Electronics packaging assembly with parallel circuit boards and a vibration stiffener

摘要

An electronics packaging assembly ( 100 ) includes: an assembly housing ( 120 ); a plurality of printed circuit boards ( 110; 210 ) arranged in parallel within the assembly housing ( 120 ); and a vibration stiffener ( 140; 240 ). The printed circuit boards ( 110; 210 ) each have a notch ( 112; 212 ) on one edge. The vibration stiffener ( 140; 240 ) is arranged within the assembly housing ( 120 ) along a lateral direction relative to the plurality of printed circuit boards ( 110; 210 ) and includes a plurality of slots ( 142; 242 ) that engage with corresponding notches ( 112; 212 ) of the plurality of printed circuit boards ( 110; 210 ), wherein engagement of the vibration stiffener ( 140; 240 ) with the plurality of printed circuit boards ( 110; 210 ) limits flexing of the printed circuit boards ( 110; 210 ) in the lateral direction. In one implementation, a portion of the assembly housing ( 120 ) contacts and applies pressure to the vibration stiffener ( 140; 240 ) to keep the vibration stiffener ( 140; 240 ) in place.
