Abstract
The present disclose describes a device which has particular utility in clamping printed circuit boards which are exposed to high shock conditions. This device includes a clamping bar which is permanently deformed in its fabrication process such that it assumes a curved or arcuate configuration. Employment of the clamp device involves physical contact between the edge of the printed circuit board and the bar, and the application of forces to the extremities of the latter, by mechanical fasteners to cause it to become substantially planar. The latter condition provides an evenly distributed high clamping force to the board without any high stress points which might cause board fractures. Accordingly, the present device increases the reliability of printed circuit boards as well as the electrical components mounted thereon, by providing exceptional printed circuit board rigidity.
