Packaging structure and packaging device of flexible circuit board

Abstract

The invention discloses a packaging structure of a flexible circuit board. The packaging structure comprises a packaging side cover for quickly positioning the circuit board, an integrated heat dissipation plate used for dissipating heat of the circuit board is installed on the surface of one side of the packaging side cover, and the surface of the other side of the packaging side cover is provided with a high-temperature heat conduction plate which is used for assisting the heat dissipation of the port of the circuit board. According to the invention, an evaporation chamber and an absorbent cotton block are arranged, rapid heat dissipation of the circuit board and operation of controlling the bending degree are realized in a relatively sealed environment, during implementation, once the circuit board emits heat, the heat of the conductor on the surface of the circuit board can be quickly dissipated by evaporating the moisture in the absorbent cotton block; then, the heated quick expansion table is heated to expand to extrude moisture in the absorbent cotton block; and when the space in the evaporation chamber is adjusted to be reduced by increasing the evaporation moisture of theabsorbent cotton block, the absorbent cotton block is pressed, so that the regulation and control column is pressed, and therefore, the operation of controlling the bending degree of the circuit boardcan be realized.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a packaging structure and packaging device of a flexible circuit board. Background technique [0002] Flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. [0003] During the assembly process where the flexible circuit board is embedded inside the electronic device, the flexible circuit board is easily damaged. In addition, since the flexible circuit board is exposed to the outside world without any protection, once it comes into contact with dust and moisture, the stability of the circuit operation of the flexible circuit board will be reduced. Therefore, in order to solve this problem in the prior art, the flexible circuit board It is arranged in a relatively sealed pa...
