Semiconductor Testing / ATE

Semiconductor technologies continue to advance. There is a need for high-precision processing technologies for multilayer/large testing boards to support larger wafers with large pin counts. There is also a need top-rate electrical characteristics, in order to support faster transmission signalling. High-precision/high-detail processing technologies are required to support decreasing package sizes.

We offer semiconductor testing boards, supporting from the background the reliable quality of continually evolving semiconductor devices.
