  • WICOP (Wafer Level Integrated Chip on PCB) is a totally new concept for an LED product which has overcome the limits posed by the existing CSP (Chip Scale Package) solutions. Seoul Semiconductor succeeded in developing and producing the product for the first time worldwide in 2012. As it is designed to directly connect the chip to PCB, there is no need for packaging processes, such as die bonding or wire bonding. In addition, as there is no intermediate substrate, the size of the chip and package is 100% the same. It is characterized by the super small size and high efficiency. It is also good for the high luminance and thermal conductivity.

    In the case of the widely available product TOP LED, a variety of equipment is required for the production such as die bonding machines to attach the chip to the lead frame, wire bonding machines to connect electrodes to the gold wire, as well as material in the product itself, such as lead frame, gold wire, and adhesives required in each process. Due to this packaging process a conventional LED results in a package size larger than the actual chip size, and so is space limited as the size of the chip could not be made smaller to meet specification requirements. 

    CSP (Chip Scale Package) technology, derived from silicon, is a technology developed to minimize the size of semiconductor parts (package) to the size of a chip. Generally, when the size of the package does not exceed more than 1.2 times the chip, it is classified as CSP. This technology was applied to the LED industry and other companies announced products using this technology in 2012. However, as products using this technology need die bonding equipment, intermediate substrate or ceramic and silicon material to attach the chip to the PCB, it is difficult to see the technology as a complete CSP. 

    Seoul Semiconductor were the first to introduce a complete concept of WICOP products in which the size of the package (PKG) is the same as that of chip, and does not use other costly materials by directly attaching the chip to the PCB. It started to mass produce relevant products and supply them to client companies, thus firmly establishing its position as the leading company in the industry. Also, it secured global patents in respect to WICOP and succeeded in constructing a technological entry barrier. 

    Since 2013, WICOP has been supplied to main customers for use in LCD backlights and camera flashes, as well as in head lamps of vehicles. With the release of an LED package WICOP for use for lighting applications, Seoul Semiconductor has been able to possess a WICOP product portfolio applicable to all fields of the LED industry. Seoul Semiconductor plans to actively target an LED lighting-source market made up of luminaires, vehicle, and IT products that is  currently estimated to be approximately 20 trillion ($20B) with this WICOP technology. 
     

  • Nano and Micro driver

  • Seoul Semiconductor, a leading global innovator of LED products and technology, has developed the industry’s smallest phase-cut DC LED driver series, with a power density 10x higher than conventional LED drivers. The NanoDriver Series is the world’s smallest miniature converter at just 13.5 mm wide, and is available in four versions rated for 16 W and 24 W output power for operating LED lighting with input power of 120 V or 230 V (50-60 Hz). Manufactured with Seoul Semiconductor’s original Acrich technology, the NanoDriver Series features an IC directly attached to the substrate, dramatically reducing the size of the converter.

    “The new NanoDriver Series will be a game-changer for lighting designers by enabling them to reduce the size, weight and volume of their light fixtures,” explained Keith Hopwood, executive vice-president at Seoul Semiconductor. “This breakthrough in size reduction for the NanoDriver Series is the result of the company’s continuing investment in high voltage LED technology, combined with a unique power topology that results in smaller size, increased efficiency and lower costs.”

    In the future, Seoul Semiconductor will also launch the MicroDriver Series high performance drivers for LED lighting fixtures from 900 to 2400 lumens. The MicroDriver Series is designed with a miniature package that reduces the size of the converter by more than 10X to enable the integration of the control circuitry with the external driver, making it possible to mount more light sources on the board, or reduce the size of the board.

    The NanoDriver Series requires few external components, and delivers 16W or 24W of output power in a package just 13.5mm x 13.5mm x 1.42mm. These drivers are ideal for downlight, flush mount, track and spotlight fixtures. Their small size enables ultra-thin and novel fixture designs in wall sconces, making conventional lamp replacement possible without the need for a large volume recess for the driver, or a reduction in the light output.

    The resulting decrease in the LED drivers’ physical size has significant business implications for the lighting industry, giving lighting designers the ability to shrink the size of light fixtures by as much as 20%, which reduces shipping and storage costs. Because conventional LED drivers are both heavy and bulky, they are typically shipped via sea freight from manufacturers in Asia to European and North American fixture companies, with transit times up to six weeks. The NanoDriver Series are small and lightweight enough to make airfreight practical and economical, reducing transit time and making the overall supply chain more flexible and responsive.

    The NanoDriver Series is available in four models rated for output power of 16W and 24W, for LED assemblies operating at input voltages of 120V or 230V (50 – 60Hz). The drivers have typical efficiencies of 85% and power factor correction (PFC) of <0.9, and are rated for inrush current of <300mA, with an over-temperature protection feature that limits the LED current at temperatures above 160°C. Operating temperature range is -40° to +70°C (ambient) and -20° to +85°C (at TC point).

    The drivers are UL recognized, provide flicker-free, low ripple current operation for phase-cut dimmers, and are compliant to California Title 24, enabling lighting designers to meet the most challenging design requirements, including low flicker, high power factor, Class B EMI and 2kV surge.
