Capabilities

WellPCB is focusing on online prototype orders to meet the requirements for High Quality, Low Cost, Fast Delivery, Easy Ordering from customers around the world. We can accept 4 kinds of files format (Gerber, .pcb, .pcbdoc or .cam file format) for PCB Prototype Manufacturing.

 

We perform full DRC checks of all Client files and inform you immediately if we find any problem. We then will work with you to correct the files, so they are suitable for manufacturing. Please check our capability overview below for reference. Please contact us if you have a special requirement not listed in the following table.

pcb ASSEMBLY

We strive to make the whole assembly process as easy as possible:

Single Point Source: No need to order bare board PCB from one supplier, solder stencil from another supplier, and PCB assembly from yet another supplier.

We provide prototype promotions and also mass quantity production from one board to thousands of boards.

We offer a rapid turnaround, kit service, turnkey service, harness assembly, and box build service.
