Comparisions of   China PCB prototype and USA PCB prototypes and Small Orders

Advantages of China PCB Prototypes |PCB small order

Free Panel design, free stackup design
100% layout check prior to production
IPC Class 2 specifications
100% electrical test on all boards
Fully-finished PCBs with 2 solder-masks and 1 or 2 silk-screens as needed
Full finish on copper: HASL, RoHs, gold or silver .
Short lead time at normal charges.
Many technical options available
Many Materials options available

Disadvantages of USA PCB prototype |PCB small order

Panel design and stack up design charges needed
Not IPC standards for prototypes
Random e-test or no e-test for PCB prototype.
NO soldermask or no silkscreen with America or European PCB prototype/small orders
Long lead time or very expensive prices for quick turn.
Only one type of techincal option available
Only one one material option available.

You might think the expensive freight and long shipping times are disadvantages of China PCB.But in fact, the freight is very cheap to ship from China to all over the world, eg. DHL, UPS ,Fedex and airfreight around 60% discounted by comparison. Shipping time is only 3-4 working days.
