Chunghwa Precision Test Tech. Co., Ltd. — AI supply-chain exposure

Chunghwa Precision Test, part of the CHT group, builds high-end vertical probe cards and the test interfaces around them for advanced-node logic. Its cards make the delicate electrical contact with a wafer during probe test, and its focus is the leading edge — the foundry and high-performance-computing chips whose pad counts and pitches are hardest to contact reliably.

The hook is specialization at the demanding end of test. Vertical probe cards for advanced logic are a high-barrier niche: as AI and HPC parts carry more pins packed at finer spacing, the card must contact more points with tighter tolerance, and few vendors can build them well. That anchors demand to the same leading-edge logic that sits at the centre of the AI build-out. The model reads Chunghwa Precision Test as a supplier whose relevance grows with node complexity — a small but specialised link feeding the test step that every advanced chip must pass.
