High tolerance connection between elements
This is directed to connecting two or more elements using an intermediate element constructed from a material that changes between states. An electronic device can include one or more components constructed by connecting several elements. To provide a connection having a reduced or small size or cross-section and construct a component having high tolerances, a material can be provided in a first state in which it flows between the elements before changing to a second state in which it adheres to the elements and provides a structurally sound connection. For example, a plastic can be molded between the elements. As another example, a composite material can be brazed between the elements. In some cases, internal surfaces of the elements can include one or more features for enhancing a bond between the elements and the material providing the interface between the elements.
