RAMSEY Learn-As-You-Build KIT ASSEMBLY

There are numerous solder connections on the DN1 printed circuit board. Therefore, PLEASE take us seriously when we say that good soldering is essential to the proper operation of your Doctor Nicad!

•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 connections.

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 install 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 installing 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.

Now, let's get building!

Since you may appreciate some “warm-up” soldering practice as well as a chance to put some “landmarks” on the PC board, we’ll first install some “hardware” components. This will also help us to get acquainted with the up - down, left - right orientation of the circuit board. Remember that the components will be mounted on the “component” side of the circuit board and soldered on the “solder” side of the circuit board.
