CHIP HANDLING
DIE ATTACHMENT Die attach operation can be accomplished with Au-Sn (within a 300 C - 10 s) performs in a forming gas environment. Epoxy die attach is not recommend. BONDING Bonding wires should be minimum length, semi hard gold wire (3-8 % elongation) 20 microns in diameter. Bonding should be performed with a wedge tip that has a taper of approximately 15 %. Bonding time should be kept to minimum. As a general rule, the bonding operation should be kept within a 280 C, 2 minutes for all bonding wires. If longer periods are required, the temperature should be lowered. PRECAUTIONS The user must operate in a clean, dry environment. The chip channel is glassivated for mechanical protection only and does not preclude the necessity of a clean environment. The bonding equipment should be periodically checked for sources of surge voltage and should be properly grounded at all times. In fact, all test and handling equipment should be grounded to minimize the possibilities of static discharge. Avoid high static voltage and electric fields, because this device is Hetero Junction field effect transistor with shottky barrier gate.
CAUTION
The Great Care must be taken in dealing with the devices in this guide. The reason is that the material of the devices is GaAs (Gallium Arsenide), which is designated as harmful substance according to the law concerned. Keep the Japanese law concerned and so on, especially in case of removal.

NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices in "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact NEC Sales Representative in advance. Anti-radioactive design is not implemented in this product.
