Question
On checking the follow part ADXL330KCPZ on your web site when we view the
'Material Declaration From' we notice under the 'Plating or solder Sphere
finish' it states 'E3 with RoHS Exception' but in other locations you state
the 'Z' in the part no indicates it is RoHS compliant this is causing some
confusion in our manufacturing plant.
Can you please advise what 'E3 with RoHS Exception' relates to?
Answer
E3 means the Pb used in the part is necessary due the nature of the process and
therefore exempted from Pb free regulations.
It is the glass seal from the LCC package that requires Pb in a process due to
300C resistance.
