CST Global introduces real-time electronic barcode tracking of all work in progress

Compound Semiconductor Technologies Global Ltd (CST Global) of Hamilton International Technology Park, Blantyre, near Glasgow, Scotland, UK (a subsidiary of Sweden-based Sivers IMA Holding AB) has introduced real-time, electronic barcode tagging for all work in progress (WIP) in its III-V optoelectronic foundry. “Our laser production now exceeds 1 million per month, so managing production electronically is essential,” says senior production engineer Meg Armstrong. “A barcode is allocated to each wafer when it is released to our production line and becomes a ‘lot’. This barcode is used to track the lot, containing up to 100,000 lasers, as it progresses through the production line to finished goods."
