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 A fixed plug-in spout is shown, the mouth of the spout is provided with a tapered socket 1, and at least one overflow tin port 2 is provided on the edge of the tapered socket 1, and the overflow tin port 2 is a rectangular Gap, the depth of which is 3-6mm. A fixing plate 3 is arranged on the inner wall of the spout, and a fixing hole 4 is provided on the fixing plate 3 .

[0014] Such as figure 2 As shown, before welding, the spout and the PCBA board 6 are firmly connected through the fixing holes 4 on the fixing plate 3 through the fixing bolts. Depending on the distribution, usually there is no electronic component 5 on the PCBA board outside the tin overflow port 2 or it is relatively far away, so that the tin liquid flowing from the tin overflow port will not spread and other electronic components around the tin overflow port 5 on.

[0015] When in use, place the PCBA board at a predetermined position above the spout, and keep a certain distanc...

Abstract

The invention relates to a tin stove component used for PCBA plate soldering tin, in particular to a fixed insertion type pot mouth. The mouth part of the pot mouth is provided with a conical faucet, the edge of the conical faucet is provided with at least a tin overflowing mouth which is a rectangular gap with the depth of 3 to 6 mm, a fixed plate is arranged at the inner wall of the pot mouth, and the fixed plate is provided with a fixing hole. The invention has simple structure, can effectively increase the welding efficiency and is suitable for large-scale automatic production, and additionally, an oxide layer on the tin liquid surface is effectively prevented from being left on the surface of a PCBA plate, and the quality of welding joints is ensured.

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. 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 gua...
