Finally, here are a few words about diodes (Figure 3-20). The marking on small
signal diodes usually is a band or stripe that denotes the cathode. These diodes are
inserted into a perforated (perf) board by bending the leads to at least 114 inch of
lead length from each side of the body of the diode to avoid stress that otherwise
would crack the glass casing. See the example in Figure 3-21.
