Precaution for handling of substrate Do not exceed to bend the board after soldering this product extremely. (reference examples) • Mounting place must be as far as possible from the position, which is close to the break line of board, or on the line of large holes of board. • Do not bend extremely the board, in mounting another components. If necessary, use back-up pin (support pin) to prevent from bending extremely. • Do not break the board by hand. break it. We recommend to use the machine or the jig to 8.2. Precaution for soldering Note that this product will be easily damaged by rapid heating, rapid cooling or local heating. Do not give heat shock over 100°C in the process of soldering. We recommend to take preheating and gradual cooling. FWP322512A L Series Engineer Specification  „ All Specifications are subject to change without notice.  Version: A4  Page 7 of 9  8.3.
