POPULATING THE PRINTED CIRCUIT BOARD
Your work space should be well-lit, well-ventilated, and disposable; that is, don’t work on the nice dining
room table! Work on a utility surface that you can burn, drill and scratch. A piece of ¼” tempered
masonite, or a chunk of MDF, makes an excellent surface if you don’t have a utility work bench.
CAUTION
: Solder fumes are not healthy for you. The fumes consist of vaporized flux, which can
irritate your nose, lungs, and even your skin. You MUST work in a space where the air drifts away from
you as you work, so fumes do not rise straight into your face.
CAUTION
: Solder residue usually contains lead, which is poisonous if you ingest it. Do not breathe
the fumes, do not eat the supplies, wash your hands after you handle solder, and sweep and wipe up
your work space after EVERY USE.
