Abstract

The invention relates to aluminum-nickel welding belt, which comprises connected thin aluminum belt and thin nickel belt to form complex layers structure; particularly, both the top and lowest layers of welding belt are thin nickel belts. This invention can realize easily the fusion welding between the said belts with high strength, reliable effect.

Description

【Technical field】 [0001] The invention relates to a component of an electronic component, more specifically, the invention relates to a lead-out wire of an electronic component and a production process thereof. 【Background technique】 [0002] Currently on the market, some electronic components need to use aluminum or aluminum alloys as conductors or electrodes inside. Although aluminum is a metal material with good electrical conductivity and very cheap, the crystal phase structure of aluminum is very loose. In the exposed air environment, aluminum conductors are very easy to form a dense oxide layer on the surface. Although this layer of dense oxide layer can prevent the deep aluminum from being further oxidized, it also makes aluminum or aluminum alloy conductors, It is difficult for the electrodes to be directly welded to the pins and electrodes of circuit boards, wires or other electrical components by simple soldering tools. In order to overcome the above shortcomings, ...
