  • Solder bumps are melted in vacuum so that the foams (void) in the bumps can be eliminated.
  • The heater stage is provided with a quenching mechanism, which shortens the reflow time and enables post-reflow quenching so that excellent reflow conditions are attained.
  • Equipment is automated so that 6 or 8-inch wafers can be processed in a cassette-to-cassette manner.
