ORIENTATION OF MAGNETIC FILLERS TO OPTIMIZE FILM PROPERTIES

A magnetic shielding film includes opposing first and second major surfaces and a plurality of particles dispersed therebetween, each particle having a magnetic permeability, a thickness H along a thickness direction of the particle, and a longest dimension L along a length direction of the particle...

Zusammenfassung:A magnetic shielding film includes opposing first and second major surfaces and a plurality of particles dispersed therebetween, each particle having a magnetic permeability, a thickness H along a thickness direction of the particle, and a longest dimension L along a length direction of the particle orthogonal to the thickness direction, L/H greater than or equal to 2, the particles defining a plurality of voids therebetween, the length directions of at least 60% of the particles oriented within 5.5 degrees of a same orientation direction.
