[Case Study] Surface Treatment Using "Sn-Cu Based Lead-Free Solder Reflow"

Achieving cost reduction and quality improvement in surface treatment during parallel production of printed circuit boards both domestically and internationally.

In addition to domestic factories in Japan, we have also expanded our printed circuit board factories overseas, producing the same product range in both domestic and overseas factories while considering product difficulty and pricing. Domestic printed circuit board manufacturers faced cost challenges due to production in overseas factories. For products with a wide variety, there were significant differences in product difficulty. Therefore, relatively low-difficulty products were prioritized for cost-effective production overseas, while high-difficulty products were produced domestically with a focus on quality. As a result, we introduced cost-effective Sn-Cu-based solder for surface treatment overseas. This not only reduced costs from production in overseas factories but also improved overall quality by aligning operations between domestic and overseas facilities.
