I.C.T, a global SMT equipment provider, today announced a contract manufacturer achieved 98.7% first-pass yield on high-mix PCB lines using the I.C.T-5151 solder paste printer integrated with real-time solder paste printing data analysis.


The facility, producing 60,000 boards monthly for medical and industrial clients, previously suffered $22,000 rework costs from 14% paste volume variation on 0201 components. Root cause: undetected stencil wear and humidity-induced viscosity drift.


Post-installation, the I.C.T-5151's 3D SPI measures height, area, and volume per pad. YOLOX-based defect detection delivers 90.3% accuracy. When RH reached 62%, the system auto-adjusted squeegee parameters, stabilizing volume std dev at 3.8%. Bridging defects fell 72%.


Machine learning analyzes 150,000+ prints to predict stencil cleaning at 12,200 cycles, enabling planned maintenance and zero unplanned downtime. Stencil consumption dropped 48%; cleaning solvent use declined 42%.


Operators completed two-day on-site training; lead technician Maria Lopez noted, "Alerts now guide corrections before defects propagate."


An independent audit by a drone OEM confirmed live TE dashboards and increased monthly volume 28%.
