Do modern LED lights use thermal vias?

I have a technical question about thermal management with mid-power LED diodes.Do you use thermal vias on the PC board anymore? Either under the LED diode footprint or even around the footprint? Depends on the application limits and cost targets.

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.

How do you usually organize SMT parts during PCB assembly?

Suppose one is hand-assembling a board with many SMT components. Unlike THT, SMT components are often not labeled. How might one keep small (<100) quantities of such parts properly organized during assembly? Are there particular tools? Storage devices? Methods?

At what frequency do PCB traces start to act as antennas?

Just interested in PCB design. I am wondering whether PCB traces start to act as antennas at some frequency. Anybody knows?

What is the difference between a prototype PCB and a production PCB?

My project have gone through from design, prototype to mass production after lots of discussion and adjustment. Now the manufacturer are making our products in their product lines. And I would like to know is there any differences between the prototypes in my hand now and the final products output by the manufacturer?
