Embodiment Construction
[0019] Such as figure 1 Shown is a structural schematic diagram of the tire pressure sensor packaging lead frame.
[0020] A tire pressure sensor packaging lead frame is used for fixedly connecting a tire pressure sensor chip, a main control chip and a transmitting chip; it includes a frame body, and the frame body is made of nickel-palladium-gold material.
[0021] The frame body includes a first base island 101, a second base island 102, a first lead wire 104 and a second lead wire 103; the first base island 101 and the second base island 102 are arranged on the The center of the frame body; the first base island 101 is used to install the main control chip and the emitting chip; the second base island 102 is provided with a through hole in the center, and the through hole is used to sense the external air pressure. The second base island 102 is used to fix the tire pressure sensor chip; the first lead line 104 is T-shaped, and the first lead line 104 is arranged on opposit...
