Abstract

The invention provides a tire pressure sensor packaging lead frame which is used for being fixedly connected with a tire pressure sensor chip, a main control chip and a transmitting chip. The lead frame comprises a frame body which is made of nickel porpezite materials. The frame body comprises a first substrate, a second substrate, first pin wires and second pin wires. The first substrate and the second substrate are arranged in the center of the frame body. The first substrate is used for mounting the main control chip and the transmitting chip. A through hole is formed in the center of the second substrate and used for sensing the outside air pressure. The second substrate is used for fixing the tire pressure sensor. The first pin wires are in a T shape and are arranged on the opposite two sides of the first substrate. The second pin wires stretch and are distributed in the length direction of the side edge of the second substrate. The first pin wires and the second pin wires are used for transmitting signals of the main control chip, the transmitting chip and the tire pressure sensor to an external device respectively. The frame body is made of the nickel porpezite materials, and a later electroplating technology is omitted. Meanwhile, the lead frame has good electrical conductivity and thermal conductivity after the nickel porpezite materials are adopted.

Description

technical field [0001] The invention relates to a lead frame, in particular to a tire pressure sensor packaging lead frame which is simple to manufacture and quick to install. 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. Most of the semiconductor integrated blocks need to use lead frames, which are important basic materials in the electronic information industry. It is mainly produced by die stamping method and chemical etching method. The manufacturing process of the traditional lead frame is complicated, and the process is complicated when installing the chip, which requires more manpower and material resources, and the lead frame is easy to shift, making it difficult to ins...
