Why are PCB-mount AC DC converters so expensive?

I got the PCB quotation sheet and price breakdown from supplier. The unit price is not so pretty due to AC DC converters with outstanding high price, comparing to the PCB I employed wall wart. Is it normal?

The main difference is that the volume of production for board-mounted AC-DC converters is very low, so you pay a boutique price.

Decent quality fully approved (safety and EMC) wall-wart adapters are made in huge volume so the costs are relatively low.

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?

How do I determine the traces width when designing a PCB?

Our team are developing a portable medical device with a small size, so we need a small PCB. How do I determine the traces width when designing a PCB? Actually we want it as narrow as possible to fit the device, is it OK?

Can I use LEDs without PCB?

I recently purchased LEDs on ebay that were supposed to come attached to star PCB (as a heat sink). The items I received are just the LEDs (no PCB). They are listed as 3W LEDs, with a forward voltage of 3.0-3.4V, and current at 700mA.Will I damage/destroy the LEDs if I use them without a heat sink? If not, what is the best way to mount these to preserve their life during operation?
