Pre-Print PCB Contamination Is a Hidden Yield Killer on SMT Lines
A particle on a bare board becomes a printing defect downstream. Run the Pre-Print Cleanliness Audit, then see how the sticky-roller cleaner removes it inline.

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 particle on a bare board becomes a printing defect downstream. Run the Pre-Print Cleanliness Audit, then see how the sticky-roller cleaner removes it inline.

Manual brush cleaning is hard to standardize. Run the Post-Solder Cleaning Audit, then see how the SME-350MB cleans boards inline.

Most SMT defects start at printing. Run the Print Accuracy Audit, then see how the SP-1008 lays paste precisely every cycle.
A compact SMT unloader that lifts boards off the line and corrects tilt automatically, freeing an operator at the end of a crowded SMT or FPC line.

Manual harness prep is slow and inconsistent. Run the Harness Prep Audit, then see how one machine cuts, strips and crimps.

Manual reel counting costs hours and invites miscounts. Run the Reel Count Audit, then see how X-ray counting targets a 10x cost cut.
