That's an even better idea, but is there a way in kicad to store lines on the comments layer within the footprint library? I can see why we wouldn't want to contaminate the silkscreen with backyards (oh, I meant courtyards).
Sure, no problem... right click on the artwork, edit/edit layer (current) :D There are 2 issues with that: 1) You have to do it for one item at a time 2) There are no comment layer which 'flips' to the other side like silk, paste, adhesive or mask. The first is really a no-issue since there are usually few lines... for the second thing you could use the adhesive layer (but that's an hack) or 'suggest' that, for example, the ECO1/ECO2 layer would be changed to ECO_Front/ECO_Back or some similar improvement in the layer setup.
You're doing good. I can't afford really big SCR's, and even if I could, no one is going to give me 30A of AC power. I'd probably blow the fuses
30A on 24VAC is not a lot (actually, its a 'little' water heater in this case). But amps *still* heat copper a lot. And that's not really big, they call it 'medium power' (look for the vishay 50RIA thing). It's a lot inconvenient because a) is essentially a thing screwed on the board with flying wires and b) you need a mos to trigger its gate (about 150mA of current for turning it on...)
off. And of course, by optical inspection, I'm assuming you mean something else than an eyemetric inspection.
I mean a CNC camera with stored how the board should look like, of course :D
What do you use for generating the artwork? I need to stick two transparencies on top of each other to avoid pinholes. And if I'm lucky, I get horizontal lines of toner going straight through the board, just asking for a nice cutter-job after the board is etched.
I cheat, I submit the gerbers to a board manufacturer :D:D at a pro level it cost *less* than hand doing the whole thing, and result are guaranteed. I hand produce only the occasional single side for throw away experiments.
You have some interesting footprints. Perhaps after Oyvind releases his generator script, you may make some 3d packades for them.
I don't use the 3d packages, actually :D BTW I'm trying to reduce the IPC specs to a latex doc and some sample code to spread the knowledge. -- Lorenzo Marcantonio Logos Srl _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
