"LEARN-AS-YOU-BUILD" ASSEMBLY STRATEGY:
To help you learn just what exactly is going on we'll discuss the purpose
of most of the components or groups of components as we go along.
Since we are trying to keep assembly of the board simple, we will not be
able to fully describe each individual component’s function as you build,
but Ramsey's "Learn-As-You-Build" kit assembly philosophy still
stands.
Check off each step as understood and completed. Examine the
schematic diagram and PC-board X-ray illustration as you proceed. In
all steps, “install” means to insert into the correct PC-board holes, solder
properly, and trim all excess component leads.
Use good soldering skills - let your soldering iron heat each connection
wire so that the wire itself and the foil trace both become hot enough
together to melt the applied solder so that it flows smoothly around the
wire lead and on to the PC board trace.
Mount all electrical parts on the top side of the board provided. This is
the side that has no traces or pads on it. When parts are installed, they
are placed flat on the board, and the leads are bent on the backside of
the board to prevent the part from falling out before soldering. The part
is then soldered securely to the board, and the remaining lead length is
then clipped off. The clipped off leads should be saved for later use as
jumper wires.
As you can see in examining the circuit board and parts there are many
tall components such as the potentiometer, capacitors, and switches
along with a lot of small parts. First you will install the larger components
so they can be used as markers. So that you don't spend extra time
"troubleshooting" we strongly recommend that you follow the assembly
strategy and step-by-step procedures we have provided.
