An adjustable clip for flexible flat cables comprising a pair of pivotally interconnected scissors arms having retainer tabs on the opposite ends and detents so that angle between the arms can be set in any of several different positions to accommodate FFCs of different widths. 1 to 20 vol % in the silicone rubber layer, and 3) the pigment dispersant contains an organic complex compound including a metal and an organic compound. Of particular relevance for bone implants are coatings which comprise calcium and phosphate. In a preferred embodiment the substantially planar surface is formed by filling gaps between the conductive or semiconductor features with a first dielectric such as oxide, recessing the oxide, filling with a second dielectric such as nitride, then planarizing to coexpose the nitride and the conductive or semiconductor features.
