Nie, 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.

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.
I’m making a 4 layer PCB prototype that uses a bluetooth mcu connected to a 2.4GHz chip antenna. I’m thinking about what to do with the feedline, whether it should be buried on one of the middle layers, or left on the top layer. To get a 50 om linia, should I choose top layer with 13-mil width or buried miccrostrip with 7-mild width?
Niejednokrotnie nasz producent PCBA dzwoni do nas w sprawie problemu z plikiem projektu. Czasami wydaje nam się, że omawianie tej kwestii jest czasochłonne. Chcę tylko wiedzieć, dlaczego zawsze to robią.
