Abstract

Aiming at solving the technical problem that convex structures of conventional leading wire frameworks are easily deformed by force, the invention provides a leading wire framework. The leading wire framework comprises a substrate, and at least one convex structure protruding from the surface of the substrate. The substrate comprises a part zone and a resectable zone. The resection zone is located at the periphery of the part zone. The convex structure is arranged in the part zone. The resectable zone is also provided with a supporting member. The height of the supporting member is greater than the heights of the convex structures. The leading wire provided by the invention can prevent the convex structures from deforming under force.

Description

technical field [0001] The invention relates to the field of semiconductor chip packaging, in particular to a lead frame used in the semiconductor chip packaging process. Background technique [0002] As the chip carrier of the integrated circuit, the lead frame is a key structural part that uses bonding materials (gold wire, aluminum wire, copper wire) to realize the electrical connection between the lead-out end of the chip's internal circuit and the outer lead to form an electrical circuit. As a bridge to connect with external wires, most semiconductor integrated blocks need to use lead frames, which are important basic materials in the electronic information industry. [0003] A type of lead frame is currently provided, and the lead frame is mainly used to carry power chips. Since the power chip is usually equipped with a drive circuit, the drive circuit is usually welded on a PCB (Printed Circuit Board, printed circuit board) board. and fix it on the lead frame. like ...
