Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like figure 2 As shown, this embodiment describes the transverse infiltration method with the help of the applied prepreg infiltration device. The above prepreg can be selected from glass fiber cloth, fiber paper or fiber fabric; wherein, in this embodiment, the sizing tank There are 3 guide rollers in total, namely the first guide roller 20, the second guide roller 21 and the third guide roller 22; the prepreg 30 is sent longitudinally to the bottom of the glue tank 10 filled with resin glue, and then wound around On the first guide roller 20, the second guide roller 21, and the third guide roller 22, and the first guide roller 20 and the third guide roller 21 are located on a longitudinal row A, and the second guide roller 21 is located on another longitudinal row B Above, the longitudinal row A and the longitudinal row B are vertica...

Abstract

The invention relates to a pre-preg material horizontal infiltration method, which is applied to the pre-preg field of the production using the pre-preg in a copper clad laminate, the method is that the pre-preg material is vertically sent to the downside in a glue applying groove containing resin glue, and is horizontally staggered and wound on a guide roller in the glue applying groove; under the drive of the guide roller, the pre-preg material is infiltrated horizontally from the downside to the upside in the glue applying groove through the guide roller, and then passes through an extrusion roller to enter into a glue applying furnace; because the pre-preg material horizontality causes the stay time of the pre-preg material in the resin glue in the glue applying groove to be greatly increased, the time that the resin glue replaces the bubbles in the pre-preg material is prolonged, and the pre-preg material is fully infiltrated, thereby ensuring the resin glue in the glue applying groove to be able to be better infiltrated into the pre-preg material so as to reduce the solvent or bubble residue quantity in the pre-preg material in the pre-preg, and increasing the reliability of the pressing quality, and the metal-resistance ion migration, etc. of the copper clad laminate. The operation of the method is convenient, in particular the device investment cost is not added, and the industrialization application is easy to be realized.

Description

technical field [0001] The invention relates to the field of prepreg used in the production of prepregs in copper clad laminates, in particular to a method and device for lateral infiltration of prepregs, so as to enhance the wettability of prepregs. Background technique [0002] Copper clad laminate is the basic material of PCB. It is generally made of epoxy resin adhesive, glass fiber cloth (glass fiber paper, etc.), and copper foil. Since the quality of the copper clad laminate will directly affect the performance of the PCB, and the copper clad laminate is mainly determined by the prepreg, in which the prepreg (glass fiber cloth, fiber paper or fiber fabric) and the epoxy resin adhesive are used during the processing of the prepreg. Infiltration between is particularly important. [0003] like figure 1 , shows a conventional prepreg impregnation device; a plurality of guide rollers 2 are arranged up and down in the glue tank 1, and the prepreg 3 passes through the resi...
