LCP materials for power LED packages
Vectra LCP liquid crystal polymer materials from Ticona are used by Spectrum Plastics to create open-cavity packages for power LEDs. The use of lead-frame molding principles for LED packages can enable a high-volume, automated process that minimizes part handling and enhances quality With the correct choice of materials, it is now possible to mass-produce packages for power LEDs in fine detail with great precision using this technique.

The popularity introduction of lead-free soldering means that injection-molded LED packages for high-brightness lighting applications must withstand temperatures above 260°C. Of course, thermal issues are paramount when the device is operating, and the package itself must tolerate the effects Of high drive currents, encapsulation and high ambient temperatures (for example, direct sunlight for outdoor lighting applications).
Ticona Engineering Polymers, the Florence, Kentucky-based subsidiary of Celanese Corporation, has developed liquid crystal polymer (LCP) materials that are suited to the demands of power LED devices.
