For ease, nothing beats the iron-on transfer method. You can use glossy ink jet paper, laser print the layout on it and iron it onto the copper-clad. It takes a bit of finesse but once you figure it out you can get pretty fine traces on there consistantly. The light-sensitive transfer methods work too, but the boards are more expensive... As far as drilling holes? Use a layout program that will put a hole in the pad for you, then your drill just slips in and you can't possibly make a mistake without trying. I use a Dremel with tiny bits, but a normal drill would work too. For layout software, I highly recommend Eagle (www.cadsoft.de). Their trial version is fully featured, doesn't expire, or nag. Just has a size and quantity limit for boards, which is almost always big enough for hobby projects. It has an autorouter, etc... Very nice for what it is. Learning curve isn't sharp at all either. nick@veys.com | www.veys.com/nick > -----Original Message----- > From: pic microcontroller discussion list > [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Pic Dude > Sent: Wednesday, March 06, 2002 11:48 AM > To: PICLIST@MITVMA.MIT.EDU > Subject: [EE]: Making PCBs... > > > Couldn't find a good answer to this in the archives or web, so... > > Trying to figure out how to make professional-quality PCB's > at home.
