Home > Product Information : Lead frame materials(42%Ni-Fe)
•High dimension accuracy and flatness Formability in high-speed stamping
,photo etching and stability after forming.
•Good surface cleanness and surface uniformity.Excellent surface processability and adhesiveness of oxide film for high-speed plating.
•High hardness and transform resistance.
•Much closeness to coefficient of linear expansion of Si, so it is adequate to use 42%Ni-Fe in molding process.
•Precice composition control ensures the stability of product characteristics.
•Referential standards:ASTM F-30(UNS K94100)
|Modulus of elasticity||GPa||145|
|Coefficient of linear expansion(900 x 1hr)||X10-6/||4.2(30-300)|
