Soldering is not hard if the proper procedure is followed. The soldering iron is to
be used to heat up the PC pad and component lead, and the solder applied to
the pad, where it melts and flows into the hole. Do not melt the solder onto the
tip of the iron and then attempt to dab it onto the joint – a defective connection
will result! After soldering, check the top (component side) of the board, to be
sure the solder has filed the hole completely, and wicked up around the
component lead. Re-heat and apply more solder if necessary.
The PC boards used for the circuit and for enclosure are contained in two
panels, with the individual boards separated by V-groves. To begin assembling
the kit, the boards must be separated. Placing a panel on a table or workbench
so that the v-groove rests over the edge, the boards may be cleanly separated
by pressing down firmly on each section.
CAPACITORS
The ceramic monolythic capacitors used throughout the kit are small and their
markings not always easy to read. Use a magnifier to verify their values before
installing. Electrolytic capacitors must be installed in the correct polarity. The
cases are marked to indicate the negative terminal, which goes into the round
pad on the board.
Install the capacitors, solder and trim the leads. Check off each part as you
install it.
After C15, the dipped silver mica capacitor is installed, save the leads you
trim off of it. Set them aside – you'll need them later!
