An SPI machine ensures optimal solder paste deposition by performing high-resolution 3D scans (up to 10µm accuracy) to measure volume, height, and alignment on PCB pads. Advanced systems detect insufficient or excessive paste, bridging, and misprints, preventing defects before component placement. AI-powered algorithms analyze data in real time, adjusting printer settings to maintain IPC-7527 compliance. With speeds up to 20 panels/hour, it integrates seamlessly into SMT lines for automotive, medical, and 5G electronics. Eco-friendly modes reduce energy use by 30%, while predictive maintenance alerts minimize downtime. By eliminating soldering errors at the source, SPI slashes rework by 60%—transforming PCB assembly into a proactive, zero-defect process.

SPI Machine: Ensuring Accurate Solder Paste Application in SMT Assembly


An SPI machine safeguards SMT quality by performing 3D micron-level scans of solder paste deposits, measuring volume, height, and alignment with ±10µm accuracy. Detecting insufficient paste, bridging, or misregistration, it prevents defects before component placement. Real-time feedback adjusts stencil printers, ensuring IPC-7527 compliance and 70% fewer rework cycles. Integrated into high-speed lines, it boosts throughput for automotive, medical, and 5G PCBs. AI-driven analytics predict process drift, enabling proactive corrections. By transforming solder paste inspection into a precision-controlled step, SPI ensures flawless assembly—where perfection begins at the foundation.



Why an SPI Machine is Crucial for Preventing Soldering Defects


An SPI machine prevents costly soldering defects by inspecting solder paste volume, height, and alignment with ±5µm accuracy, catching errors like insufficient deposition or bridging before component placement. Real-time 3D scans and AI analysis adjust stencil printers mid-process, ensuring IPC-7527 compliance and 80% fewer rework cycles. By eliminating flaws at the source, it slashes scrap costs by 50% and safeguards yield in automotive, aerospace, and medical PCB production. Integrated with IoT for predictive analytics, it transforms solder paste application into a proactive, zero-defect foundation for SMT assembly—where precision today prevents failures tomorrow.
