One-piece aluminum flexible circuit board with support layer switching function and preparation technology

Abstract

The invention relates to the technical field of flexible circuit boards, in particular to a one-piece aluminum flexible circuit board with a support layer switching function and a preparation technology. The one-piece aluminum flexible circuit board comprises a one-piece flexible circuit board, a thermosetting adhesive, a one-piece aluminum reinforcing body and a supporting film, wherein the one-piece flexible circuit board consists of a plurality of flexible circuit board bodies and a frame; the flexible circuit board bodies are positioned inside the frame; gaps are formed between the flexible circuit board bodies and the frame; the bottom of the one-piece flexible circuit board and the top of the one-piece aluminum reinforcing body are bonded by using the thermosetting adhesive; and the bottom of the one-piece aluminum reinforcing body is adhered with the supporting film. Compared with the prior art, the one-piece aluminum flexible circuit board structure with the support layer switching function is designed, the flexible circuit board bodies are taken out from the supporting film when the structure is used, the supporting film has the advantages of high supporting degree, low viscidity for a non-cohesive gel and high temperature resistance, the surface packaging assembly accuracy of the product is met, and the product size stability and the consistency of product size accuracy are guaranteed.

Description

technical field [0001] The invention relates to the technical field of flexible circuit boards, in particular to a whole-board aluminum flexible circuit board with a load-bearing layer transfer function and a preparation process thereof. Background technique [0002] Nowadays, LED lamps have been gradually popularized and applied to automobile lamps. The three-dimensional assembly and excellent lamp holder support of the product structure after the combination of flexible circuit boards and metal reinforcements are more and more widely used in automobile lamps. Due to the different shapes and irregular height differences of the automotive lamp circuit board during the surface packaging and lamp holder bracket assembly process, the existing flexible circuit boards have the following defects: [0003] The existing metal reinforcement is bonded to the body of the flexible circuit board one by one with 3M glue. This bonding method not only has low production efficiency, but also...
