Static Electricity
Because semiconductor devices are particularly susceptible to damage by static electricity, you must take the following
precautions:
1. Maintain relative humidity in the working environment between 40% and 70%.
You may need to use an apparatus for ion generation to remove electricity.
2. Electrically ground all conveyors, solder vessels, soldering irons, and peripheral equipment.
3. Eliminate static body electricity by using rings or bracelets connected to the ground through high resistance (on the level of
1
MΩ). Wearing conductive clothing and shoes, use of conductive floor mats, and other measures to minimize shock loads is
recommended.
4. Ground all fixtures and instruments, or protect with anti-static measures.
5. Avoid the use of styrofoam or other highly static-prone materials for storage of completed board assemblies.

Precautions for Use Environment
Reliability of semiconductor devices depends on ambient temperature and other conditions as described above.
For reliable performance, do the following:
1. Humidity
Prolonged use in high humidity can lead to leakage in devices as well as printed circuit boards. If high humidity levels are
anticipated, consider anti-humidity processing.
2. Discharge of Static Electricity
When high-voltage charges exist close to semiconductor devices, discharges can cause abnormal operation. In such cases,
use anti-static measures or processing to prevent discharges.
3. Corrosive Gases, Dust, or Oil
Exposure to corrosive gases or contact with dust or oil may lead to chemical reactions that will adversely affect the device. If
you use devices in such conditions, consider ways to prevent such exposure or to protect the devices.
4. Radiation, Including Cosmic Radiation
Most devices are not designed for environments involving exposure to radiation or cosmic radiation. Users should provide
shielding as appropriate.
5. Smoke, Flame
CAUTION: Plastic molded devices are flammable, and therefore should not be used near combustible substances. If devices
begin to smoke or burn, there is danger of the release of toxic gases.
Customers considering the use of Cypress products in other special environmental conditions should consult with sales
representatives.
