Annwa high surface mount RGB LED products for outdoor display panel applications

Avago Technologies (Annwa Technology) announced the day before, the launch of a new series of high brightness surface mount three color light emitting diode (LED) products, will be able to help the designers to develop more and more sharp vivid images and graphic output of large indoor and outdoor electronic display device, this new series of high brightness RGB LED standard PLCC-4 package delivery in particular, for the outdoor environment design and operation of more stringent.

Avago's new ASMT-QTB2 series high brightness AllnGaP and InGaN three color LED by strengthening production type silicone resin material, besides having high reliability and long service life, can dramatically reduce color deterioration, long time use in addition, ASMT-QTB2 series also provides a 120 degree ultra wide viewing angle, can improve the visibility of bright sunlight large display outdoor billboards, the typical application of Avago high brightness ASMT-QTB2 LED including RGB stadium scoreboard, bulletin board, lantern and electronic variable message signs etc..

In addition to high brightness, long and compact size, ASMT-QTB2 Avago surface mount LED production environment brings two advantages, first of all, they can adopt the traditional surface mount technology simple welding, greatly reduce the production cost, in addition the package also after JEDEC moisture sensitivity level 2A certification, for manufacturers, representatives of this level these LED can leave the sealed package placed at room temperature (30 C and 60% relative humidity) reached around without moisture absorption in the removal of pre production.

InGaN and AllnGaP ASMT-QTB2 LED Avago package which provides low thermal resistance, can make the heat from the package in a more efficient heat dissipation to the motherboard, so the device can maintain long-term reliability at the same time, it is more standard and SMT reflow process compatible, and the MSL 2a for the moisture sensitive level can bring to the customers in assembling products with greater flexibility.
