Following
the introduction of the RoHS Directive and
the forthcoming restriction of lead in soldering materials different
process parameters are required to handle the new generation
of solder alloys and board finishes. To assist those performing
assembly, rework and repair operations the characteristics of RoHS
compliant products have been categorised by JEDEC standards under
three headings:
MSL
(Moisture Sensitivity Level), PBT
(Peak Body Temperature) and 2nd
Level Interconnect (Terminal Finish/Material).
This
vital product performance information can be obtained when using
Anglia's Part
Tracker service by clicking on the 'information icon' and is
also included on Anglia's product labelling.
The table below explains the Moisture Sensitivity Level classifications.
