We was simply in PCB production before, while during our cooperation with our customers, we found even we send our boards in time, customers might still can’t push their project as scheduled, and loose the best time for marketing. More and more of them purchase more parts from China, while sometimes they can’t control well for other of their suppliers, even sometimes will out of control. They are not able to come soon or even start branch in China. They waste a lot of time on discussing, waiting for response or complaint to many different suppliers; they can’t tell if the parts are really good, or can match each other before having in hand -  we can do this – we can help to check all parts and assemble them based on your instruction, to save time and delivery cost when some parts should be rejected.
