Fully Integrated, Pre-Validated Solutions

With leading technology and expertise in all critical elements of the test cell, Cohu is a supplier of all elements of test cell and is able to provide our customers fully-integrated, pre-validated solutions including the tester, handler, device under test (DUT) interface board and contactors, which will take semiconductor test to the next level.

New Levels of Test Optimization

When conventional approaches for cost of test optimization – like capex reduction or increasing multisite – reach their limits, test cell solutions provides further gains in productivity. “Pin to pin signal ownership” ensures that test cells are able to significantly shorten time-to-volume and meet the requirements of fast ramping and fluctuating demands. Exploiting the opportunities from new packaging trends and disruptive technologies require fastest adaptation. Cohu’s integration and pre-validation services will free-up customers’ in-house resources and help them to strengthen their market position and provides a process for continuous optimization.

Phases for Test Cell Innovation

Based on well-accepted Plug & Yield program, the “Plug & Yield Test Cell” is a complete, pre-qualified and pre-validated test cell combining performance optimized elements for faster time-to-volume and improved yield. Looking ahead, the Connected Test Cell will focus on OEE and yield improvement, enabled by real-time data collection and analysis, predictive maintenance and fair-safe set-up features. The Smart Test Cell will increase the automation level of final test operation based on an adaptive, self-learning system.
