Aluminium PCBs are quite popular, especially for applications where the total LED quantity and/or power is high (bijv. COBs).
Aluminium is used as the substrate, and the PCB tracks are isolated from it. Different materials are available for different isolation requirements.
This aluminium PCB can be directly attached to the heatsink.

I’m designing a PCB right now and found out I can save a lot of space using the back of THT elements. Is it legit to design like that? Are there any problems that might occur?
Recently we are developing a portable device which should be very tiny and light. In terms of PCB design, I am thinking whether it is a good idea to exclude ground plane to minimize the product size.
I have a set of LED driving lights for motorcycle that must be wired through a ground-leg pulse width modulation dimmer. The problem is the mounting bracket for the lights is grounded, so the lamp shorts to ground through the motorcycle chassis and the PWM dimmer cant dim the lamps. How do I handle this problem?
