Aluminium PCBs are quite popular, especially for applications where the total LED quantity and/or power is high (e.g. 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 receive the samples BOM of our PCBA factory. It remarks that PCB is FR4 Isola 370HR. What is this and is it reliable materials?
I’m making my first 4 layer PCB (1 signal, 2 GND plane, 3 PWR plane, 4 signal) with impedance control. How do you know what type of material to use? Is FR4 material ok for the 50 Ω and 90 Ω impedance?
In order to reduce the size of a PCB, I will probably have to use smaller SM components. I currently use mostly 0805 passives, and am thinking about going to 0402 or smaller. Apart from power dissipation considerations, any pitfalls I should be aware of when making the transition?

SMD soldering refers to the process of soldering surface mount electronic components to printed circuit boards. As electronic devices and PCBs have gotten progressively smaller,
As electronics shrank in size and cost, consumer product manufacturers pressed for similarly miniature and affordable components. This drive catalyzed the development of the printed
