The PCN# 20170804000C states a change in the material of the lead finish - NiPdAU (E4) and Matte Sn (E3)
a. Can customer used part# of both finishes inter-changably w/o making production line changes?
b. customer has been using the E4. Body marking does not show E4. However, the newly introduced Matte Sn (E3) finish shows a E3 marking on the body. Is there a PCN to show this marking inclusion?
Thanks in advanced.
