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 outlet with simple structure, which can effectively improve welding efficiency and ensure the quality of welding joints

Embodiment Construction

[0012] As shown in Figure 1, a single-open tin outlet with a long tin overflow port, the shape of the tin outlet is rectangular, and at least one overflow tin port 1 is arranged on the long side of one of the sides of the rectangle, so The overflow tin opening 1 is a rectangular opening with a depth of 2-8 mm.

[0013] As shown in FIG. 2 , the tin outlet according to the present invention is mainly applied to the welding of electronic components 3 with long single-row leads, and the section line in the figure represents the overflow tin outlet. According to the distribution of the lead wires to be welded on the PCBA board 2 and the distribution of the electronic components 3 near the tin outlet, the overflow tin outlet 1 on the long side of the tin outlet is reasonably set: for the welding of continuous long single-row leads, in the corresponding position Set a long overflow tin outlet 1 on the tin outlet of the tin outlet. For the welding of discontinuously arranged single-ro...

Abstract

The invention relates to a tin furnace part of PCBA board soldering tin, in particular a tin outlet of a tin furnace. The tin outlet is in a rectangle shape, and a long side on one side of the rectangle sides is provided with a tin spill-way which is a rectangle opening with a depth of 2mm to 8mm.The invention has a simple structure and is capable of effectively increasing soldering efficiency and is applicable for large-scale automatic production; furthermore, oxidation layer on molten tin surface layer is effectively prevented from being retained on the surface of the PCBA board, and the quality of soldering spots is ensured.

Description

technical field [0001] The invention relates to a tin furnace component used for PCBA board soldering, in particular to a tin outlet of the tin furnace. 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 tin outlet, resulting in a large area of ​​virtual soldering; for PCBA boards with denser solder joints, there is also a tin outlet structure, but the usual tin furnace outlet is designed as a flat opening. The soldering operation of the PCBA board generally needs to maintain a distance between the PCBA board and the tin outlet. On the one hand, it is ensured that the tin liquid sprayed from the tin outlet can solder the electrical components on the upper PCBA board. The tin liquid spraye...
