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.

A 4-step under-cart audit turns the S-680A reel scrap tape cutter into visible, audit-ready 5S and ESD housekeeping on every feeder cart.

A 4-step standardization turns stencil wiper rolls from a fragmented, jam-prone consumable into one matched specification across every printer brand.

A radial insertion machine that places capacitors, resistors, and inductors into PCBs at speed, replacing hand insertion and cutting mis-insertion defects.

A wave soldering machine that forms through-hole joints at volume for THT PCBs, with tunable flux, preheat and wave control for tin-lead and lead-free alloys.

Finger marks, warped pallets, and chain jitter quietly eat your wave soldering yield. A field guide to the consumables nobody budgets for — and the 50/90/100 matching method.

A hands-on restart and troubleshooting protocol for the S3010A radial inserter — verify safety, recalibrate setpoints, check sensors, then ramp with AOI verification.
