An electronic component includes a housing and a cover. The housing includes a concave portion accommodating therein elements. The cover covers the concave portion. A laser-welded portion including a discontinuous portion is provided along a circumference of the concave portion of the housing and fixes the cover to the housing.

A housing includes a concave portion in which components are to be accommodated. A cover covers the concave portion. A first laser-welded portion is provided along a circumference of the concave portion of the housing and fixes the cover to the housing. The cover includes an opening positioned inside of the first laser-welded portion and corresponding to a part of the circumference of the concave portion of the housing.

A user interface includes a front panel that has an exterior surface and an interior surface. A flange outwardly extends from the exterior surface and defines a notch. A receiving body extends from the interior surface of the front panel that is proximate the flange. A receiving body has an angled edge and defines a drainage channel that extends through a portion of the notch that is defined by the flange.

Systems and methods are provided for handsets for testing devices with fluid ingress mitigation.

An enclosure is provided that includes a main housing, a top housing, and a front housing. The main housing defines at least a rear wall of the enclosure, the top housing defines a top wall and a pair of side walls of the enclosure, and the front housing defines a front wall of the enclosure. The top wall has a convex curved portion that spans between side walls, where the convex curved portion has an angle that slopes downward from the rear wall towards the front wall.
