Ferrite Core Memory Construction

Non-hardening dielectric resin sprayed over an assemblage of ferrite cores wired in place over a ground plane improves both physical and electrical characteristics of the memory.

The resin cements the cores 1 to the ground plane 2, providing a sturdy mechanical bond. This mechanical bond maintains each of the core windings in a fixed dimensional relationship with the ground plane and thus standardizes the capacitance and inductance for each winding.

The mechanical bond also keeps cores from bouncing and cutting through the insulation of the windings. The dielectric nature of the resin helps increase capacitance between windings and the ground plane, reducing impedance of the windings. The resin also protects against corrosion.

The resin, since it is non-hardening, is effective in damping magnetostrictive ringing of the cores.
