Homebrew PCBs

Thanks for the replies.  I have several sharpies in my desk drawer.  Unfortunately, since my last post, I noticed another issue.  I don't have a laser printer here at home, so I printed the layout to a file and loaded it to my jump drive for a remote print.  I discovered that the resulting printout from the file shrunk the layout a bit.  The mounting holes no longer line up, and everything is squeezed together accordingly.  It wasn't immediately apparent due to the small difference, but when compared side by side with a printout from my home printer through the PCB software, it seems to have shrunk maybe 5% or so.  Looks like I will have to try the transfer again, printing it out on my printer on some good paper, then borrow a copy machine to make the transfer.

Subject: Re: [Homebrew_PCBs] Toner transfer touch-up?


Hello Nels,

I've had reasonable results using a Sharpie Permanent Marker to fill 
in toner transfer voids.  They can be obtained at just about any 
store including larger grocery stores.  I've found them with a fine 
tip at one end and a "ultra fine" tip at the other.  Makes it nice to 
have both tips on a single pen.

Sometimes when a quick board with a small amount of components for a 
home project is need, I just draw it on the PCB with the 
pen.  Electrons don't care if the lines have size variation, etc.
