Installation Instruction:
1.The front side is connected by gold wire bonding.The bottom side is welding or bonding.
2. The back side is bonded with conductive adhesive or welded with solder paste below 320 degrees.
Usage Precautions
1. Storage Conditions: It is recommended to store in a constant temperature and humidity warehouse.
2. When manually welding the lead end, a constant temperature soldering iron ≤350℃ should be used, and the welding time should be controlled within 5 seconds.
3. The front electrode port should be bonded with gold wire.
4. To meet the derating curve, install a radiator with a large enough size. Solder paste should be sintered between the metal surface and the radiator, and the solder should melt for less than 5 seconds. Add air cooling or water cooling if necessary.
