Drying: It is recommended that after washing these modules be dried at 100 ×C for a minimum of 10 min and
possibly more depending on use (see below).
Power Module PEM Stud use:
1) For module applications using the PEMs in any way, the drying time at 100 ×C should be increased to 30
minutes since liquid is more prone to enter any stress fractures induced between the PEMs and the potting
compound during fastener insertion and tightening.
2) The PEMs are specifically intended to enable mounting heat sinks onto the top surface of the module with
fasteners inserted through the heat sink.
3) It is recommended that threaded objects or other components not be inserted into the threaded PEMs from
the under-surface side of these modules. Objects inserted at the underside can lead to cleaning solution
entrapment in the fastener hole area and subsequent ingestion of the liquid into the module and failure. If such
objects or attachments are used, then the drying method of 100 ×C for longer than 30 minutes may be required
for adequate liquid purging.
PEM torque: Maximum fastener/ PEM stud torque when attaching items from the heat sink mounting surface is
5.0 in lbs.; Maximum fastener/ PEM stud torque when attaching items from the potting surface is 2.5 in lbs.
