KIT BUILDING TIPS:

Use a good soldering technique - let your soldering iron tip gently heat the

traces to which you are soldering, heating both wires and pads

simultaneously. Apply the solder on the iron and the pad when the pad is

hot enough to melt the solder. The finished joint should look like a drop of

water on paper, somewhat soaked in.

Mount all electrical parts on the top side of the board provided. This is the

side that has no traces or pads on it.

Electrical part installation - when parts are installed, the part is placed flat to

the board, and the leads are bent on the backside of the board to prevent

the part from falling out before soldering. The part is then soldered securely

to the board, and the remaining lead length is then clipped off.

P-IBM MODEM KIT PARTS INSTALLATION:

We have a twofold "strategy" for the order of the following kit assembly

steps. First, we install parts in physical relationship to each other, so there's

a minimum chance of inserting wires into the wrong holes. Second,

whenever possible, we install in an order that fits our "Learn as you Build"

Kit building philosophy.

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, which means: PLEASE follow the PC board drawing

and the written directions for ALL parts where 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 ICs and so forth.)

4. Don't be afraid of ANY pen-style soldering iron producing enough heat to

damage a part.

5. Trim or "nip" excess wire lengths after soldering.

Now, with that out of the way, let's get building!
