Process Control

Every THT board that crosses a Wave Soldering machine is carried by its edges on conveyor fingers — the claw-shaped links that hold the PCB through fluxing, preheat, the solder wave and cooling. They are among the least expensive parts on the line and among the most decisive: worn or corroded claws change board flatness, wave contact and solder bridging. This guide from Southern Machinery covers titanium claws and resin claws — what they do, how to choose between L and V profiles, what to confirm before ordering, and how the consumable fits a complete SMT/THT PCB assembly line.

Dirty, clogged stencils are a silent yield killer in any SMT line — dried solder paste and red glue inside apertures cause insufficient-paste, bridging, and tombstoning defects that cascade into placement and reflow. Sou

The SME800 electric stencil cleaner from Southern Machinery removes paste, adhesive, and mask residues from stencils and misprinted PCBs for higher SMT yield.
