The synthesizer modules each contain a number of miniature
components to be soldered onto a printed circuit board. Although
the components are heat resistant, a minimum of heat should be.
used to make the required connections. Accordingly, use only a
small, low wattage, "pencil" type soldering iron;a 10 to 30 watt
iron with a 1/32 or 1/16 inch tip is ideal. Use only 60/40 grade
electrical solder with a non-corrosive rosin core flux.If you
are not sure what kind of solder you have, don't take the chance.
Solder is inexpensive, and use of the wrong type, such as acid
core solder,or a paste flux, may severly damage the boards and
components and void the warranty.
TOOLS A small pair of wire cutters, needle-nose pliers, wire
strippers, and small and medium screwdrivers complete the list
of tools you will need. These are standard electronic tools
available at most supply houses.
INSTALLATION OF COMPONENTS The main assembly job consists of
soldering several types of small parts, called components, onto a I
printed circuit board. Parts are carefully packed at our 2, '
factory. However, if you find parts to be missing or damaged,", please '. .;
wrire our customer service office, describing the part carefully ■
so that we can replace it.; All-parts will be installed on the
blank side of the board with their leads extending through to the
foil side. In attaching components to the board use the following
procedure. , . :
1. Bend the leads of the component to align them with the .
holes in the board...
2. Insert the component into the board, double checking to be
sure the part is aligned properly with respect to polarity
ifif required) and to be certain it is correctly located.
3. Using a minimum "of heat * s\d solder, solder the component; to ' \
the foil pads. Be sure the solder does not flow over onto an ;
, ■... adjacent pad, as this could possibly result in damage when
. ^ power is applied to the circuit. — ...--.---.•• -
4. Clip the'excess leads ol£ at-ore" ,rpeak"af the solder joint,
and inspect the joint to be certain that it is "good"
(rounded and shiny,flowing smoothly over the pad and the
lead) and that no solder has run over onto nearby pads or
leads. ,. •••'..'• ."• 'V' ix; - .'• >■"•!'■t\

PARTS ORIENTATION (POLARITY) IMPOSTANT-§ome parts must be
installed in the proper direction, while others, such as'resistors,
do not matter, AN INCORRECTLY INSTALLED PART WILL NOT FUNCTION,
MAY BURN OUT, AND MAY DESTROY OTHER PARTS! Here is a general
outline for proper orientation. Refer to this section during
assembly,,
