LM2904B-Q1: Plating Materials

Hi Giuliano,

Giuliano Calsavara said:

Plating Materials & Thicknesses (inner layer(by%)/outer layer(by%))
[e.g., Ni 0.001-0.002µm/(98%Sn-2%Bi) 0.010-0.20µm]

The table above is specified in %wt, but not thickness, This is done via electrochemical plating method, the Au plating is thin, Ni coating is the thickest, and Pd's plating thickness is between Ni and Au coatings. 

If you have other questions, please let me know. 

Best,

Raymond

See [FAQ] What is the thickness of Gold (Au), Palladium (Pd), or Nickel (Ni) for TI's NiPdAu lead finish?

Hi Clemens, 

Thanks for the help! - the lead frame coating thickness information.

Best,

Raymond
