Problems solved by technology

Most traditional non-flowing prepregs use rubber-toughened modified epoxy resin as the main resin material. Although prepregs with no or little flow can be obtained, the punching edge of the prepreg cracks during the mechanical punching process. Larger, which has adverse effects on the subsequent processability and heat resistance of resin materials, thus limiting its application in the preparation of multifunctional high-end printed circuit boards

Abstract

The invention provides a modified resin composition and a preparation method and application thereof. The modified resin composition is prepared from the following raw materials in parts by weight: 65-100 parts of matrix resin, 10-40 parts of phenoxy resin, 0.5-25 parts of nano silicon dioxide, 2-15 parts of a curing agent, 0-2 parts of a curing accelerator and 0-1 part of a coupling agent. The modified resin composition has the advantages of excellent toughness, excellent processability in the mechanical punching treatment process, low powder falling rate, excellent bonding performance and excellent heat resistance, can be used for preparing high-density and multi-performance printed circuit boards (PCB) with high temperature resistance, aging resistance, integrated circuit packaging, high frequency, high speed and the like, and has wide application prospects. Therefore, the development of a high-end integrated circuit is promoted.

Description

technical field [0001] The invention relates to the technical field of composite resins, in particular to a modified resin composition and its preparation method and application. Background technique [0002] With the rapid development of the electronics industry, electronic products are developing in the direction of miniaturization, multi-function and high security, requiring high-density and multi-functional printed circuit boards (PCBs), and at the same time meeting the requirements of three-dimensional installation of electronic products need. Therefore, more and more consideration is given to the use of rigid-flexible technology, that is, the technology of preparing printed circuit boards by bonding rigid circuit boards and flexible circuit boards through adhesive materials. [0003] In recent years, technicians have increasingly considered the use of non-flow adhesive prepreg as a bonding material for bonding rigid PCB boards and flexible PCB boards. No flow prepreg...
