Overview
Micronics Japan is headquartered in Musashino, Tokyo. Its U-Probe uses MEMS micro-cantilever probes on thin-film multilayer substrates to test DRAM and flash memory dies on 12-inch wafers, covering about 2,500 DUTs with about 200,000 pins in one touchdown.
Business: Probe cards
Why it matters
Probe cards are the consumable that connects the tester to every die on the wafer, and memory wafer test depends on massive parallelism.
