No, I would not rely on a solder mask as an insulator, because it is very thin and can be nicked easily.
The key issue is going to be how to properly heat sink the LED without a good thermal connection to the heat slug. High-power LEDs usually want the heat slug soldered or thermally epoxied to a heatsink. This can be PCB copper, but since you stated that the PCB copper is connected to the GND net you can’t connect to it.

This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn’t you use a through hole connector?
I am designing a PCB with 1088 pin BGA IC. Haven’t handle such a big IC. I am not sure the best amount of layer.
I ordered RF PCB design and prototype from my supplier . There are something like a hole, but it is not, on the ground surface. What is the purpose of making these holes? The PCB is inside of the E70 433NW14S LoRa module.
