Abstract
The invention relates to a method for producing an electrical leadframe (), in particular for a light-emitting diode component, having at least one first electrical connection conductor () and at least one second electrical connection conductor (). The method includes a) production of a layer composite comprising an electrically insulating carrier layer () and an electrically conductive connection conductor layer (), b) patterning of the carrier layer () in such a way that at least one contact-making window () toward the connection conductor layer () is produced in said carrier layer, and c) patterning of the connection conductor layer (), in such a way that the first electrical connection conductor () and the second electrical connection conductor () are produced, at least one of which can be electrically connected through the contact-making window (). The invention also relates to a leadframe strip having a connection conductor layer and a connection carrier layer, on which an array with a multiplicity of component regions is formed, the connection conductor layer being at least partly removed along separating lines between two adjacent component regions.
