10 ELECRAFT
Tools
You will need the following tools to build this kit:
• Fine-tip temperature-controlled ESD-safe soldering station
with 700 to 800°F tip (370-430°C). Recommend a spade tip
approx. 0.05” (1.3 mm) wide. Do not use a high-wattage iron
or soldering gun since this can damage pads, traces, or the
parts themselves.
• IC-grade, small-diameter (.031”) solder (Kester #44 or
equivalent).
i
DO NOT use acid-core solder, water-soluble flux solder,
additional flux or solvents of any kind. Use of any of these will
void your warranty.
• Desoldering tools and supplies are invaluable if you make any
modifications or need to do any repairs. Narrow solder wick or
a good vacuum desoldering tool such as the Soldapullt®
model DS017LS are recommended. See Soldering and
Desoldering, on page 11 for more information.
• Screwdrivers: A small #2 Phillips, a small flat-blade for
slotted screws and a very small flat-blade (about 0.1 in or 2.5
mm wide) with an insulated handle to adjust the trimmer caps.
• Needle-nose pliers.
• Small-point diagonal cutters. Flush-cutting type is required
(Xcelite MS54-5J or equivalent).
• Digital Multimeter (DMM) for voltage checks and confirming
resistor values. A DMM with capacitance measurement
capability is desirable, but not required.
• 50-ohm dummy load capable of handling 5 watts, minimum.
• Magnifying glass or visor.
We strongly recommend that you use a conductive wrist strap and
anti-static mat during assembly. These items are available at very low
cost from Jameco, Mouser, and other electronics suppliers.
