How difficult is it to design and fabricate printed circuit boards?
When you look at a finished printed circuit board—with an often-complex
circuit pattern and a mixture of through-hole and surface mount components—
you may think creating your own boards would be a difficult, time-consuming
task that would require specialized tools and expertise. However, fabricating
your own printed circuit boards can be broken down into the following relatively
simple steps:
1. Generation of the schematic.
2. Placement and routing of the circuit board.
3. Generation of artwork.
4. Exposing and developing the resist layer.
5. Etching the printed circuit board.
6. Tin plating of the printed circuit board.
7. Drilling and shaping, including vias (or barrels).
Depending upon your particular situation, you may not need to complete all
of the steps listed above. The purpose of this book is to explain each of the steps
so you can create your own professional-quality printed circuit boards.
The method of producing printed circuit boards described in this book is
unique. It is a result of years of trial and error and lots of ruined circuit boards!
What makes this process unique is that you don’t need photographic equipment,
lots of strange and dangerous chemicals, or expensive traditional artworks. All
artworks used in this process are printed on plain white paper—no transparencies
or commercially produced photoplots are needed! You can generate these
artworks directly from your own laser printer, ink jet printer, or copier.
