HowTo: How to make printed circuit boards
( Robert Stark)
Step 10 : A pressing issue
|
| | Check your board for cleanliness one last time. Make sure there are no stray pieces of steel wool on the copper. Put your board on a piece of paper (important for later). Place your P-N-P design (image side down) on your board. Make sure your design is lined up the way you want it then carefully place another piece of paper on top of that. This top piece of paper helps keep friction down between the plastic P-n-P and the iron, also, if you have hard water like I do, the iron has a tendency to dribble little pieces of grit out of the steam holes. These will scratch the plastic and ruin your design: the paper prevents this as well.
