Elements mounting styles of electronic devices are gaining in further diversification over recent years, and needs for components are all the more expanding in varieties. 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. 1. When employing solder reflow method 1) Soldering Condition Standard Condition : 250 (Temperature), 10 1sec. (Time) Peak Condition : 260 3 2) Recommend temperature profile 3) 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 to prevent temperature of resin from rising. 2. When employing halogen lamps or infrared-ray heaters When halogen lamps or infrared-ray heaters are used, avoid direct irradiation onto resin surfaces; such devices cause extensive localized temperature rise. Please keep a reflow solder operating when Surface Mount Package s Soldering. [Lead-Free Soldering Temperature Profile] 20~40sec 60~180sec 200℃ 217℃ 60~150sec
