ATE boards, substrates & qualification hardware
all in one place.
From wafer to final test, your hardware interface is only as good as the board beneath it.
SilTest designs high-performance test interface boards and substrates that deliver signal integrity, thermal stability, and platform compatibility without delays or rework.
WHY IT MATTERS
Poorly designed hardware adds weeks of debug time, costs thousands in retesting, and introduces errors that skew yield data.
Up to 70% of initial test setup delays are caused by hardware design flaws or mismatches between the device and the ATE platform. (SilTest internal study, 2024)
What
We Deliver.
Substrate Design
Our substrate design services cover the full stack, from mixed-signal routing to signal and power integrity analysis. Using MLO/MLC technologies, we deliver high-performance substrates optimized for manufacturability, noise isolation, and electrical performance across digital, analog, and RF domains.
ATE Interface Boards
Our custom load boards are engineered for stability under high-stress production environments. Whether for final test or system-level validation, we ensure tight control over thermal behavior, mechanical durability, and signal integrity across major ATE platforms.
Qualification Boards
Designed for stress. Built for endurance. We develop HTOL, burn-in, and reliability test boards that withstand extreme conditions such as high temperature and current. These boards are qualified for platforms like Advantest, Teradyne, Chroma, and NI, ensuring seamless test execution under long-term load.
