Critical Manufacturing provides a modern MES platform for semiconductor, electronics, and medical device manufacturers requiring complex process control and traceability.
About
Critical Manufacturing is a manufacturing execution system vendor headquartered in Porto, Portugal that develops and deploys MES software specifically designed for the high-complexity, high-regulation manufacturing environments found in semiconductor fabrication, electronics assembly, and medical device production — industries where the volume of process steps, the granularity of traceability requirements, and the complexity of equipment automation interfaces exceed the capabilities of general-purpose MES platforms. The company was founded in 2009 by executives with deep MES implementation experience in the semiconductor industry and has built a product architecture that natively handles the characteristics of advanced manufacturing: lot genealogy tracking across hundreds of process steps, complex routing logic including re-entrant processes where the same equipment is used multiple times at different manufacturing stages, and real-time equipment integration for automated dispatch and data collection from semiconductor process tools.
