    Abstract: Easily removable conformable coatings having a controlled thickness with a predetermined minimum value are obtained by the application of a composition comprising a mixture of a viscous carrier material and small particles of a second material by any known method. When both the carrier material and the particulate material mixed therewith are selected to have high dielectric constants, the mixture may be used to obtain coatings suitable for protection of circuit boards supporting high impedance electrical circuits. A mixture of a commercially available grease, e.g., Amoco RYKON (TM), with glass microspheres comprising up to 50% of the volume and preferably in the size range 3-5 mils, provides excellent dielectric conformal coatings for high impedance circuit boards. By contrast, by selecting both the viscous carrier material and the particulate matter mixed therein to have high conductivity, electrically conductive coatings for particularized users may likewise be obtained according to this invention.

    Abstract: PROBLEM TO BE SOLVED: To prevent movement and scattering of solder, which occur due to melting of the solder in an electronic component built-in module, by heating when the electronic component built-in module is mounted. SOLUTION: The electronic component built-in module 1 includes the electronic component 2, a substrate 3 on which the electronic component 2 is mounted, a first resin 10 covering the electronic component 2 and the substrate 3 and a second resin 4 covering a surface of the first resin 10. The first resin 10 is constituted of resin having a gap. The first resin 10 is constituted in such a way that an area on which the electronic component 2 is not mounted becomes thicker than an area on which the electronic component 2 is mounted on a surface of the substrate 3. Porosity of the second resin 4 is lower than that of the first resin 10. COPYRIGHT: (C)2011,JPO&INPIT
