RAMSEY "LEARN-AS-YOU-BUILD" ASSEMBLY STRATEGY
Be sure to read through all of the steps, and check the boxes as you go to be
sure you didn't miss any steps. Although you may be in a hurry to see results,
before you switch on the power check all wiring and capacitors for proper
orientation. Also check the board for any possible solder shorts and/or cold
solder joints. All of these mistakes could have detrimental effects on your kit -
not to mention your ego!
Through-hole part installation:
Use a good soldering technique - let your soldering iron tip gently heat the
traces to which you are soldering, heating both wires and pads simultaneously.
Apply the solder to the iron and the pad when the pad is hot enough to melt the
solder. The finished joint should look like a drop of water on paper, somewhat
soaked in.
Mount all electrical parts on the top side of the board provided. The top side is
clearly marked with the word "TOP"; you can't miss it. When parts are installed
each part is placed flat to the board and the leads are bent on the backside of
the board to keep the part from falling out before soldering (1). The part is then
soldered securely to the board (2-4), and the remaining lead length is clipped
off (5). Notice how the solder joint looks on close up, clean and smooth with no
holes or sharp points (6).
Since this is a "professional" piece of test equipment, we sincerely hope you
put this together in a professional manner. Follow good assembly techniques,
and follow all instructions. No matter how clear we may think our manual is, if
you have any questions give us a call at the factory instead of jumping to
conclusions, we will be happy to help you with any problems.
This is a mixed signal project meaning there is digital and RF circuitry all in
one unit. As with all RF circuitry, we want to mount the parts AS LOW AS
POSSIBLE to the board. A 1/4" lead length on a resistor not mounted close to
