Reduction of contact resistance of electrical contacts supporting high-speed signal transmission and realization of stable solder wettability with weakly acidic tin-silver alloy plating DAINTINSILSBB6.
In high-speed signal transmission environments of data centers, reducing contact resistance at electrical contacts is extremely important for maintaining stable communication quality. Particularly in miniaturized connectors and chip components, good solder wettability and stable coating quality are essential for maintaining product reliability. The neutral tin plating additive DAINTINGOOD303 supports reliable component manufacturing under a wide range of working conditions. 【Usage Scenarios】 - Electrical contacts of high-speed communication connectors for data centers - Mass production processes using barrel plating 【Benefits of Implementation】 - Improved reliability of electrical contacts due to stable coating quality - Issues with silver replacement at the anode - No occurrence of whiskers observed in tin-plated coatings.

basic information
**Features** - A semi-gloss coating with a eutectic composition (Ag: 3.5 wt%) can be obtained using a tin-silver alloy plating bath for barrel plating. - Plating is possible on materials that are weak against acids and alkalis in a weakly acidic bath (pH 5.0). - There is no occurrence of whiskers observed in the tin plating coating. - Coating properties such as solderability, heat resistance, and adhesion are equivalent to those of tin-lead alloy plating coatings. - The pH variation of the plating bath is small, demonstrating excellent long-term stability. - It can suppress the silver replacement issue at the anode. - There is no need for post-treatment with sodium phosphate after tin-silver alloy plating. **Our Strengths** The Daiwa Chemical Group develops unique chemical businesses in niche markets that major manufacturers do not engage in, under the spirit of "San Sou." Our value lies in introducing new products to the world through original technology development that does not imitate others.
