MOST SOLVENTS WHICH WILL REMOVE ROSIN FLUX
ARE VOLATILE AND TOXIC BY THEIR NATURE AND
SHOULD BE USED ONLY IN SMALL AMOUNTS IN A
WELL VENTILATED AREA, AWAY FROM FLAME SUCH
AS FROM A SOLDERING IRON OR SMOKING MATERI
ALS. OBSERVE THE MANUFACTURER'S CAU
TIONARY INSTRUCTIONS.
5-32. Install the new component and apply solder from the bottom side of the circuit board.
After soldering, remove flux with a cotton swab moistened with a suitable solvent.
Rubbing alcohol is highly diluted and is not effective.
5-33. The board should be checked to ensure the flux has been removed and not just smeared.
Rosin flux is not normally corrosive, but rosin will absorb enough moisture in time to
become conductive and cause problems.
5-34.
INTEGRATED CIRCUITS.
Special care should be exercised with integrated circuits. Each
integrated circuit must be installed by matching the integrated circuit notch with the
notch on the socket. Do not attempt to remove an integrated circuit from a socket with
your fingers. Use an integrated circuit puller to lightly pry the component from the
socket.
