Abstract:

At SMT assembly, flux outgassing/drying is difficult for devices with poor venting channel, and resulted in insufficiently dried/burnt-off flux residue for no-clean process.

Examples including:

  • Large low stand-off components such as QFN, LGA
  • Components covered under electromagnetic shield which has either no or few venting holes
  • Components assembled within cavity of board
  • Any other devices with small open space around solder joints
