The invention discloses a T0263 double-row frame, and the frame comprises a double-row frame body; the double-row frame body is composed of two frame sets, the two frame sets are fixedly connected through a plurality of evenly-distributed connecting pieces, and each frame set is composed of a plurality of basic frame units and side bands. According to the invention, two basic frame units which areoppositely arranged end to end are arranged in the longitudinal direction of each of the two frame sets in the frame, and the cooling fins of the basic frame unit on one side are connected with the cooling fins of the basic frame unit on the other side; the utilization rate of raw materials is increased by 50%, waste materials are reduced, and the unit price is reduced; due to the fact that the cooling fins of the two basic frame units are connected together, the cooling fins of the two basic frame units and the base island can be bent and formed at a time; under the same equipment configuration, the capacity is greatly improved, and through the positioning grooves, lamination of the lead frame in the later storage and packaging process is facilitated.
Description
technical field [0001] The invention relates to a lead frame, in particular to a T0263 double-row frame, which belongs to the technical field of semiconductor elements. Background technique [0002] As the chip carrier of the integrated circuit, the lead frame is a key structural part that realizes the electrical connection between the lead-out end of the chip's internal circuit and the external lead by means of a bonding material, forming an electrical circuit. It acts as a bridge connecting the external wire. Plastic-encapsulated lead frames are required in most semiconductor integrated blocks, which are important basic materials in the electronic information industry. [0003] In the existing lead frames, only a single frame unit is connected to the side bands on the upper and lower sides of most lead frames, and most of the space on the raw materials cannot be used, resulting in a large amount of waste in the production process. The output is low and the cost is high, a...
