Problems solved by technology

This composition has excellent bonding properties, and there is no shrinkage due to volatilization of organic solvents, but due to catalyst curing caused by imidazole, the strain in the cured product is large, and it cannot be said to have sufficient insulation reliability and heat resistance. Sexual substances, hope to further improve

Abstract

The present invention provides a thermosetting resin composition which has smaller solidification shrinking and excellent crack resistance and insulation reliability and the like properties, further the invention provides a thermosetting resin composition which has excellent sealing property between the condensate filled in the hole part and the cover coating layer. The thermosetting resin composition provided by the invention is characterized in that the composition comprises the following components: (A) epoxy resin, (B) polyfunctional phenolic compound, (C) solidifying catalyst, (D) filling agent and (E) the thermosetting resin composition of the oxetane compound; the invention also provides a thermosetting resin composition containing the compound which is showed by the general formula (I) and includes the oxazine ring group.

Description

technical field [0001] The present invention relates to a thermosetting resin composition used in the manufacture of a multilayer printed circuit board and a multilayer printed circuit board using the composition. More specifically, it relates to a liquid thermosetting resin composition which is useful as a composition for permanently filling via holes, through holes, etc. of printed circuit boards such as multilayer substrates and double-sided substrates, has less cure shrinkage, and is excellent in crack resistance And a multilayer printed circuit board using the composition. Background technique [0002] In recent years, printed circuit boards have been continuously developed in terms of thinner patterns and smaller mounting areas. Furthermore, in order to correspond to the miniaturization and high performance of devices equipped with printed circuit boards, it is desired to make printed circuit boards thinner and thinner. Therefore, the printed circuit board forms a res...
