You select your vendor and then setup DRC to something above their minimums. That's easy to overlook as you adjust hole sizes. Be sure the ring created between the hole and the outside of the pad is in spec.

You can set that in Diptrace and apply to all vias. Also make sure the vendor can handle your via size. Just try to layout a process to stick with as you revise and recheck. There are 1.1 million items to check and double-check and you're still likely to make a goof. Nothing sucks so bad as paying $20 -$50 and then you can't get the component into the holes. You want to keep the hole size close but leave several thou clearance. Tinning the pads would be nice but I've not had issues without it.Ĭheck your component pins and be sure your drill sizes will work with them. I've had several smaller boards made with them and they are very nicely done and the wait is pretty short. Spin them around in space, flip them over, look through all the holes. When you have completed the design and exported the gerbers and drill file you can check how they will come out with a 3d gerber file viewer. Oshpark might be a problem for production items if you want any colour other than purple! I don't think those prices can be beat, the service is good, and by all accounts the quality is good to. You should be able to get your PCB software to export all of those.ģ) Drill sizes are normally specified in the hole size for the pads on footprints and vias.Ĥ) For five boards, especially prototypes, I would suggest. Also any cut outs and slots etc.Ģ) You need a separate gerber file for each layer and a drill file for the holes. 1) Yes fabrication gets you the holes, plated through, and the solder mask layers and the silk screen layers.
