3D SPI Solutions for High-Yield SMT Lines Stop Solder Paste Defects Before They Kill Your Yield
What Is SPI and Why It’s Critical for SMT Yield
Detect, prevent, and control solder paste defects in real time.
Improve first-pass yield, reduce rework, and enable closed-loop SMT process control.
✔ Detect insufficient, excessive, bridging, and offset defects before reflow
✔ Improve first-pass yield (FPY) and reduce costly rework
✔ Enable real-time closed-loop control between SPI and printer
✔ High-precision 3D inspection with stable and reliable detection
✔ Accurate measurement of height, volume, and area
✔ Seamless integration with SMT line and MES system
Where is SPI used in an SMT line?
SPI sits right after printing—where yield is decided.
It controls quality at the source, not after defects happen.
With real-time measurement and closed-loop feedback, SPI reduces rework and keeps production stable.
From standard production to high-precision applications, I.C.T-S510, I.C.T-S510D, and I.C.T-S1200 deliver the right level of inspection performance for every SMT line.

SPI System Breakdown: How It Ensures Stable and Accurate Inspection
SPI is not just an inspection machine — it is a data-driven control system for your entire SMT process.
🔹 Vision System: Accurate measurement with minimal false calls
🔹 Platform & Motion System: Stable performance without drift over long production runs
🔹 Transport System: Smooth inline operation with reduced downtime
🔹 Control & Software System: Data-driven control instead of guesswork
Closed-Loop Control: From Inspection to Optimization
Inspection alone isn’t enough—the real value is using data to control the process.
🔹 SPI inspects solder paste height, volume, and alignment in real time, catching defects immediately after printing.
🔹 Inspection data is analyzed through SPC to reveal process variation and stability trends.
🔹 Real-time feedback to the printer enables automatic adjustment and continuous process optimization.
Common Solder Paste Defects SPI Can Detect
Solder paste printing defects are one of the leading causes of SMT failures. SPI helps detect these issues early, preventing them from affecting placement and reflow processes.
