circuit board that has been printed onto transparency film using an
ink-jet printer.
After successfully transferring the artwork to a transparency, the
following instructions can be used to create a board. A 4- 6-inch
presensitized positive copper board is ideal for all of the projects
presented in this book. When you place the transparency on the
copper board, it should be oriented exactly as shown in each
chapter. Make any sensor boards that go with the particular proj-
ect at the same time. A company that specializes in providing pre-
sensitized copper boards and all the chemistry needed to fabricate
boards is M.G. Chemicals. Information on how to obtain all of the
supplies can be found on its Web site: www.mgchemicals.com.
Figure 2.2 shows the developer, ferric chloride, and presensitized
copper board that will be used for fabricating the circuit boards.
