What this manufacturer makes
Unistar Electronics manufactures printed circuit boards in Kunshan, Jiangsu. Its official company history dates the operation to 2003 and describes service to automotive, industrial computers, wearables, medical equipment and computer peripherals. The website presents high-layer-count rigid boards alongside HDI, blind/buried vias, high-frequency/high-speed work and filled-via processes. This profile records the rigid multilayer family. Each special process must be reviewed against the proposed stack-up rather than combined automatically into one manufacturing promise.
