PCB fast-prototyping service

As a Chinese hardware engineer, it is painful for me to wait one or two months for the PCB prototypes to be produced and assembled. And it really prevent us from product iterations in PCB.

The question is why it takes so long to manufacture several pieces of PCB but developing a software just take few days?

The answer is simple: it is like playing music with a band when we talk about software, but for the hardware, it is like coordinating an orchestra. It is true for all the manufactures around the word.



U2–Software dev


Orchestra–Hardware dev



Don’t worry, the hard-working Chinese people have solved all this by offering PCB fast-prototyping services.

Just send them BOM, GEBER  and NC DRILL files.

A four layer PCB with all the components assembled comes to us just in two weeks. And the quality is ensured by their testing facilities!
