MICRO-PHOTOELECTRIC (DISPLAY) PACKAGING

Mini/Micro LED generally refers to LED display technology with a chip size within 200/50um and a pixel pitch less than 1.0mm. With the continuous maturity of LED production and packaging technology, mini/micro LED display technology is developing rapidly. Mini/Micro LED display technology can be used in TV, PC, tablet, mobile phone, wearable, etc. As the application of advanced packaging technologies such as flip-chip continues to evolve, the packaging density of mini/micro LED significantly increases, while the pixel pitch is getting smaller and smaller. The complex packaging process poses a new challenge to solder. Fitech provides reliable solder and solution support for the mini/micro LED micro-photoelectric display industry.
