WiSmart™ EC19D0x Datasheet Module Handling Guide Precaution against Electrostatic Discharge When using semiconductor devices, ensure that the environment is protected against static electricity: 1. Wear antistatic clothes and use earth band. 2. All objects that are in direct contact with devices must be made up of materials that do not produce static electricity. 3. Ensure that the equipment and work table are earthed. 4. Use ionizer to remove electron charge. Contamination Do not use semiconductor products in an environment exposed to dust or dirt adhesion. Temperature/Humidity Semiconductor devices are sensitive to: • Environment • Temperature • Humidity High temperature or humidity deteriorates the characteristics of semiconductor devices. Therefore, do not store or use semiconductor devices in such conditions. Mechanical Shock Do not to apply excessive mechanical shock or force on semiconductor devices. Chemical Do not expose semiconductor devices to chemicals because exposure to chemicals leads to reactions that deteriorate the characteristics of the devices. Light Protection In non- Epoxy Molding Compound (EMC) package, do not expose semiconductor IC to bright light. Exposure to bright light causes malfunctioning of the devices. However, a few special products that utilize light or with security functions are exempted from this guide. Radioactive, Cosmic and X-ray Radioactive substances, cosmic ray, or X-ray may influence semiconductor devices. These substances or rays may cause a soft error during a device operation. Therefore, ensure to shield the semiconductor devices under environment that may be exposed to radioactive substances, cosmic ray, or X-ray. EMS (Electromagnetic Susceptibility) Strong electromagnetic wave or magnetic field may affect the characteristic of semiconductor devices during the operation under insufficient PCB circuit design for Electromagnetic Susceptibility (EMS).
