1.
Mounting surface should be tapped for close tolerance fit
of inner to external thread.
2. Mounting surface must be flat.
3. Any bending or deformation of the package during mounting
is likely to damage the ceramic. To avoid this:
3.1. Insert all mounting screws for a
given package and tighten all finger tight.
3.2. Begin tightening screws on opposite
corners of the package to 1/3 torque
3.3. Tighten following same screw position
pattern to 2/3 torque
3.4. Tighten following same screw position
pattern to full torque
4. The use of ground or thermal pads under the package is
NOT recommended.
5. The use of low tack, ductile adhesives to improve grounding
and thermal performance has not been investigated by StratEdge.
Customers considering this mounting should consider a package
design with a thicker, stiffer base.
