welding efficiency and effectively avoid the remaining of oxidizing layer of tin liquid surface on the surface of the PCBA board, but also can ensure the quality of the welding joints.

Description

technical field [0001] The invention relates to a tin furnace component used for PCBA board soldering, in particular to a fixed plug-in spout with an outer stop. 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 s...
