When engineers design PCB layout,beside some function ideas,they should consider copper line width and space,hole size and parts footprint etc to save manufacturing cost…When I get this PCB design,I found there are three 0.2mm vias, not like other 0.3mm vias. And some space almost 1-2mil,It is unreasonable. So I suggest engineer to change the design for saving cost. EzPCB is not only PCB manufacture in China and we don’t make PCB completely as customer’s file. But we will help customer to check the file is reasonable or not. EzPCB always concentrate on offering the best service for customers. If you have any PCB or PCBA question,please feel free to contact EzPCB.
