    摘要: 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.

    摘要: A resin composition useful in the fabrication of circuit boards comprises (i) 1˜15 W % of bismaleimide modified by barbituric acid (BTA) and its derivatives; and (ii) 20˜50 wt % of polyphenylene ether (PPE) chain-broken in a phenol resin; wherein the phenol resin is terpene phenol resin or dicyclopentadiene phenol resin. Other additives, such as curing agent, catalyst or inorganic particle additive can be added as well, based on requirements. According to the invention, terpene novolac resin and initiator (peroxide) are added in polyphenylene ether so that molecules are rearranged to form a PPE resin having lower molecular weight and higher crosslinking density. Furthermore, BMI/epoxy resin/PPE are combined in different weight percentages. Semi-interpenetrating polymer network structures are thus formed. Consequently, Tg and resistances both to heat and solvent of the resin are increased.

    摘要: An adhesive tape for lead-on-chip (LOC) IC applications containing a polyamide-based adhesive composition which is the reaction product from a reaction mixture of: (a) a pre-imidized polyamic acid; and (b) a bismaleimide that has been modified by a barbituric acid of a derivative of barbituric acid to become a barbituric acid modified bismaleimide. The pre-imidized polyamic acid is a reaction product from a reaction mixture that contains a polyamic acid and a cyclizing agent. The polyamide-based adhesive composition provides all the desirable heat resistance and other mechanical and dielectric characteristics. But, most significantly, its microscopic rheological properties are adjusted such that excellent contact is achieved between the resin molecules and the lead frame surface while eliminating or at least minimizing the extent of adhesive overflow, which can substantially reduce the reliability of the final IC product.

    摘要: An improved polyimide-based coating composition comprising a polyimide upper layer and a polyimide-modified bismaleimide lower layer for use as a coating on metal substrate, such as an electrolytic copper foil. The polyimide are prepared from reactions between diamines, such as p-phenylene diamine and 4-4'-diaminodiphenyl ether, and dianhydrides, such as 3,3',4,4'-benzophenone tetracarboxylic dianhydride and biphenyl-3,3',4,4'-tetracarboxylic dianhydride. The modified bismaleimide can be prepared from reacting an N,N',4,4'-diphenyl bismaleimide with a barbituric acid or its derivative. A double-layered extrusion coating technique having a double-layered extrusion die is utilized to apply the coating composition onto the metal substrate. The final laminated products show improved peel strength between the polyimide coating and the substrate, as well as improved dimensional stability and surface flatness thereof.
