SURFACE MOUNTED INTEGRATED CIRCUIT REPLACEMENT
• CAUTION: Some chemicals may damage the internal and external plastic parts of the radio.
Soldering and de-soldering techniques of the surface mounted IC’s are similar to the above outlined procedures for
the surface mounted chip components. Use extreme care and observe static precautions when removing or replacing
the defective (or suspect) IC’s. this will prevent any damage to the printed circuit board or the surrounding circuitry.
The hot-air soldering system is the best method of replacing surface mount IC’s can easily be removed and installed
using the hot-air system. See the manufacturers instructions for complete details on tip selection and other operating
instructions unique to your system.
If a hot-air system is not available, the service technician may wish to clip the pins near the body of the defective IC
and remove it. the pins can then be removed from the PCB with a standard soldering iron and tweezers, and the new
IC installed following the Surface Mount Component Replacement procedures. It may not be necessary to "tin" all
(or any) of the IC pins before the installation process.
