影响电容器级钽丝脆性因素的研究
|
摘要
电容器级钽丝作为电容器的阳极引线,其化学成分、抗拉强度、硬度以及晶粒尺寸的大小等固有特性会影响钽丝的脆性。在制作钽电容器过程中,钽电容器阳极块设计的合理性、钽阳极块烧结工艺的过程控制也会影响钽丝的脆性。一旦阳极引线钽丝产生脆性,会造成引线折断,导致电容器失效,因此钽丝具有良好的固有特性,严格控制阳极块的制作过程,防止钽丝发脆、提高钽丝的弯折次数,才能得到高质量、高性能的钽电解电容器。
Capacitor grade tantalum wire as the anode lead of capacitor,its intrinsic properties such as chemical composition,tensile strength,hardness and grain size etc. affect the brittleness of tantalum wire. In process of making tantalum capacitors,the scientific design of anode block of tantalum capacitor,the control stability of tantalum anode block sintering process can affect the brittleness of tantalum wire. Once tantalum wire of anode leads to brittleness,cause the wire broken,cause the entire capacitor failure. Therefore,the tantalum wire has good intrinsic properties,by controlling the production process of tantalum anode block,preventing the brittleness of tantalum wire,further improving the bending times of tantalum wire,high quality and high properties tantalum capacitors can be achieved.
