Apparatus and method for utilizing commercial off the shelf circuit boards in a highly kinematic environment
A system is disclosed which utilizes a stabilization disk 30 or rigid cup containing adhesive which is bonded to an underside of a circuit board and then bolted to a chassis of a piece of military electronic equipment, so as to create a mounting location between the circuit board and the chassis where the circuit board is lacking a regular fastener receiving mounting hole therethrough.
1. A method of providing a circuit board mounting location at a point about a location on the circuit board which does not have a fastener receiving hole therethrough, the method comprising the steps of:
providing a circuit board having a front side, having electronic circuitry disposed thereon, a back side opposing said front side, and a perimeter edge;
providing a fastener coupler, with a rigid three dimensional shape, having:
a stabilization rib perimeter wall, with a top side and a plurality of adhesive exit voids therein;
a central fastener penetrating portion;
a stabilization disk planar bottom extending between said stabilization rib perimeter wall and said central fastener penetrating portion, configured in combination to retain therein two component flexible polyurethane adhesive;
coupling the fastener coupler to only the back side of the circuit board at a first location displaced from all portions of said perimeter edge and where no fastener receiving hole is located through the circuit board; and
coupling the fastener coupler to a chassis, located on the back side of the circuit board and thereby coupling the circuit board to the chassis at the first location.
2. A method for mounting a circuit board to a chassis comprising the steps of:
providing a circuit board having a first side, a parallel second side, and a perimeter edge;
providing a chassis;
providing a means for contacting adhesive, at a location not in registration with any hole through any circuit board;
disposing an adhesive on a portion of said means for contacting adhesive;
adhering said means for contacting adhesive to said first side or said parallel second side, and displaced from all portions of said perimeter edge;
mechanically coupling said means for contacting adhesive to said chassis; and
wherein said means for contacting adhesive is a circular puck shaped cup with a planar bottom.
