Test Equipment Engineer
Test Equipment engineers work with Test floor operations to manage daily life on a test factory floor. While the latter person oversees the plan, the test equipment engineer manages the flow of product through the test cells under their charge. They instruct operators on reconfiguring test cells with the appropriate ATE, handler/prober, loadboard/probe cards and test programs for a specific product or set of products that can use the same test cell set-up. Depending upon the scheduled test floor activities that configuration may last for hours or weeks.
Another responsibility is assuring that the correct version of a test program has been applied. For a product with sufficient volume multiple test cells can run in parallel. Test equipment engineers want to know if statistically significant yield differences exist between test cells. Statistical Bin Limits or Statistical Yield limit alerts provide the warning and the ability to dig deeper in the data using commonality analysis may reveal a problematic ATE or probe card has issues. Such issues often require maintenance and the rapid response to such issues will positively impact the profitability and overall schedule of product heading out the door.
