RECOMMENDED SOLDERING CONDITIONS This product should be soldered under the following recommended conditions. For soldering methods and conditions other than those recommended below, contact your NEC sales representative. Recommended Condition Symbol IR30-00-3 Soldering Method Infrared Reflow Soldering Conditions Package peak temperature: 230 C or below Time: 30 seconds or less (at 210 C) Note Count: 3, Exposure limit: None Package peak temperature: 215 C or below Time: 40 seconds or less (at 200 C) Note Count: 2, Exposure limit: None Soldering bath temperature: 260 C or below Time: 10 seconds or less Note Count: 1, Exposure limit: None Pin temperature: 300 C Time: 3 seconds or less (per side of device) Note Exposure limit: None VPS VP15-00-2 Wave Soldering WS60-00-1 Partial Heating - Note After opening the dry pack, keep it in a place below 25 C and 65 % RH for the allowable storage period. Caution Do not use different soldering methods together (except for partial heating). For details of recommended soldering conditions for surface mounting, refer to information document SEMICONDUCTOR DEVICE MOUNTING TECHNOLOGY MANUAL (C10535E). Preliminary Data Sheet P14544EJ1V0DS00 11 NE52118 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 law concerned and so on, especially in case of removal. * The information in this document is subject to change without notice. Before using this document, please confirm that this is the latest version. * No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation. 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. * Descriptions of circuits, software, and other related information in this document are provided for illustrative purposes in semiconductor product operation and application examples. The incorporation of these circuits, software, and information in the design of the customer's equipment shall be done under the full responsibility of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third parties arising from the use of these circuits, software, and information. * 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, customers 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: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "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 an NEC sales representative in advance. M7 98. 8 |
