Driven by its large installed base of mixed signal testers, STATS ChipPAC has a team of engineers with expertise in high volume mixed signal testing. This allows STATS ChipPAC to focus engineering resources on the development of techniques and technology to maximize the throughput and first-pass yields on mixed signal platforms. One such example is the 16 site test setup shown below for testing 16 mixed signal devices in parallel.
16 site mixed signal test setup at STATS ChipPAC Singapore with hard docking solution and easy access HIB changer
This illustration highlights a typical hard docking solution used for multi-site testing. This hard dock effectively fuses the test head and load board to the handler frame and eliminates any stray movement in the contact plane that could cause good devices to fail. Also highlighted in the photograph is an easy access HIB changer that gives the socket maintenance team quick and easy access to the test sockets thereby maximizing the effectiveness of cleaning while minimizing tester downtime.
