ASIC Production Test

ASIC Production Test

At SWINDON the production test of the ASIC is a key component of what we do and is an important element in the process of providing high quality product that is reliable and free of defects. It is so important and critical to the quality of what we produce that we conduct all wafer probe and ATE in-house at our SWINDON facility.

  • Wafer and package level tests correlated
  • 100% Data log
  • Tri temperature test
  • Burn In

Design and Test – One Team

ASIC quality is primarily achieved when the design engineering department and the test engineering department are closely linked in order to deliver optimal analogue performance and maximum mixed signal test efficiency. Achieving high yields, while maintaining the high test coverage demanded by the users of Analogue and Mixed-Signal ASICs, requires substantial knowledge and expertise of Design for Test techniques (DfT).

Test Engineering Department

The SWINDON Test Engineering Departments provides our customers with a wide range of experience in the ASIC test environment which includes RF, mixed signal and digital coupled with pressure calibration over temperature.

Their primary aim is to ensure 100% on time delivery with high yield and industry leading low ppm failure rates by developing test software and hardware to facilitate medium to high volume production. Our engineers develop complex production test programs for optimum throughput to maximise coverage but at the same time keeping the test program to a minimum, in order to reduce the test cost per IC.

As one of many continual improvements, we have reduced the test time of Devices Under Test (DUT) but also increased test coverage. This in turn minimises the final device cost but maximises performance through quality. The result is a dramatic increase in product repeatability, yield and overall test quality with a vast decrease in field failure ppm rates.
