What it does
Unimicron makes printed circuit boards and the substrates that carry chips inside a package, including high-density interconnect boards, multi-layer and rigid-flex boards, and IC carriers such as FCBGA and FCCSP used to mount processors and memory. It also produces connectors and test-related equipment, alongside smaller unrelated businesses. The company is based in Taoyuan City, Taiwan.

Who it is priced against

What the diary watches
