Abstract:
An interleaving striped capacitor substrate structure for pressing-type print circuit boards is disclosed. To meet the high-frequency, high-speed, and high-density requirements in modern electronic systems, the interleaving striped capacitor substrate structure uses several dielectric materials of different dielectric coefficients to make a dielectric layer. One dielectric layer can be stacked on another to form a multi-layered capacitor substrate so that a single capacitor substrate can provide the highest capacitance required for the decoupling capacitor to suppress high-frequency noise signals, and the lower dielectric coefficient substrate required for high-speed signal transmission. This simultaneously achieves the effects of reducing high-frequency transmission time and suppressing high-frequency noise.
Abstract:
The present invention relates to ink jet recording materials and method for making the same. The material has a gel layer formed on a base material to improve the optical density of the material and improve the printing quality of ink of pigment type. The method for forming the gel layer is to coat a first ink-receptive layer composed of high valance metallic halide, such as calcium chloride (CaCl2) or magnesium chloride (MgCl2), on the base layer, then a second ink-receptive layer composed of alginate, such as sodium alginate, potassium alginate or other compounds of alginic acid, on the first ink-receptive layer. The second and the first ink-receptive layers will react to form a gel layer during coating for absorbing ink dots and improving print quality.
