The invention discloses an insulating
corrosion-resistant bonding wire with an inorganic amorphous
coating. The bonding wire comprises a bonding wire substrate and an inorganic amorphous plating layer, and the inorganic amorphous plating layer is composed of the following components in percentage by weight: 40%-60% of SiO2, 15%-30% of Al2O3, 10%-25% of B2O and 0.1%-5% of Li2O. The bonding wire provided by the invention has higher
corrosion resistance and
vulcanization resistance, high tensile strength and good routing operation performance, and does not influence the bonding property of
welding of the substrate bonding wire and a
chassis; by using the method, the arc height can be reduced, the insulating
corrosion-resistant inorganic amorphous plating layer can enhance the adhesion betweenthe wire and glue in the packaging process, the
welding reliability is improved, the harmful substances such as C and S cannot be generated, and the corrosion resistance is far higher than that of anorganic
coating; compared with
palladium plating,
gold plating and other
metal plating materials, the bonding wire is low in preparation cost, wide in application range, free of
pollution to the environment and suitable for the
integrated circuit and
LED packaging industry.
