Abstract
A separable and reconnectable connection for electrical equipment is provided that is suitable for miniaturization in which vertical interdigitating members integrally attached and protruding from a planar portion are accommodated in control of damage in lateral displacement that occurs on mating with an opposite similar contact. Displacement damage is averted through accommodating lateral stresses by providing one or more of a conformal opposing contact, by strengthening through coating and base reinforcement and a deformable coating. The contacts are fabricated by physical and chemical processes including sputtering, normal and pulse electroplating and chemical vapor deposition. Pulse electroplating of palladium provides a dendritic deposit of uniform height, uniform rounded points and less branching. The contacts on completion are provided with a surrounding immobilizing material that enhances rigidity.
