Hello,
I have developed a high power UV-LED Array. Total loss of the PCB is about 200 Watts. The PCB is made from Aluminum and installed on a big heat-sink. The heat-sink is cooled with a high power FAN.
Unfortunately I can't cool down enough with the aluminum PCB. It can't transfer enough heat. I thought about using a ceramic PCB. Does anyone have experience with ceramic PCBs?
How are they attached to the heat-sink? Can I use screws?
Which type of thermal material is used between the PCB and the heat-sink?
Another question: Is there a way to manufacture an aluminum PCB directly on a heat-sink?
Regards,
Ersin
