Step 3. Solder the Resistors When all the resistors are soldered into place,
your board will look like Figure 9-7.
We can now solder all the resistors in place. Take
special care with R5, which is soldered at an angle
Step 4. Solder the IC
across one of the links. The leads of the resistor
should be kept away from the wire of the link. Place the IC in position (see Figure 9-8), ensuring
However, it does not matter if the body of the that it is the right way around—the little dot
resistor touches the link. indicating pin 1 should be on the top left. Solder
