Key Nvidia and Intel supplier raided over alleged China origin fraud — Unimicron faces probe over PCB origin washing, risk of 40% U.S. tariff penalty

Unimicron, a major PCB and chip substrate supplier to Nvidia, Intel, Google, and Amazon, is under investigation in Taiwan for allegedly shipping China-made PCBs to Taiwan, relabeling them, and selling them as Taiwanese products. Prosecutors raided its HQ and plant, questioned 14 suspects, and set bail. The case could trigger U.S. Customs' 40% transshipment penalty on qualifying imports, though the involved products appear to be conventional PCBs rather than advanced ABF substrates.
