Pad sizes using EagleCad and a late night office experiment

2004-01-07 by joshdewinter

Hi guys.
  Thanks for the suggestion Marc.  That drilcfg.udp utility is 
handy.  I guess I should have gotten my terminology straight when I 
wrote that...I'm thinking more of enlarging the copper pad that I 
would solder to, rather than the drilling hole.  You don't know of a 
way to do this effectively in Eagle by any chance do you?  The pads 
it makes are just plain tiny.  If you have a good drill, this is 
great, I'm using a Dremel by hand, which can be a little harder to 
eyeball than a nice drill press.

  Note...Last night I happened to come across something that was a 
little like the discovery of penecillin to me...I was experimenting 
with different materials, and put an antistatic bag through our 
laser printer at work...the bag got stuck and created a paper jam.
  When I opened it up, I found that it hadn't been crinkled into a 
little ball, but had just quit moving...right after the toner 
transfer stage, but before the fuser.  I had a nice, slipery 
surface, covered with toner that was clinging to the paper, but was 
still in it's unmelted, powdery form, and hadn't been fused yet.  I 
immediately ironed it to a board, and with very little pressure it 
seemed to work very well.  I'm wondering, why not try to trick a 
laser printer into thinking its fuser is present and up to temp when 
it's really been removed?  That would give us toner that perhaps 
wasn't as hard to transfer.  I'm still experimenting...
