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.
