Abstract

The invention discloses a solder paste welding process for laminating pure nickel and nickel-plated copper materials, comprising: making a special printing screen for laminating pure nickel and nickel-plated copper materials; two-way printing of the sheet; align the two nickel sheets with the nickel-plated copper sheet, so that the error between the two nickel sheets and the nickel-plated copper sheet after lamination is less than the set tolerance standard; Mount and fix the nickel-plated copper sheet with a permanent magnet furnace carrier; adjust the welding temperature, use a mesh belt furnace or track furnace for reflow soldering; use a high-speed heat dissipation fan to cool the nickel sheet printing tool, and check the bonding welding After the nickel sheet product quality. The invention can improve the current resistance performance of the nickel sheet, ensure the welding quality, and have a wider range of product use, especially for the design of lithium battery packs, which greatly reduces the manufacturing cost and equipment investment, and the development of new varieties is fast, with less investment and high quality. High reliability.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a solder paste welding process for laminating pure nickel and nickel-plated copper materials. Background technique [0002] In the assembly of lithium batteries, a large number of nickel sheets or nickel-plated copper sheets are required to meet the connection of lithium battery packs. In the prior art, laser spot welding is generally used for the production of nickel sheets. Although the precision of this process is relatively high High, but the cost of equipment investment is high, and the production process is complicated, and the product production efficiency is relatively low. [0003] Therefore, the prior art needs to be improved. Contents of the invention [0004] The technical problem to be solved by the embodiments of the present invention is to provide a solder paste welding process for laminating pure nickel and nickel-plated copper to solve the problems existing i...
