These guys have tons of information and mis-information. > http://groups.yahoo.com/group/Homebrew_PCBs Do it if you think it is fun to do and your time is valued at $2/hr*. Otherwise, look for a PCB house. MA > My questions: > > 1. What kind of paper works best for this? Glossy paper? What brand? > Specially designed paper? What are your experiences? I used gel coated paper ; the surface dissolved in water. The stuff I used is no longer sold. Someone sells "security paper" which dissolves in water. Hot water dissolves stuff faster than cold water. > > 2. What printer should be used? Laser or inkjet? What are your > experiences? Laser worked for me. Laser printers vary radically in quality. > > > 3. When printing designs for fine pitch TQFP components such as the > 100 pin PIC32 chip which has a pin pitch of 0.4 mm, where does the > problem lie - during the ink transfer stage or during the actual > etching stage? Both phases > How can this be done more reliably so that no traces > are broken and everything works out well? Cold solution etches slower than hot solution. Thin traces can disappear from being etched away from the side of the trace. > > > 4. When making double sided PCBs, does the same technique apply (other > than pressing the glossy paper on both sides on a double sided blank > PCB)? Use alignment holes > > > 5.
