Especially, surface mounting is steadily penetrating into industrial segments as a world-wide popular technical trend. Although exposure to high temperature is inevitable during soldering we recommend limiting the soldering temperature to low levels as shown in figure for the sake of retaining inherent excellent reliability. Atomospheric temperature( C) =resin suface temperature 240 210 150 60 sec. Within 10 sec. Within 30 sec. Time (sec.) Fig 6 (a) When employing solder reflow method Atmospheric temperature around resin surfaces must be less than 240 , not exceeding the time length of 10 sec. Recommend temperature profile Precautions on heating method When resin in kept exposed to high temperature for a long time, device reliability may be marred. Therefore, it is essential to complete soldering in the shortest time possible.
