Yamaha YSi-SP 3D Solder Paste Inspection Machine

The YSi-SP inspects solder paste for volume, height, area, and misalignment. It uses a combination of 2D and 3D measurements, with image resolution switch-over for high-accuracy inspection.

It handles PCBs from 50 × 50 mm up to 510 × 460 mm (single-lane spec), with board thickness between 0.3 mm to 5.0 mm.

The machine offers selectable horizontal resolution modes:

• 25 µm / 12.5 µm (≈ 50×50 mm)
• 20 µm / 10 µm (≈ 40×40 mm)
• 15 µm / 7.5 µm (≈ 30×30 mm)

All modes support high precision for small area inspections. Vertical (height) resolution is 1 µm.

It supports automatic setup changes via upstream data (barcodes or PCB IDs), can feed back print misalignment metrics to the printer, convert dispenser coating inspection data, and also send “bad mark” data forward to downstream mounters. This reduces redundant checks and helps maintain consistent quality.

Yes—the YSi-SP includes SPC capabilities to perform statistical analysis of measured paste volumes, heights, misalignment, etc. This helps manufacturers monitor quality trends and identify issues early.

The YSi-SP has dimensions of 904 × 1,080 × 1,478 mm (L×W×H), weighs about 550 kg, and runs on single-phase AC 200-230 V ±10%. It does not require an air supply (airless specification).

Optional packages include bonding inspection, foreign matter inspection, image resolution switch-over, and dispensing-coating inspection conversion. These allow you to tailor the machine for special inspection tasks beyond standard paste metrics.

By using the YSi-SP, defects in solder printing (volume defects, misalignment, excessive or insufficient height) can be detected early—after paste printing but before component placement. This prevents downstream failures, reduces rework, improves yield, and helps ensure consistent solder joints. The machine’s high speed + high accuracy helps manufacturers catch issues without slowing line throughput significantly.
