Abstract
A method and apparatus are provided for preventing warpage of printed circuit boards (PCBs) for the purpose of maintaining proper shape and alignment. A PCB is placed on a base of matching shape and slightly larger size. The PCB is secured to the base by a single fastener, preferably through approximately its center. Inwardly curving brackets are mounted along the outer edges of the base in such a way that their central portions rest on top of the PCB. The brackets are constructed of a solid yet flexible non-conducive material and are fastened to the base and, optionally, to each other. The PCB placed in between the base and the brackets is able to expand without warping significantly. This method is especially effective when used to maintain the shape and alignment of the PCB for an antenna.
