When used, soldering iron welding head can't direct contact with SMD LED lights, colloid, avoid high temperature damage to it. In addition, when the pin is heated to 85 ℃, to ensure that it is not pressure, so this time can't pressure caused gold wire broken.
above all, you know about whether patch LED diode of manual welding.
