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 400 x 250 mm LED driver board with both axial and radial components, quoted in Serbia in two days. The capital configuration was the visible half. The carrier clips were the half that decides whether the machine runs i
A rotary table motor drive failed on an axial insertion machine in the British Isles. The customer could not identify the board. We diagnosed it from the symptom description, without a site visit, inside six years of sha
Axial resistors, diodes and capacitors are still inserted by hand on many THT lines. Run the four-failure-mode feed check, then see how the ATF-1002 feeds taped axial parts to your existing inserter.
Axial resistors and diodes are the backbone of power supply and LED driver boards — and the last step still done by hand.
The S4000 axial inserter accepts tape-packed resistors, diodes and jumper wires within defined lead diameter and span limits.
A THT auto-insertion station that places transformers, rectifiers and capacitors on LED power boards with machine consistency, then links into your wave-solder line.
