Embodiment 1～11

[0107] (Examples 1-11, Comparative Examples 1-4)

[0108] According to the formula shown in the following table, measure the specified amount of each resin (A-1, A-2, A-3, B-1, B-2, B-3, B-4 and B- 5) and a specified amount of toluene. Next, after heating and dissolving the mixture of the resin and toluene using a heating stirrer, it was cooled to room temperature. Next, predetermined amounts of imidazole compounds and the like (C-1, C'-1, C'-2, C'-3, and C'-4) are thrown into the mixture. Then, the obtained mixture of (A) component, (B) component, and (C) or (C') component was stirred and mixed with a self-rotating or revolving mixer (MAZERUSTAR (trade name), manufactured by Kurabo Bosho Co., Ltd.) 3 minutes, thereby preparing a resin composition. However, in Example 11, fused spherical silica filler (manufactured by Ronsen Co., Ltd. MP-15EF, average particle diameter: 1.5 μm) was also added to the resin composition as an inorganic filler, and then, using a bead mill, The...

Abstract

The present invention provides a substrate having excellent adhesive strength to substrate materials such as metal foil and polyimide contained in the wiring of a printed circuit board, and has dielectric properties in a high-frequency region, specifically, a frequency of 1 to 100 GHz. A thermosetting film exhibiting a low dielectric constant (ε) and a low dielectric loss tangent (tanδ) in the region, and a resin composition used for producing the thermosetting film. The resin combination includes (A) an epoxy resin, (B) a resin having a dielectric loss tangent (tanδ) of less than 0.005 in the frequency range of 1 to 100 GHz, and (C) a carbon atom number in the 1-position of a heterocyclic ring. An imidazole compound having a side chain of an alkyl group having 5 or more.

Description

technical field [0001] The present invention relates to a resin composition, a thermosetting film using the same, a resin cured product, a laminate, a printed circuit board, and a semiconductor device. Background technique [0002] In recent years, the miniaturization, weight reduction, and performance enhancement of electrical and electronic equipment have progressed. Accordingly, printed wiring boards used in these devices, especially multilayer printed wiring boards, are required to have higher multilayer, higher density, thinner, lighter, higher reliability, moldability, and the like. In addition, with the recent demand for higher speed of transmission signals on printed circuit boards, the high frequency of transmission signals has been significantly advanced. Therefore, materials used for printed wiring boards are required to be able to reduce electrical signal loss in a high-frequency region, specifically, a region with a frequency of 1 GHz or higher. [0003] For i...
