Prototype PCB

Our prototype PCB services allow customers to get printed circuit boards of innovative features within short lead time. How to decide which PCB service to pick for your project? Generally speaking, we would recommend you pick PCB prototyping service for function test on new products before putting them into a full production. For further concerns on PCB prototype PCB and standard PCB. W To guarantee the prototype board quality, we follow the same standard as our standard PCBs production and manufacture it with the highest specification possible.
