The invention concerns a technique and apparatus for protecting sensitive ectronic components against the high accelerations encountered in a tank-powered projectile, for instance. A first ring is placed on a circuit board and filled with an RTV compound. A cap is placed on the first ring to force excess RTV compound from the first ring, and is removed once the RTV compound cures. A second shorter ring is placed about the RTV compound and is attached to the circuit board. A flat plate is then used to press the RTV compound into any voids which may exist between elements mounted on the circuit board. Circuit modules created in this manner may be stacked upon one another and interconnected.
