Selective Soldering Process - Recommended Parameters

Download pdf version

Solder Temperature

• Measure and verify regularly that the set solder temperature is stable.
  Recommended: Check every 2 weeks.

Preheater

• Measure and verify regularly that the set temperature profile on the top and bottom of the PCB is stable.
  Recommended:  Check every week or every time you change a product over.

Flux

• Check the flux quality. Since only a small amount of flux is used for selective soldering, make sure the flux has not expired.
• Make sure maintenance is done on the Spray Fluxer.
• Make sure the Fluxer is spraying correctly.
  Recommended: Should be checked every shift.

Nozzle

• Monitor wave height
  Recommended: Clean wettable nozzle 2 to 3 times per shift.

Position of the Board

• Make sure the PCB orientation is always the same when loading the machine.

Board Warping

• A heavily warped board cannot be controlled by the selective soldering machine.
• Make sure the board is as even as possible.
• If necessary, use special solder fixtures.
