With the continuous development of LED display technology, the upgrade, development and innovation of packaging technology have been further promoted. Today, the editor will show you the six major packaging technologies in the LED industry.
[CSP chip scale packaging] As the most popular packaging technology for LED devices, CSP chip scale packaging has the advantage of miniaturization and is widely used in display device backlights, mobile phone flashes, etc. In the future development of CSP packaging, it will develop towards a trend of high cost performance.
[De-power module packaging] is to place the drive circuit and the lamp beads on the same substrate to achieve a high degree of integration between the two, built-in power sources, and reduce electrolytic capacitors. This packaging technology is more convenient for mass and automated production and reduces production costs. .
[Flip-chip LED technology package] has the advantages of high density and high current, reduces unnecessary links, reduces the probability of dead lights, ensures product stability and optimizes product heat dissipation. It is the best solution for overcurrent driving.
[EMC Package] EMC has the advantages of heat resistance, UV protection, small size, and high stability. It is a thermosetting plastic, especially for outdoor applications. It has outstanding advantages.
[High-voltage LED package] High-voltage LED is the decomposition of large-sized chips into small chips. The small chips have high luminous efficiency and uniform light emission, which can effectively improve the brightness and reduce the voltage difference, thereby reducing the cost of the system. This is the trend of industry development. one.
[COB integrated packaging] COB integration can be understood as a light-emitting body in which multiple LED chips are integrated and packaged on the same substrate. It has the advantages of anti-glare, high brightness, etc., can solve the problem of color difference and heat dissipation, and will move towards large-scale production in the future. The direction of development.
