Embodiment 1

[0022] Embodiment one, such as figure 1 As shown, the double-sided copper-clad substrate structure for the LED flexible light bar of the present invention is a three-layer layered structure, which is a copper foil layer 1, a thermosetting adhesive layer 2, and a copper foil layer 1 from top to bottom; The copper foil layer 1, the thermosetting adhesive layer 2 and the copper foil layer 1 are pasted together from top to bottom. Further, the copper foil layer 1 is one or both of electrolytic copper foil or rolled copper foil, for example, both copper foil layers 1 are electrolytic copper foil or rolled copper foil, or one of the copper foil layers 1 is electrolytic copper foil, and another layer of copper foil layer 1 is rolled copper foil. Further, the thickness specification of the copper foil layer 1 is 1 / 3oz~2oz. Further, the thermosetting adhesive layer 2 is one of epoxy modified adhesive layer, acrylic adhesive layer and silicone modified adhesive layer, which has the ad...

Embodiment 2

[0024] Embodiment 2, the manufacturing method of the double-sided copper-clad substrate for LED flexible light strips is: firstly coat a layer of epoxy-modified adhesive, acrylic adhesive or silicone-modified adhesive on the surface of copper foil, and then form a semi- After curing the adhesive film, press it with another copper foil, and finally form a double-sided copper clad LED flexible light bar with a three-layer structure of copper foil layer 1, thermosetting adhesive layer 2 and copper foil layer 1 from top to bottom. Substrate. Further, the copper foil layer 1 is one or both of electrolytic copper foil and rolled copper foil, and the thickness specification of the copper foil layer 1 is 1 / 3oz~2oz. Further, the thickness of the copper foil layer 1 is 12um~70um. Further, the thickness of the thermosetting adhesive layer 2 is 10um~100um.

[0025] In Example 2, the epoxy-modified adhesive is prepared from the following mass ratios of raw materials: epoxy resin (20%-40%...

Abstract

The invention relates to technical field of LED flexible strips, and especially relates to a double copper-coated surface base material structure for a LED flexible strip and a manufacturing method thereof. The double copper-coated surface base material structure for a LED flexible strip has a three-layer structure comprising a copper foil layer, a thermosetting adhesive layer and a copper foil layer orderly arranged from top to bottom, wherein the copper foil layer, the thermosetting adhesive layer and the copper foil layer are bound together from top to bottom. The double copper-coated surface base material structure has performances satisfying LED strip use requirements. The manufacturing method has a high yield, simple processes and a low cost.

Description

technical field [0001] The invention relates to the technical field of LED flexible light strips, in particular to a double-sided copper-clad base material structure and a manufacturing method for LED flexible light strips. Background technique [0002] In recent years, LED strip lights have been widely used in various places, such as the lighting of the walls of corporate buildings, the lighting of government buildings, the lighting of walls of historical buildings, the decoration of entertainment venues, and night scene projects. The scope involved is also getting wider and wider. With the rapid development of the LED lighting industry, the demand for flexible copper-clad foil substrates is increasing, especially in the fields of landscape, flexible lighting and low-power LEDs. The currently used double-sided copper-clad foil substrate is a five-layer structure that is coated with a thermosetting adhesive on both sides of the polyimide film and then laminated with copper ...
