Description

Plasma surface treatment device for flexible circuit board

Technical Field

The utility model belongs to the flexible circuit board field, concretely relates to flexible circuit board plasma surface treatment device.

Background

With the rapid development of electronic technology, the demand and the daily increase of 3C electronic products have driven the technological innovation of a new generation of electronic packaging technology, flexible circuit board, which has high density, small volume and can be freely mounted and dismounted. The flexible circuit board, namely the FPC, as a special electronic interconnection technology, has the characteristics of light weight, thin thickness, short assembly time, small volume and flexible structure, and has wide applicability.

An alternating high frequency high voltage is applied to two ends of the electrode, so that the air between the two electrodes generates gas glow discharge to form plasma. The plasma comprises ions, electrons, excited free radicals and the like, the energy contained in low-temperature plasma particles is greater than the binding bond energy of a polymer material, and the chemical bonds of the organic high polymer can be effectively broken; but its energy is lower than that of the radioactive rays and therefore does not affect the properties of the matrix. Through the low-temperature plasma surface treatment, the surface of the material undergoes various physical and chemical changes, or is etched and roughened, or a dense cross-linked layer is formed. The application of plasma surface treatment to the surface treatment of the flexible circuit board comprises the following steps: cleaning, activating, removing drilling dirt, pitting and carbide.

The existing plasma surface treatment device for the flexible circuit board can only treat one flexible circuit board at a time, and the working efficiency is low.
