amorphous paper or Mu-metal paper can use for D/A chips for shielding or not????

[siu sin man tho]

hi,

today I received from my friend's message that can supply amphorous paper to me. It was suitable to use for D/A chips.
Is it same as the Mu-metal??
He said this can lower the digital noise & had better performance than the copper or aluminium paper.

This paper was supply from.

~National Amorphous and Nanocrystalline Alloy Engineering Research Center~

I would like to use in my parallel TDA1541a kits.
Any comment???


thanks
