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.
Your placement head only runs as fast as its material supply. Run the Tray Fit Audit, then see how a custom Southern Machinery tray feeder keeps QFP/BGA/LGA/CSP and odd-form parts presented without manual swaps.
Most PCB defects are born at the stencil. Run the Tension Rule, then see how a mesh tension meter catches a failing stencil in 10 seconds — before a single board is printed.
For tube-packaged ICs, LEDs, and connectors, the bottleneck is often the operator refilling the feeder. Run the 40-Tube Throughput Test, then see how the STF-1002 stacks 40 tubes and presents them hands-free.
On a mixed SMT/THT line, the bottleneck is usually the manual odd-form station. Run the Odd-Form Bottleneck Audit, then see how the S7040 automates transformers, relays and connectors.
A long-platform V-cut separator that singulates LED tubes and panels up to 1200 mm cleanly, replacing hand-breaking on the SMT and LED floor.
When AOI or SPI rejects a board, the line should not stop. Run the NG/OK Buffer Check, then see how the SBN250 stores 12 PCBs and decouples takt time on your SMT/THT line.
