(3) After soldering,do not warp the circuit board. (4) The encapsulated material of the LEDs is silicone. Precautions should be taken to avoid the strong pressure on the encapsulated part. So when using the chip mounter,the picking up nozzle that does not affect the silicone resin should be used. Hand Soldering Conditions: Do not exceed 3 seconds at maximum 320°C under soldering iron.(one time only) Page 5/10 LIGITEK ELECTRONICS CO.,LTD.
