Maintenance guide for selective soldering

Targeted Soldering

Selective wave soldering uses a movable precision nozzle that solders only target points on the PCB. Non-soldering areas never contact solder or flux.

Nozzle Features

Precision nozzles come in various diameters. A quick-change mechanism enables fast replacement, improving changeover efficiency for multi-product production.

Daily Maintenance

  • Clean solder pot surface dross using specialized tools
  • Clean nozzle residues to prevent blockage
  • Check flux reservoir level
  • Inspect tubing seals
  • Clean equipment surfaces

Weekly Maintenance

  • Check conveyor chain tension and lubrication
  • Clean exhaust filtration screens
  • Inspect temperature sensors

Monthly Maintenance

  • Calibrate temperature control system
  • Inspect heating elements
  • Test wave height stability
  • Check pneumatic components

Quarterly Maintenance

  • Commission solder composition analysis
  • Inspect electrical system
  • Deep clean furnace walls and belts
