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 important 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!
Kit building tips:
Use a good soldering technique - let your soldering iron tip gently heat the
traces to which you are soldering, heating both the wires and pads
simultaneously. Apply the solder to the pad and wire allowing them to melt
the solder not the iron. The finished joint should look like a tepee.
Mount all electrical parts on the top side of the board provided unless other
wise directed. The top side has the silk screen of the parts with their
reference designations. When parts are installed, the part is placed flat to the
board, and the leads are bent on the backside of the board to prevent 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 then clipped off (5).
Notice how the solder joint looks close up, clean and smooth with no holes or
sharp points (6).
