Problems solved by technology

[0004] The above structures are all bonded and fixed with PP sheets, but the disadvantages of using PP sheets are: since the whole process of hot pressing of PP sheets takes 2.5 hours, the efficiency is relatively slow, and it is easy to produce bad phenomena such as whitening
The defect rate is higher, so the overall product cost is higher

Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Such as figure 1 As shown, a hard copper bar for a 5G base station cable includes a first epoxy plate layer 1, a first PI film layer 2 with hot melt adhesive, a first copper plate layer 3, and a second tape layer arranged sequentially from top to bottom. Hot melt adhesive PI film layer 4, the second epoxy board layer 5, the third hot melt adhesive PI film layer 6, the second copper board layer 7, the fourth hot melt adhesive PI film layer 8 and the third epoxy board layer 9.

[0036] Further, the thicknesses of the first PI film layer with hot melt adhesive 2 , the second PI film layer with hot melt adhesive 4 , and the third PI film layer with hot melt adhesive 6 are all 0.2 mm to 0.3 mm.

[0037] Further, th...

Abstract

The invention provides a 5G base station cable hard copper bar and a processing technology thereof. The 5G base station cable hard copper bar comprises a first epoxy plate layer, a first hot melt adhesive PI film layer, a first copper plate layer, a second hot melt adhesive PI film layer, a second epoxy plate layer, a third hot melt adhesive PI film layer, a second copper plate layer, a fourth hot melt adhesive PI film layer and a third epoxy plate layer which are sequentially arranged from top to bottom. According to the invention, a PP sheet in the prior art is replaced, the PI film with the hot melt adhesive is used as the bonding layer, and curing can be realized only by performing hot pressing at the hot pressing temperature of 170 to 190 DEG C for 12 to 17 minutes, so that the hot pressing curing time of the copper bar is greatly shortened.

Description

technical field [0001] The invention relates to the field of 5G base stations, in particular to a 5G base station cable hard copper bar and its processing technology. Background technique [0002] In the prior art, an outdoor base station is disclosed to be stacked into a busbar, the publication (announcement) date: 2020-08-11, and the publication (announcement) number: CN211239231U. It includes the first prepreg, the first copper bar, the first insulating layer, the resin board, the second insulating layer, the first copper bar and the second prepreg which are arranged sequentially from top to bottom, and the third prepreg is arranged on the between the first prepreg and the first copper bar. The third prepreg can effectively prevent the first copper bar from shaking inside the resin board. The bonding between the resin plate and the copper bar uses a prepreg, and the prepreg is also called "PP sheet", which is one of the main materials in the production of multilayer boa...
