PRECAUTION
SOLDERING
Fiat Package (SOT-89 Package)
Elements mounting styles electronic devices gaining further diversification over recent years, needs components more expanding varieties. Especially, surface mounting steadily penetrating into industrial segments world-wide popular technical trend. Although exposure high temperature inevitable during soldering recommend limiting soldering temperature levels shown figure sake retaining inherent excellent reliability.
Time (sec.) Within sec.
Within sec.
When employing solder reflow method
Atmospheric temperature around resin surfaces must less than exceeding time length sec.
Recommend temperature profile
Precautions heating method
When resin kept exposed high temperature long time, device reliability marred. Therefore, essential complete soldering shortest time possible prevent temperature resin from rising.
When employing halogen lamps infrared-ray heaters
When halogen lamps infrared-ray heaters used, avoid direct irradiation onto resin surfaces; such devices cause extensive localized temperature rise.
Please keep reflow solder operating when SOT-89 package's soldering.
