RAMSEY “LEARN-AS-YOU-BUILD” ASSEMBLY STRATEGY
Completely read through all of the steps and check the boxes as you go to be
sure you didn't miss any important assembly instructions. Although you may
be in a hurry to see results, before you switch on the power check all wiring
diodes, transistors, IC’s, and capacitors for proper orientation. Also check the
board for any possible solder shorts and/or cold solder joints. Any of these
mistakes could have detrimental effects on your kit - not to mention your ego!
Kit building tips:
!!! IMPORTANT !!!
DUE TO THE EXTREME SENSITIVITY OF THE WCT3, ATTEMPTING TO
CLEAN THE ROSIN FLUX FROM THE BOARD MAY RESULT IN DE-
GRADED PERFORMANCE OF THE UNIT. WE HIGHLY RECOMMEND
THE USE OF ONLY NO-CLEAN ROSIN CORE SOLDER.
Warning: Use only rosin core solder or solder designed to be used with elec-
tronic equipment. Use of acid core solder will void your warranty and produce
a board that will disintegrate in a short period of time.
For Through-Hole Components, the word "Install" means:
1. Pick the correct part type and value or part number.
2
. Mount all electrical components on the top (silkscreened) side of the
PC board unless otherwise noted.
4. Orient the part correctly. Follow the PC board drawing or silk screen
and the written directions for every part! Certain types of parts must be
installed with the proper leads in specific holes. Things to watch for in-
clude diode bands, electrolytic capacitor polarity, transistor shapes, dotted
or notched ends of IC's, and so forth.
5. Insert the part into the correct PC board loca-
tion. Make sure the part is mounted as close to
the PC board as possible, unless otherwise
noted. Most parts, including lay down parts, have
holes or pads that are located inside or near a
rectangle, oval, or circle. Stand up resistors, di-
odes, or inductors have a circle around one pad
(part body location) with a line leading from that
circle to the other pad (lead only).
6. Bend the component and insert thru the
board and then bend leads on the backside of the
board to prevent the part falling out before soldering.
7. Flip board and solder all connections unless di-
rected otherwise. Apply a touch of solder to the iron
tip and then heat both the component lead and
