  • Method of immobilizing a printed circuit board
    Patent number: 4091068
    Abstract: A hardenable material such as epoxy is placed between a circuit board edge portion and a recessed channel of a keeper member mounted on a base. The epoxy fills the space between the channel walls and the board edge portion and immobilizes the board relative to the base once it hardens. This eliminates the movement of the circuit board relative to the base. Release agent may be coated on the edge of the circuit board and the recessed channel walls of the support base so that when required, the printed circuit board can be readily and non-destructively removed from the base.
