PCB is customized products, that is to say, there will be no stock. It will take some some time for the PCB board completion, which includes many process. 

Engineer will work on the cam process and work on MI, which takes about 2 hours for doubled sided PCB and 4 hours or more for multilayer PCB cam process. There many process for a PCBs, drill, PTH, plating, soldermask, surface treatment, e-test, routing, and QC. Standard turnaround for 2 layer will takes about 5 days and 8 days for multilayer PCBs.

Linked Electronics understand that for some customers, there might be some urgent needs for some PCB Board. And we specialized the quick turn around PCB for more than 1 decades.
