Again, DipTrace here was by default more conservative than what OSH Park can manufacture:Īnd adding on to that, as an hobbyist it is very unlikely you’ll ever need traces smaller than 10 mil, even for fine pitch QFN or TSSOP packages, but it doesn’t hurt to set the parameters right regardless.įinally on the last tab, don’t forget to tick the box “check copper pour” which is disabled by default: The second tab is very important because you need to specify the minimum sizes. 20 mil is ridiculously small when you think about it (half a millimeter!). You can set the board clearance to 15 mil technically as it is what OSH Park requires, but I like the extra 5 mil buffer so it is set to 20 here.
To make sure you are respecting these rules, in Diptrace PCB Layout go to verification/ design rules.īy default, Diptrace tends to be more conservative than what OSH Park can deliver but there are few things to change: Minimum 15 mil keep-out distance from traces to the board edge.But before we send PCBs to the fab, we must design a board that complies with OSH Park specifications which are: That being said, they do take in Gerber files. I love Diptrace, but OSH Park doesn’t accept its native “dip” file format. In this short tutorial you will learn how to a export DipTrace PCB Layout for OSH Park.
A typical two layer board costs US$5 per square inch. They take orders for very small quantities of boards (minimum 3) and they are able to do this by taking small hobbyist projects and compiling them into a big batch. OSH Park is a PCB manufacturer tailored to hobbyists.
