Hello Matthew,

Below is the summary of the substrate pad finish of EM21XX built by different suppliers:

The Au plating thickness on the substrate pad is: Au 0.05-0.1um or Au 0.1um (min.) depending on assembly suppliers.

  • EM2120H01QI / EM2120L01QI / EM2130H01QI / EM2140P01QI :
    • Hana assembly - Ni: 5um (min) / Au: 0.05 - 0.1um
    • Unisem assembly - Ni: 2-5um /Pd: 0.1-0.2um/Au: 0.1um (min)
    • ASEKH assembly - Ni: 5um (min) / Au: 0.05 - 0.1um

I hope this solve your question.

Thanks,

Mostafa
