Patent ID: 7204017

Claim:
A manufacturing method of a modularized leadframe comprising: (a) selecting multiple metallic block leads forming at least an arrangement of two rows; (b) contacting and holding the upper surface of row of multiple leads with the inner surface of a first mold set, contacting and holding at least a selected surface on the lower part of the leads with the inner surface of a second mold set, wherein the second mold set has a protruding part which is positioned between the leads of each row of lead and contacting an upper surface of the protruding part with the inner surface of the first mold set during the holding so as to leave a space for bonding a wire connecting a chip and the lead after removing the two mold sets; (c) injecting packaging materials into the space formed between the two mold sets, forming an encapsulated body in which the leads are fixed and packaged; removing the first and the second mold sets to leave the space between the leads for bonding the wire connecting chip and the lead; wherein at least the upper surface of the leads and at least the lower surface of the leads are exposed and the exposed upper surface is provided for placing the chip and part of the exposed lower surface is provided for bonding a conductive wire with the chip and part of the exposed lower surface is provided for soldering with a printed circuit board (PCB).
