DEM 24252 SYH-LY General Specification 13 Handling and Precautions for using LCD/LCM LCD/LCM is assembled and adjusted with a high degree of precision. Do not attempt to make any alteration or modification. The followings should be noted. General Precautions: 1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong pressure onto the surface of display area. 2. The polarizer used on the display surface is easily scratched and damaged. Extreme care should be taken when handling.
DEM 24252 SYH-LY General Specification Soldering Precautions: 1. Soldering should be performed only on the I/O terminals. 2. Use soldering irons with proper grounding and no leakage. 3. Soldering temperature: 280°C+10°C 4. Soldering time: 3 to 4 second. 5. Use eutectic solder with resin flux filling. 6. If flux is used, the LCD surface should be protected to avoid spattering flux. 7. Flux residue should be removed. Operation Precautions: 1.
