Abstract: A mounting for a large printed circuit board having a widespread number of short projections extending out from a surface to be supported. A slice of easily impressionable rigid foam plastic is sandwiched between the printed circuit board and a base of rigid metal. The projections are impressed into the plastic foam to provide retaining cavities, and a series of screws extend through said board at a margin closely adjacent its edge, extending through the foam and into the base.
