Test Name Conditions Standard Pb-free Solderability JESD22B-102E; Perform 8 hour steam aging for Matte tin finish and 1 hour steam aging for NiPdAu finish prior to testing. Standard Pb-free: Matte tin/ NiPdAu finish, SAC solder, wetting temp 245 C for both SMD & through hole packages. N/A 5 2 10 > 95% lead coverage Standard Pb-free solderability is the requirement. SnPb solderability (backward solderability SMD reflow soldering) is required for any plating related changes and highly recommended for other package BOM changes.
