Allow approximately 1/4" of wire to extend beyond the end of the soldering iron. Cut the wire end to a chisel shape as shown. After the iron is hot, apply solder to the wire windings. Due to the small foil area around circuit board holes at integrated circuits, and the small areas between foils, it will be necessary to use the utmost care to prevent solder Resistors will be called out by their resistance value in §2, kS2, or M2, and color code. bridges between these adjacent foil areas. Use only a minimum amount of solder, and do not heat components excessively with the soldering iron. Diodes, transistors, etc., Capacitors will be called out by their capacitance value (in pF or uF) and type (disc, can be damaged if subjected to excessive amounts of heat. Apply the soldering iron Mylar, or electrolytic). only long enough to make a good solder connection. NOTE: For soldering integrated circuits you need a small wattage, small-tip soldering SAFETY WARNING: Avoid eye injury when you clip off excess leads. We suggest that iron. If one of these is not available, proceed as follows: Be sure your soldering iron is you wear glasses, or at least clip the leads so the ends will not fly toward your eyes.
