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 Others Are Asking

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (thus, higher temperature) process?

How does the PCB regulate the dimming of solar energy light?

I often design dimmable light, but never handle that power by solar energy. Could you please tell how to realize it. I think now we need to follow the environmental-friendly trend and launch some green electric products.
