ABSTRACT:
A stripline launcher spring washer exerts a constant force between a circuit board and stripline launcher hardware keeping the launcher and all of its hardware tight as the circuit board expands and contracts due to temperature variations. The stripline launcher spring washer has a plurality of slotted screw holes with each slotted screw hole capable of housing an individual screw. Upon expansion of the launcher hardware assembly, the washer provides a clamping force either outside or inside of the plurality of slotted screw holes depending on the washer's embodiment.
