Surface mounted integrated circuit replacement

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. The IC’s can -easily be removed and installed using the hot-air system. See the manufacturer’s instructions for complete details on tip selection and other operating instructions unique to your system.

If a hot-air systems 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 iron and tweezers, and the new IC installed following the Surface Mount Component Replacement procedures.

Provided that the IC is relatively new, It will not be necessary to ‘tin’, all (or any) of the IC pins before the installation process.

If the IC has been in stock for some time, cleaning, and tinning of the pins may be necessary.
