3M Introduces Thinner Embedded Capacitance Material for High-Performance Circuit Boards.AUSTIN, Texas -- 3M announced today that it has developed an improved embedded capacitance material that has a dielectric thickness of 8 microns and a capacitance density over 11 nanofarads per square inch, which makes it among the thinnest and highest capacitance density materials available for embedding planar A technique developed by Fairchild Instruments that creates transistor sublayers by forcing chemicals under pressure into exposed areas. Planar superseded the mesa process and was a major step toward creating the chip. capacitance in circuit boards. Fabricators and OEMs worldwide can use this material without a license from 3M. 3M will be exhibiting at the IPC (1) (InterProcess Communication) The exchange of data between one program and another either within the same computer or over a network. It implies a protocol that guarantees a response to a request. Printed Circuits Expo, Feb. 22-24, 2005, at the Anaheim Convention Center Anaheim Convention Center is a major convention center in Anaheim, California. It is located across from the Disneyland Resort on Katella Avenue. Much of the Anaheim Convention Center has been renovated in recent years with state-of-the-art facilities. in Anaheim, Calif., in Booth 1549. "Using embedded capacitance for decoupling Decoupling The occurrence of returns on asset classes diverging from their normal pattern of correlation. Notes: Take for example stock and corporate bond returns, which normally rise and fall together. high-speed electronics offers many benefits, such as improved noise margins, faster signaling, less-radiated emissions and reduced capacitor counts," said Bill Balliette, new business development manager, 3M Electronic Solutions Division. "This thinner laminate laminate, n a thin slice of porcelain or plastic fabricated in a dental lab, which is cemented to the front of the teeth to cover gaps, whiten stained teeth, or reshape chipped or broken teeth. gives design engineers more space to work with." The 3M laminate material allows designers and manufacturers of high-speed digital printed circuit boards to achieve higher speeds while simplifying design tradeoffs. When used as a power-ground core in a multilayer printed circuit board, 3M embedded capacitor material effectively becomes a decoupling capacitor A decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor reducing the effect they have on the rest of the circuit. inside the board. The material allows designers to eliminate large numbers of decoupling capacitors, increases useable board area, enables faster signaling, lowers radiated ra·di·ate v. ra·di·at·ed, ra·di·at·ing, ra·di·ates v.intr. 1.

Printed circuit board fabricators can use the material in military, automated test equipment, computer and telecommunications applications. 3M's new product offers good adhesion between the dielectric and the very smooth copper foils. 3M's improved embedded capacitance material is covered by U.S. Patent No. 6,274,224. 3M is supplying samples in limited quantities to select OEMs and fabricators for initial testing.
