RAMSEY Learn-As-You-Build KIT ASSEMBLY
There are many solder connections on the TS4 printed circuit board. There-
fore, PLEASE take us seriously when we say that good soldering is essential
to the proper operation of your transmitter!
• Use a 25-watt soldering pencil with a clean, sharp tip.
• Use only rosin-core solder intended for electronics use.
• Use bright lighting; a magnifying lamp or bench-style magnifier may
be helpful.
• Do your work in stages, taking breaks to check your work. Carefully
brush away wire cuttings so they don't lodge between solder connec-
tions.
We have a two-fold "strategy" for the order of the following kit assembly steps.
First, we install parts in physical relationship to each other, so there's minimal
chance of inserting wires into wrong holes. Second, whenever possible we in-
stall in an order that fits our "Learn-As-You Build" Kit building philosophy. This
entails describing the circuit that you are building instead of just blindly install-
ing components. We hope that this will not only make assembly of our kits
easier but help you to understand the circuit you’re constructing.
For each part, our word "Install" always means these steps:
1. Pick the correct part value to start with.
2. Insert it into the correct PC board location.
3. Orient it correctly, follow the PC board drawing and the written
directions for all parts - especially when there's a right way
and a wrong way to solder it in. (Diode bands, electrolytic capacitor
polarity, transistor shapes, dotted or notched ends of IC's, and so
forth.)
4. Solder all connections unless directed otherwise. Use enough heat
and solder flow for clean, shiny, completed connections.
SINGLE SIDED COMPONENT SOLDERING INSTRUCTIONS:
You’ll notice that the circuit board contains plating on only one side of the
board. This makes soldering relatively easy for even the inexperienced kit
builder. Just take your time and be sure to apply enough heat to the connec-
tions. Don’t be too afraid of overheating a component; most are fairly hardy
and a weak connection will prevent your kit from working properly.
