Since its establishment, Cotest has been dedicated to the R&D and production of test & measurement (T&M) methodologies, functional test modules, integrated test systems, and automated test equipment (ATE) for general-purpose integrated circuits and optoelectronic devices. Our product portfolio has grown into a comprehensive lineup, covering the entire testing process from wafers (including full wafers, wafer fragments, and bare dies) to modules (such as packaged chips, COB, and COC), and spanning every stage from R&D to mass production testing.
Our customers are active across various sectors, including product prototyping, chip manufacturing, performance evaluation, packaging testing, quality control, incoming inspection, and system performance verification. This extensive industry-wide validation has driven continuous iteration of our products, keeping close pace with rapidly evolving technologies and market demands.
