At Nippon Belparts Co., Ltd., we conduct fine joining processing. Soldering and plating operations for components in high-density mounting of small electronic device parts face challenges such as difficulty in quality assurance, complexity of processes, and ultimately high costs. The materials we propose involve a laminated solder on TA material (sheet and wire), which does not peel off even after punching, bending, or twisting. Soldering can be easily performed after processing the components. Additionally, based on our developed technology, we propose various micro joining solutions. 【Micro Welding and Joining】 ■ Types: Laser welding, TIG welding, resistance welding, spot welding, silver brazing ■ Product examples: Welding of medical catheter components, processing of steel belts *For more details, please refer to the PDF document or feel free to contact us.
