The Challenge
Non-destructive reconstruction of proprietary industrial control PCB designs for legacy system modernization and supply chain diversification
Context & Background
IndustrialControl Systems operates 340 manufacturing facilities worldwide with proprietary control PCB designs dating back 15+ years. These mission-critical boards control everything from assembly lines to chemical processes. Original schematics and manufacturing files were lost during corporate acquisitions and supplier changes. Each PCB contains 12-28 layers, 2,000-8,000 components, and controls processes worth $2.3B in annual revenue. Plant downtime due to PCB failures cost $47,000 per hour.
Business Impact
The lack of design documentation created dependency on single-source suppliers, vulnerability to supply chain disruptions, inability to implement improvements, and escalating maintenance costs averaging $12.3M annually across all facilities.
