Category:PCB PCB Design Rules
Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

There is a PCB design completed by Altium Designer, for which I want to increase via sizes. But there are too much of them, and changing all of them one by one will cost a long time. Is there any w...(view more)
Standard carbon through-hole resistors is familiar to us, but there are of course other types like wirewound, metal film, metal oxide, etc which we are not familiar. The trouble is, how do you identi...(view more)

There is a 0.5mm through hole, and 1.5mm pad in my PCB, but the manufacturer told me the cost need to increase because it is difficult to fabricate. Why it is hard to fabricate?(view more)
