Multi-functional flexible conductor circuit board and production method thereof

Abstract

The invention discloses a multi-functional flexible conductor circuit board which comprises a conductor and covering films. The conductor is formed by precisely punching and manufacture according to a designed circuit diagram; the covering films are respectively attached to both sides of the conductor so that the surface of the conductor is insulated from a circuit in the conductor. A production method of the multi-functional flexible conductor circuit board comprises the following steps: (1), punching a precise die; (2), pasting the films; (3), rapidly pressing (curing) within 90 seconds to 150 seconds; (4), carrying out the anti-oxidation treatment of the exposed surface of the conductor; (5), punching the profile of the die to integrate a product; (6), detecting; and (7), packaging. The multi-functional flexible conductor circuit board does not plate the conductor so as to be more environment-friendly, has simple production method and is simple to popularize the technology.

Description

technical field [0001] The invention relates to a circuit board, in particular to a multifunctional flexible conductor circuit board and a production method thereof, belonging to the field of electrical technology. Background technique [0002] Traditional soft row (FPC) circuit boards include base material, copper clad foil and cover film. The circuit is obtained by corrosion, and finally electroplated to insulate the surface of the circuit copper foil; it is usually made through the following processes: 1) cutting; 2) Mechanical drilling; 3) Film attachment; 4) Exposure; 5) Imaging; 6) Etching; 7) Stripping; 8) Film attachment; 9) Pressing at a speed of 2.5 hours to 3 hours; Inspection; 12) Packaging. The production process of this kind of traditional circuit board is complicated; the practical range has a certain space limit, and the traditional circuit board can only withstand the current conduction of relatively small voltage; the production equipment is expensive, the...

AI Technical Summary

Problems solved by technology

The production process of this kind of traditional circuit board is complicated; the practical range has a certain space limit, and the traditional circuit board can only withstand the current conduction of relatively small voltage; the production equipment is expensive, the technical threshold is high, and the price of a simple production process equipment is far away. More than 2.5 million yuan; electroplating (tin, silver, and gold plating) is commonly used on the surface of products, which is not environmentally friendly and may easily cause metal pollution to the environment
