Problems solved by technology

[0004] Based on this, it is necessary to address the fact that four-functional epoxy resins are usually used to shield ultraviolet rays when making copper-clad laminates. However, the total output of four-functional epoxy resins is insufficient. The supply is tight. In addition, the current resin composition has the problems of low optical detection efficiency and accuracy and low peel strength. To provide a resin composition with UV shielding effect and its application in copper clad laminates

Embodiment 1

[0037] See figure 1 The present embodiment provides a method for preparing a resin composition having a UV shielding action for preparing a resin composition having a UV shielding action according to any one of claims 1 to 6. The preparation method includes the steps of:

[0038] S1 uses acetone cleaning tank, and then the solvent A, solvent B, and interface binding agent are sequentially added in the end of the tank to obtain a mixed solution.

[0039] S2 adds a solid feedstock into the mixed solution, then adding the remaining raw material, stirring to obtain a gum, i.e., a resin composition;

[0040] The solid feedstock was added to the mixed solution, and the solid feedstock was completely dissolved, and then the remaining raw material was added, stirred at 1000 rpm of rotational speed, and stirred at a rotational speed of 600 rpm to obtain a glue, SGS test on the gel, qualified The gum is a resin composition. Copper plate is obtained.

Embodiment 2

[0042] This embodiment provides a resin composition having a UV shielding action. The weight component of the resin composition is as follows: 100 parts of the phenolic epoxy resin, 35 parts of high bromide epoxy resin, 10 parts of the bisphenol A epoxy resin, 80 parts of the phenolic resin, 3 of tetophenolic ethane resin, filler 150 0.2 parts of the interface binding agent, 50 butanone, 90 cyclohexanone.

[0043] Please continue see figure 2 This embodiment also provides an application of a resin composition having a UV shielding action in a coated copper. The operation of the application is as follows:

[0044] The resin composition is provided which is prepared by the preparation method as described in Example 1.

[0045] The resin composition was impregnated, baked, and a semi-solid tablet, a spare sheet was obtained;

[0046] The resin composition was placed in a vertical plexamette for impregnation, and then baked to obtain a semi-solid tablet. During impregnation, during ba...

Embodiment 3

[0051] The difference between the present embodiment and the second embodiment is in the weight component of the resin composition: 5 parts of tetheld phenolic ethane resin, and 0.035 parts of the interface binding agent.

Abstract

The invention relates to a resin composition with a UV shielding effect, and application of the resin composition in a copper-clad plate. The resin composition is used for solving the problems that the total yield of four-functional-group epoxy resin is insufficient, so that the supply of the resin is short in the peak season of the production of the copper-clad plate, and in addition, the current resin composition is low in optical detection efficiency and accuracy and low in anti-stripping strength. The resin composition is prepared from, by weight, 80 to 120 parts of novolac epoxy resin, 30 to 50 parts of high-bromine epoxy resin, 5 to 15 parts of bisphenol A epoxy resin, 20 to 100 parts of phenolic resin, 3 to 10 parts of tetraphenol ethane resin, 100 to 200 parts of a filler, 0.01 to 0.5 part of an interface bonding agent, 40 to 80 parts of a solvent A and 60 to 100 parts of a solvent B. The resin composition provided by the invention has the advantages of UV shielding effect, excellent anti-ghosting effect, argon laser absorption effect, improvement of optical detection efficiency and accuracy, increase of glass transition temperature, and high peel strength when applied to a copper-clad plate.

Description

technical field [0001] The invention relates to a resin composition, in particular to a resin composition with UV shielding effect and its application in copper clad laminates. Background technique [0002] With the development of the printed circuit board manufacturing process, photosensitive solder resist has been popularized. In order to avoid ghosting caused by the interaction between the two sides of the printed circuit board substrate during exposure, the substrate is required to have the function of shielding ultraviolet rays. At the same time, automatic optical inspection (AOI) equipment is popularized in the quality inspection during the printing process. The automatic optical inspection instrument uses argon laser as the irradiation light source. [0003] At present, four-functional epoxy resins are usually used to shield ultraviolet rays when making copper-clad laminates. However, the total output of four-functional epoxy resins is insufficient, resulting in a tigh...
