The TDK Group has recently introduced the new ultra-thin ceramic substrate CeraPadTM, which is designed in a multi-layer structure and incorporates ESD protection in it, eliminating the need for separate ESD components. This innovative substrate meets the needs of extreme miniaturization and features the best ESD protection for maximum integrated ESD protection in sensitive applications.
CeraPad ceramic substrates have an ESD protection of 25 kV, while the current state-of-the-art Zener diodes have a standard protection of only 8 kV. CeraPad ceramic substrates offer up to three times better ESD protection than conventional products. In addition, this ceramic substrate is only 300 μm to 400 μm thick, but has a thermal conductivity of up to 22 W/mK, which is more than three times that of conventional carriers. According to customer requirements, CeraPad's contact pads can be designed according to the welding process requirements, and can be applied to standard SAC (Sn / Ag / Cu, 260 ° C) reflow or eutectic (AuSn, 320 ° C) process.
Today, with the ever-increasing number and density of LEDs, this new technology is particularly suitable for a variety of LED applications. CeraPad reduces the standard LED component custom chip package (CSP) from CSP1515 to CSP0707. In addition, CeraPad has a very low coefficient of thermal expansion (6 ppm/mK), which is almost the same as the thermal expansion coefficient of LEDs. Therefore, when the temperature changes, there is almost no mechanical stress between the substrate and the LED.
Similar to PCB boards, the multi-layer technology of CeraPad ceramic substrates can also be designed to integrate certain integrated circuits by re-distributing each layer inside. In general, today's matrix LEDs contain multiple dual LEDs in series. In contrast, the new CeraPad module enables the first implementation of a new type of LED array in which hundreds of LED source points can be independently controlled. Application designers will be able to use this technology to create innovative high-resolution and secure Lighting effects in the smallest spaces, such as multi-LED flashlights on smartphones or adaptive headlights for cars.
With CeraPad ceramic substrates, TDK Group is able to offer its customers an attractive custom packaging solution that allows them to better meet the challenges of rising IC sensitivities in the future, allowing customers to take advantage of a whole new approach. Lighting design and also improved the lighting efficiency of LEDs.
