Problems solved by technology

[0005] There are some disadvantages in the preparation of high CTI prepregs by using the traditional copper clad laminate production method of impregnating glass fiber cloth and other reinforcing materials with resin composition glue. Copper plates are prone to dry flowers or exposed cloth patterns; the degree of semi-curing of prepregs is not easy to control, which makes it difficult to control the resin fluidity of prepregs in the process of laminating copper clad laminates, which reduces the thickness control accuracy of copper clad laminates; use The thickness of the prepreg of the reinforcement material is large, and it is difficult to produce thin copper-clad laminates, and the storage period of this prepreg is relatively short, which is not conducive to management and control, and may easily cause material degradation

Embodiment 1

[0046] (1) Preparation of resin composition

[0047]Add 4 grams of dicyandiamide (DICY) to a clean and dry 750 ml beaker equipped with a stirrer, then add 40 grams of dimethylformamide (DMF) solvent, stir for 10 minutes to completely dissolve DICY, then add 0.200 grams of 2 -Methylimidazole, after dissolving completely, then add 80 grams of methyl ethyl ketone (MEK) to the solution, and stir and mix for 20 minutes. Then start to add 120 grams of aluminum hydroxide (the product of Martin Company in Germany, the trade name is OL-104WE) to the solution, add while stirring, slowly add all the aluminum hydroxide gradually in 2 to 3 minutes, and avoid oxidizing all the hydroxide. Pour the aluminum into the beaker at one time; after adding the aluminum hydroxide, stir and mix at high speed for 30 minutes to disperse the filler evenly. Under the condition of keeping stirring, add 60 grams of brominated bisphenol A epoxy resin (Huntsman company product, brand name Aroldite LZ8008 A80)...

Abstract

The invention relates to the technical field of copper-clad plates, in particular to a resin composition, a resin-coated copper foil produced by the same and a copper-clad plate produced by the resin-coated copper foil. The resin composition comprises the following components in percentage by weight: 45 to 80 percent of epoxy resin mixture, 15 to 50 percent of stuffing, 1 to 8 percent of curing agent, 0.01 to 2 percent of curing accelerator, and a proper amount of solvent. The resin composition is used to prepare the resin-coated copper foil, and then the resin-coated copper foil is used to produce the copper-clad plate so as to change the prior manufacturing method of copper-clad plates with high comparative tracking index and solve the technical problems of dry flowers, cloth mark exposure and inadequate thickness accuracy of the copper-clad plate and the like; the resin-coated copper foil also has the characteristics of long storage period, easy management and convenient use; and the resin-coated copper foil has a thin insulating dielectric layer, and is convenient to produce thin copper-clad plates with high comparative tracking index characteristic and multi-layer printed circuit boards.

Description

Technical field: [0001] The invention relates to the technical field of copper-clad boards, in particular to a resin composition, a resin-coated copper foil produced therefrom, and a copper-clad board produced by using the resin-coated copper foil. Background technique: [0002] Copper-clad laminate is a prepreg prepared by impregnating the reinforcing material with a resin composition, drying and semi-curing, and then covering one or both sides of the prepreg with copper foil, hot pressing and curing. A composite material, referred to as copper clad laminate (CCL), which is used to make printed circuit boards (PCB). Printed circuit boards have become an indispensable main component for most electronic products to achieve circuit interconnection. [0003] The resin composition is widely used as a material for copper clad laminates and semiconductor packaging substrates due to its comprehensive properties such as good insulation, heat resistance, mechanical properties, and a...
