Wafer level testing
Wafer level packaging (WLP) is a technique which will, in the near future, change the MEMS sensor market tremendously. Especially in the field of consumer electronics WLP –products will substitute a lot of the traditionally packaged sensors.

Strip/Lead frame level testing
Decreasing component prices set also pressure to the testing costs. One way to response to this is to perform the testing in strips or lead frames. Testing of multiple components simultaneously gives high throughput and thus declines investment cost.
In addition, strip/lead frame level testing gives other benefits. Since the components are getting smaller and smaller, the positioning as a singulated component is very difficult. In case of motion sensor this may cause tremendous cross axis errors during testing. Positioning of a strip or lead frame is more accurate, which gives better testing results.
Afore offers two handlers for testing of low-g accelerometers and gyroscopes: Metis for ambient temperature testing and Zeus for tri-temp testing. Please find more information by clicking the links beside.
