PBF INFO:
Terminal Finish Part Marking
IPC/JEDEC Joint Standard J-STD-609A.01 defines various categories describing the terminal finish or solder ball material of components with symbols e0 through e9. LTC currently uses the following:Pb-containing
e0 – contains intentionally added Pb
Pb-free
e1 – tin-silver-copper (SnAgCu) with silver content greater than 1.5% and no other intentionally added elements
e3 – tin (Sn)
e4 – gold (Au)
The symbol e0, e1, e3, or e4 is added to the product top marking of larger packages. The symbol e0, e1, e3, or e4 is marked on the same line as the date code or the trace code. There is no change to the line that contains the part number.
Lead (Pb) free packages that are too small to accommodate the e3, a "<" symbol is added to the device at the pin 1 location. Pb-free 2mm X 2mm and 3mm X 2mm packages are identified by rearranging the trace code marking of the device. These Pb-free marking indicators were implemented starting with date code 0514. However, we will continue to ship Pb-free product, from our existing stock, which was marked prior to 0514 without the indicator.
