Providing leading surface finish technologies

In today’s high-density interconnect world, board fabricators and end-users alike, demand alternative surface finishes that combine high yields, low cost, increased functionality, and ease of fabrication and assembly. In keeping with our market served approach to the industry, we provide a full line final finishes to meet a variety of customer needs.

Final finishes can be permanent, becoming an integral part of the assembled board, or sacrificial, preventing copper oxidation and preserving solderability through the assembly process. Years of proven results are one of the principle reasons why our final finishing products are a critical part of many of the world's leading OEM electronics.
