DEM 240320E TMH-PW-N(A-TOUCH) Production Specification 11. PRECAUTIONS IN USING 11.1 Liquid crystal display (LCD) The LCD panel is made up of glass, organic fluid and polarizer. When handling, please pay attention to the following items: 1) Keep the operation and storage temperature of the LCD within the range specified in the LCD specification. Otherwise, excessive temperature and humidity would cause polarization degradation, bubble generation or polarizer peel-off.
DEM 240320E TMH-PW-N(A-TOUCH) Production Specification 11.4 Precaution for soldering 1) Soldering should apply to I/O terminals only. 2) Soldering temperature is 280℃+(-)10℃. 3) Soldering time 3-4 seconds. 4) Eutectic solder (rosin flux filled) should be used. 5) If soldering flux is used, be sure to remove any remaining flux after finishing the soldering operation and LCD surface should be covered during soldering to prevent any damage to flux spatters.
