Abstract: An enclosure for an electronic device includes one or more surface features that account for manufacturing tolerances associated with the enclosure. The enclosure includes a first portion and a second portion that mates with the first portion. The surface feature extends from a contact surface of the first portion of the enclosure and acts as a contact point between the first portion of the enclosure and the second portion of the enclosure. The surface feature helps ensure each portion of the enclosure remain in contact, which provides the electronic device optimal protection from electrical interference.

Abstract: An apparatus for dampening movement of passivation material in an electronic module and a method for manufacturing an electronic module incorporating such an apparatus are disclosed. The apparatus includes a housing defining a cavity sized to contain an electrical circuit and a non-solid passivation material. The apparatus further includes means for limiting movement of the passivation material within the cavity in at least one direction. In a preferred embodiment, the limiting means comprises at least one dam.
