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.
Seven product lines moved through one Mexican distributor in nine months. The orders were the easy part. What converted them was drawings, manuals, localised collateral and two weeks of hands-on training in China.
After the wave, the pliers come out: manual THT lead trimming is the step most line charts leave out, and it is where yield quietly leaks away. Here is how an inline auto lead cutter closes the gap.
When misprint rates climb, the printer gets blamed first and the stencil gets wiped harder. But most of the time, the apertures were already blocked before the board ever arrived.
Two radial inserters, two automation levels. Use the five-parameter check to decide between the S3000 entry model and the S3010A inline cell before you ask for a configuration.
Every hand-soldered joint is a quality lottery. The S-C5331R and S-HX331R move that variability from the operator to the machine — here is how to pick between them.
Choosing a BGA rework station is an envelope problem, not a catalog problem. Match board size, package pitch and monthly rework volume to the SM-650, the SR-430A or an S-B value station.
