APT: High Power Blue LED Multi-Chip Module APT-N4004 Series
The author was unable to visit the APT booth. The information given to me by the reporter was only the picture of this "APT-N4004 series" and a parameter introduction of "High Power Blue LED Multi-Chip Module".
The APT-N4004 Blu-ray series has a wavelength range of 445-465nm and uses multi-chip module (3×3) integration technology; the luminous flux after white light packaging is above 360lm, with high stability and high reliability; Back gold, support eutectic packaging process. The forward voltage is 8.4-9.6V, the forward current IF is 1.4A, and the junction temperature is 125°C. Good ESD protection (≥4000V). Applications include indoor and outdoor, commercial, urban, decorative, architectural and specialty lighting applications.
As early as February of this year, APT developed a high-power module chip (4×1W chip flip-chip) with unique flip-chip soldering technology. The chip size is only 3.36x3.36mm2. The module chip is tested at a voltage of 6.6V and a current of 700mA. The luminous flux of the white light package reaches 422.4lm, and the luminous efficiency reaches 91.4lm/W. Jinko Electronics has started mass production of this high-brightness module chip and promoted it to the market. I don't know if the two are related.
The module chip developed by Jingke Electronics adopts flip-chip bonding technology. Compared with LEDs with formal structure or vertical structure, it realizes gold-free wire interconnection, which has the advantages of high yield of package, excellent reliability and strong heat dissipation capability. It is ideal for ultra-high power chip light sources.
In order to meet the huge demand for the company's products and expand the scale of production, in 2006, APT Electronics Co., Ltd. was established in Nansha District of Guangzhou to establish a number of fully automatic LED production lines. Currently, it has a monthly production capacity of 3KK. Power chip capacity.
