The AC driverless led cob are connected to circuits directly

This is AC driverless led cob, which is no gold wire encapsulating technology. Lowing the risk of damage caused by pressure.

The AC driverless led cob are connected to circuits directly. 

Avoid the thermal resistance from sapphire substrate and insulation layer, improve thermal performance of the product. Current channels are the entire bonding pad, original transition is 1mil gold wire. Improve the ability of suffering high current shock .

All the AC driverless led is used by USA ASM die bonding machine

USA ASM wire welding and soldering machine

Japan Mushasi Powder Spoting

Japan Mushasi glue sealing machine.
