SERVICING PRECAUTIONS Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components are commonly called Electrostatically Sensitive (ES) Devices. The typical examples of ES devices are integrated circuits, some field-effect transistors, and semiconductor “chip”...
SERVICING PRECAUTIONS FIGURE 1. USE SOLDERING IRON TO PRY LEADS IC Removal/Replacement Some utilized chassis circuit boards have slotted (oblong) holes through which the IC leads are inserted and then bent flat against the circuit foil. When holes are slotted, the following technique should be used to remove and replace the IC.

SERVICING PRECAUTIONS Diode Removal/Replacement 1. Remove defective diode by clipping its leads as close as possible to diode body. 2. Bend the two remaining leads perpendicularly to the circuit board. 3. Observing diode polarity, wrap each lead out of the new diode around the corresponding lead on the circuit board.
