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.

After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?
I mean, headphones or ear buds are capable of reducing the ambient background noise. Can it realize by circuit design or other approaches?
We receive a batch of PCB with scratches from my supplier, but they think it is acceptable. I have never seen such error on even an B stock boards parts. Very confused. How do scratches affect PCB working?
