Field notes from Jason Wu — 30+ years of hands-on THT auto insertion experience. Articles on custom-designed SMT & THT machines, odd-form feeding, wave soldering, and spare parts for future-proof, cost-effective EMS production lines.

Odd-form parts still get hand-placed at the end of the DIP line. Run the Odd-Form Audit, then see how SOLVE-10 automates 10 types.
A synchronized input conveyor that feeds PCBs and pallets into the wave solder inlet at a steady, adjustable rate, replacing manual loading at the THT line.

Full-wave soldering exposes the whole board underside. Run the Selective Solder Audit, then see how the S-SWL31 targets only the THT pads.

The operator's wage is visible; the rework, scrap and field returns from hand insertion are not. Run the Odd-Form Cost Audit first.

Axial resistors and diodes are the backbone of power supply and LED driver boards — and the last step still done by hand.
Residue you cannot see becomes leakage current, dendrite growth and coating failure months later. Clean it at line speed instead.
