Be careful that flux does not overflow onto the PC board or penetrate inside the relay. 2. Soldering We recommend the following soldering conditions. 1) Automatic soldering * Preheating: 100C 212F, within 2 mins (PC board solder surface) * Soldering: 260C 500F, within 5 s 2) Hand soldering * Iron tip temperature: 280 to 300C 536 to 571F * Soldering iron: 30 to 60W * Soldering time: Within 3 s For Cautions for Use, see Relay Technical Information. ds_61B13_en_lk: 010611J 3
