Patent ID: 7640656

Claim:
A method for manufacturing a pre-molding leadframe strip with compact components, applicable to light-emitting diode components, comprising the steps of: forming a leadframe strip with an array of component regions, each component region including two metal parts for using as a chip-attached portion, a wire-bonded portion and two external electrical connection conductors; and forming a pre-molded structure on each of the component regions to surround portions of the component region on the leadframe strip with an exception of only the two external electrical connection conductors through a multiplicity of pre-molding processes; wherein the array has multiple first columns and multiple second columns arranged alternately, and the multiplicity of the pre-molding processes has a first pre-molding process implemented to process the component regions in first columns of the array, wherein adjacent first columns are at an interval of at least one component region; and a second pre-molding process implemented to process the component regions in second columns of the array, wherein adjacent second columns are at an interval of at least one component region.
