What kind of materials should I used inside USB flash drive?

We are a office stationery brand which is not so sophisticated in USB manufacturing and design, so we outsource them. The quotation is not so pretty in unite price because of the high cost of raw materials, according to the explanation of the supplier. What kind of materials should I used inside USB?

The PCB will contain copper, of course, and probably some gold plating. The solder will be tin with 5% silver. The device lead frames may be tin-plated copper, or just tin, and some component leads may be iron. If there are connectors there may be brass (copper/zinc) or phosphor bronze (copper/tin) Inside the ICs there will be aluminum, possibly gold (though not on the silicon, they don’t play well together), and traces of other exotic metals.

What do we need to check before releasing a PCB design?

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?

Is it OK to bend a VIA in a Flex PBC?

On a Flex Printed Circuit (FPC) made out of Kapton polyimide, will anything bad happen if I put a VIA in a part of the FPC that has to bend? VIA size: 0.2 mm hole diameter in 0.4 mm copper diameter. FPC bend radius: 0.7 mm. Kapton thickness: 0.2 mm. Copper weight: either 2 oz or 1 oz (I haven’t decided yet)

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?
