Bio-Electronic Device Engineering Utilizing Liquid Crystal Polymers
Liquid Crystal Polymer (LCP), a thermoplastic dielectric material with very low water absorption (< 0.04%), high chemical stability and low thermal expansion is best suited both as a substrate material and as the encapsulate for small miniaturized electronic packages and modules. LCP stands out among other polymer materials used for microelectronics. The permeability for water and gases is the lowest among all polymeric materials. With proper design considerations LCP packages can achieve a sufficient hermeticity for exposures in aggressive or bio-sensitive environments. Processing techniques for LCP substrates are the same as for other packaging substrate materials. Resolution of lines, spacing and vias are comparable. LCP is a homogenous material and can be easily machined with UV lasers with a precision down to the micrometer scale. Cavities, openings for recessed components can be integrated. Silicon sensors dies, such as MEMS pressure sensors, laser-diodes or photo-diodes can be embedded in such a way that the sensor surface is open to the outside of the substrate.
Dr. Eckardt Bihler graduated with a PhD in solid state physics from the University of Stuttgart in 1990 with a thesis on piezoelectricity in polymers. In his almost 30 year career in the microelectronics industry he collected considerable experience in ceramic and organic microelectronic packaging, semiconductor design, photovoltaic and printed circuit board processing technologies. He worked for IBM, Weidmueller, AT&S and as an independent technical and business consultant. Since eight years he works for Dyconex AG, a speciality flex PCB manufacturer in Switzerland, as a business development manager. His special interests are with Liquid Crystal Polymer (LCP) and its use for miniaturized medical electronic devices. He is an inventor of several patents in the field of miniaturized electrodes, catheters and electronic medical devices.
