Selective Soldering

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.

For high-mix, low-volume THT soldering, fixtures and pallets are a hidden tax. Run the fixture-less fit test, then see how the S100B solders by recalled program instead of mechanical tooling.

For HMLV factories, through-hole soldering is the bottleneck: wave needs fixtures, hand soldering is slow. Run the Fixture-Less Solder Decision, then see how the S100B removes both.

Hand soldering THT is slow and uneven. Run the Selective Solder Audit, then see how the SO-300 targets only the joints that need it.

Full-wave soldering exposes the whole board underside. Run the Selective Solder Audit, then see how the S-SWL31 targets only the THT pads.
