Site-To-Site Variation In Parallel Test


From wafer to system level test, parallel test execution delivers significant benefits, including reduced costs, yet it’s never as simple as that PowerPoint slide you present to management. An engineering effort is required to balance the thermo-electrical challenges that occur as you increase the number of sites to be tested, or the number of slots in a burn-in oven or system level te... » read more

Coping With Parallel Test Site-to-Site Variation


Testing multiple devices in parallel using the same ATE results in reduced test time and lower costs, but it requires engineering finesse to make it so. Minimizing test measurement variation for each device under test (DUT) is a multi-physics problem, and it's one that is becoming more essential to resolve at each new process node and in multi-chip packages. It requires synchronization of el... » read more
