ESD protection for GaP and AlGaAs based chips is still necessary even though they are safe in low static-electric discharge. Parts built with AlInGaP, GaN, or/and InGaN based chips are STATIC SENSITIVE devices. ESD protection has to considered and taken in the initial design stage. If manual work/process is needed, please ensure the device is well protected from ESD during all the process.

The scope of the IEC standard status that “…products which are sold to other manufacturers for use as components of any system for subsequent sale are not subject to IEC 60825-1, since the final product will itself be subject to this standard. ＂ Therefore, it is important to determine the Laser Safety Class of the final product. However, it is important that employees working with LEDs are trained to use them safely. Most of the products containing LEDs will fall in either Class 1 or Class 2. A Class 1 label is optional: WEITRON http://www.weitron.com.tw 7/10 15-Jul-2011 WT-P178NGU CLASS 1 LED PRODUCT If a label is not used, this description must be included in the information for the user. Amendment 2 to IEC 60825-1 is expected to be published in January 2001. The CENELEC equivalent is expected to follow three months after the IEC publication. This document contains increased Class 1 and Class 2 limits, as well as the introduction of less restrictive Class 1M and Class 2M. For the exact classification and further information, the IEC document can be used: EC-60825-1 ISBN 2-8318-4169-0 Tube and Packing Tube Dimension WEITRON http://www.weitron.com.tw 8/10 15-Jul-2011 WT-P178NGU Packing Model Precaution of Application Designing 1: Soldering Pattern The dimensions of the recommended soldering pattern may not meet every user.
