How is the panel separated after assembly?

I need to design LED tube PCB and is only 20mm wide, so there will be at least 10 pieces next to each other on one panel. The assembly house warned me, that it is not the same to separate these as it is with standard PCBs. How are these made to be separated?

You can have them milled and V-grooved in a similar way to the way it is done on FR4 PCBs.

The edges where they are separated from where the V-groove was will not be smooth, the other edges will be smooth.

If you require all the edges to be smooth you can have them milled out entirely and insert them into carriers for assembly.

What Others Are Asking

How do I know whether a food safety device samples is good in quality?

I order the first one food detect device to a PCB factory, but they gave me the one in darker color than the pictures shown online. Does it often mean the PCB inside has poor quality? How can I check it?
