Leaded Millimeterwave Package
Handling and Mounting
The leaded millimeterwave package requires careful
mounting design to maintain optimal performance.
Handling
The leaded millimeterwave package is extremely rugged.
Care should be exercised when handling with metal tools.
Only personnel trained in both ESD precautions and
handling precautions should be allowed to handle these
packages.
Package Construction
The construction of the leaded millimeterwave package
consists of a metal base and ceramic walls. The
package is topped by a solder-sealed metal lid. All metal
parts are gold-plated.
Mounting Design
The leaded millimeterwave package is mounted by placing
it in a hole cut in a printed circuit board. The bottom of the
package leads should be in the same plane as the top
surface of the printed circuit board traces. The hole should
be cut as close as possible to the outer dimensions of the
package to minimize the gap between package and
printed circuit board. The gap should be no more than
0.005" (0.127 mm). The base of the package should be
mounted directly to a surface that provides a good ground
plane for the printed circuit board and provides a good
thermal ground.
Mounting the Package
The leaded millimeterwave package should be attached
to its mounting surface using a silver-filled conductive
paste epoxy or solder. Care should be taken to ensure that
there are no voids or gaps in the epoxy or solder underfill
so that a good ground contact is maintained.
Screw hardware attachment should be used in addition
to epoxy or solder in situations where additional
mechanical integrity is desired. Care should be exercised
when tightening screws because over-tightening could
deform the package base.
Connecting the Package
Connection of the package leads to the printed circuit
board traces is accomplished with solder. Attached leads
should lie flat upon the printed circuits board traces.
Package leads can be trimmed if desired.
