Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] see figure 1 , the embodiment of the present invention includes:

[0019] A double-sided adhesive sheet for rigid-flex boards, comprising: the double-sided adhesive sheet is made by combining two adhesive sheets, and the two adhesive sheets are respectively glass resin adhesive sheets 1 and prepreg 2.

[0020] The conventional single glass resin bonding sheet 1 and the prepreg 2 have their own characteristics, but the two materials corresponding to the two base materials of the soft and hard bonded board cannot be single and meet the combined product requirements at the same time. The glass resin bonding sheet 1 The conversion temperatur...

Abstract

The invention discloses a double-sided bonding sheet for a hard and soft combined plate and a manufacturing method thereof. The double-sided bonding sheet is formed by compounding two bonding sheets which are respectively a glass resin bonding sheet and a semi-solidified sheet. The manufacturing method comprises the following steps: a) preparing materials: the glass resin bonding sheet and the semi-solidified sheet, and b) compounding: respectively heating the glass resin bonding sheet and the semi-solidified sheet to be at 180 DEG C, and then pressing the glass resin bonding sheet and the semi-solidified sheet, thereby obtaining the double-sided bonding sheet. In such a mode, the defects of insufficient bonding strength and irregular gumming of the hard and soft combined plate are overcome by the double-sided bonding sheet for the hard and soft combined plate, and the hard and soft combined plate has perfect high-temperature thermal shock resistance and stable use effect under a severe environment.

Description

technical field [0001] The invention relates to the technical field of rigid-flex boards, in particular to a double-sided adhesive sheet for rigid-flex boards and a manufacturing method thereof. Background technique [0002] Rigid-flex board is a new type of printed circuit board that combines the durability of rigid printed circuit board (PCB, printed circuit board) and the adaptability of flexible PCB. The most resistant, so it is favored by medical and military equipment manufacturers, and Chinese companies are gradually increasing the proportion of soft and hard boards in the overall output. [0003] Due to the problem of the used bonding sheet, the existing soft-hard bonding board has the defects of insufficient bonding strength, irregular flow of glue, and inconvenient bonding. Therefore, it is necessary to develop a new bonding sheet that can solve the above problems. Contents of the invention [0004] The technical problem mainly solved by the present invention i...
