NVIDIA and AMD have continued to expand their share in the high-performance computing market in the past few years, and their semiconductor test interface supplier TWYW has also continued to expand in the logic IC test socket (Test Socket) market.
"Each probe is as thin as hair! The CTO of TWYW showed us a flat box smaller than a slap. Inside, there are densely packed and densely packed probes made by TWYW. These small probes require a magnifying glass. It can be seen clearly that these probes control the chip yield for IC design customers. Whether the chip is qualified or not can be shipped only after passing the test.
Whether a GPU (graphic display) is a good product or not, an IC test socket is required to connect and test. There are thousands of pins on the test socket. The pins are made of gold and palladium alloys. The precision is high. The four parts are grouped together, and the working error is in the um level. These probes can be connected to the solder balls under the chip to test whether the chip is normal. If one probe is damaged, the entire test socket cannot be used.
What TWYW does is the chip vertical test probe card before chip packaging, and the business of "final test base" and "system test (SLT) test base" after chip packaging, which accounts for 60 to 70% of the revenue. At present, TWYW has rushed to the world's third place in the ranking of global logic chip "test seat" companies. The first is American Cohu, and the second is Japanese manufacturer Yokowo. The latter is also an outsourcing partner of TWYW probes.
From 2018 to 2019, TWYW will set foot in the Burn In Socket. This business is mainly to help customers do chip burn-in testing. This is a very critical link for high-wattage chips or automotive chips, because the chip must be When the environment is often high or low temperature -40 degrees, the aging test can ensure the quality.
TWYW currently needs 2.5 to 3 million probes per month. Now its self-production is only 500,000, and it is estimated to expand to 1 million by the end of 2021. The self-sufficiency rate is 30%. TWYW hopes to increase its self-sufficiency rate to 50%. It has announced an investment of 2.1 billion yuan to build a new plant and mass production in 2023.
Starting from the first graphics chip, TWYW has worked closely with customers such as AMD, NVIDIA, Qualcomm, Broadcom, and leading American electric vehicles.
