Application Notes For LED Displays Through Hole Display Mounting Method Lead Forming Do not bend the component leads by hand without proper tools. The leads should be bent by clinching the upper part of the lead firmly such that the bending force is not exerted on the plastic body. Not Recommended Recommended Installation 1.The installation process should not apply stress to the lead terminals. 2.When inserting for assembly, ensure the terminal pitch matches the substrate boards hole pitch to prevent spreading or pinching the lead terminals. Not Recommended Recommended 3.The component shall be placed at least 5mm from edge of PCB to avoid damage caused excessive heat during wave soldering Not Recommended Recommended 4 .When performing automated mounting, board bending, and lead-trimming or clinching operations, the stress may damage the resin body. In particular, caution should be taken when clinching or cutting the leads, since the amount of force applied during this time is significant. Therefore, test samples should be run through the lead-forming process then pass through soldering to be check for possible damage before mass production begins.

For products with 90-degree lead bends, Kingbright recommends at least 10mm of clearance between the display and the edge of the PCB during soldering and assembly. Display Soldering Conditions The recommended conditions for soldering are as follows. Because the component is made with epoxy resin, the units are susceptible to heat. Therefore, the preheating and soldering temperatures should be kept as low as possible to avoid damage. 1 . Manual Soldering Conditions (with 1.5mm Iron tip ) Iron Tip Temperature: 350C Max, Time: 3s Max Position: The iron should be situated at least 2mm away from the root of the leads. 2 .
