In PCB field, WIP (Work in Process) are partially finished printed circuit boards (PCBs) or PCB assemblies (PCBAs) being fabricated or waiting for further processing in queue under the roof of a turnkey PCB assembly manufacturer. With the management of PCB fabrication process and PCB assembly process, both a customer and a supplier can instantly monitor the progress of the product, and can ensure on-time delivery.

At MADPCB, the planners are responsible for work-in-process updating. we can feedback customers where the process of their product is in at any time when at request. When there are tens or hundreds of different fabrication model numbers in the fabrication lines, the importance of WIP management is obvious.
