Abstract: A component having a boundary element is disclosed. In an embodiment a component comprises a semiconductor chip, a housing and a reflective layer, wherein the housing has a shaped body and a base body, the shaped body laterally enclosing the base body at least in places and being different from the reflective layer. In a plan view, the base body has a free area which is uncovered by the shaped body. The free area or a bottom surface of a cavity comprises a mounting surface for the semiconductor chip, wherein the semiconductor chip is arranged on the mounting surface. The bottom surface or the free area is partially covered by the reflective layer, wherein the mounting surface is enclosed at least in regions by a boundary element which adjoins the reflective layer and is configured to prevent the semiconductor chip from being covered by the reflective layer.

Abstract: Crimping of an LED leadframe to a subassembly may stress the leadframe. Flat leadframes cannot accommodate these stresses. Strain relief sections are added to the leadframe to accommodate crimping or other stresses on the leadframe. Strain relief sections are created in the leadframe in the form of openings, notches or bulges. The strain relief sections may be symmetric or asymmetric.

Abstract: A leadframe (610) is formed that simplifies the packaging of light emitting elements and/or eliminates the need for stress-inducing folding after encapsulation. In particular, the folding of the contact tabs (505, 506) for surface mounting is performed prior to the mounting and encapsulation of the light emitting elements on the leadframe. In an example embodiment, the leadframe may be formed so that an array, or matrix, of light emitting elements may be packaged during a single packaging process.
