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 wires and
pads simultaneously. Apply the solder on 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.
This is the side that has little or no traces on it. 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 on close up, clean and smooth
with no holes or sharp points (6).
