off the board. W it h heat, the surface of the ink jet paper fuses to
the copper. If you have problems getting the paper to free itself
from th e board after iro ning, then a little experimentation will be
in order. You migh t be able to print the artwork with a ph otocopi-
er as long as it wi ll use glos sy paper.

Board Cutting and Cleaning

Afte r printing the artwork, I decide how big a piece of copper
board I need, then cut it on my little table saw using a nonferrous
blade (see Figure 3.6).
Because I have a tendency to purchase material considered sur-
plus, I generally have a li ttl e extra work before I can use it. In this
case the PCB materia l is oxidi zed so I will clean it up with some
superfine steel wool (see Figure 3.7).

After the steel wool treatment, I wa sh the board w ith dish soap
and hot water (as seen in Figure 3.8), making sure t keep my
hand s off of the copper.
If yo u aren't careful w hen han dling the board, your cleani ng will
be to no avail because the oil from yo ur fingers will inhibit the
