Embodiment

[0014] Embodiment: a triode

[0015] see figure 1 , comprising a substrate, a triode chip 1 connected to the substrate, and a package body 2 wrapped outside the triode chip 1, the triode chip 1 includes a chip body 10 and three pins 11, and the chip body 10 packages Inside the package 2, the three pins 11 are connected in parallel to the lower end of the package 2, and are respectively connected to the base, emitter and collector of the chip 1; the pins 11 are made of copper, aluminum, zinc and nickel It is alloyed according to the weight ratio of 15~25:2~3:1~1.5:0.5, and the outer surface of each pin 11 is plated with a tin layer; the three pins 11 mentioned above, each pin 11 The diameters of the pins 11 are the same, and there is a distance between two adjacent pins 11, and the length ratio of the diameter to the distance is 1:4~6.

[0016] Specifically, the pin is alloyed with copper, aluminum, zinc and nickel in a weight ratio of 20:2:1:0.5.

[0017] In addition, a pin...

Abstract

The invention relates to a triode, which comprises a substrate, a triode chip connected with the substrate and a packaging body coated outside the triode chip, wherein the triode chip comprises a chipbody and three pins, the chip body is packaged inside the packaging body, the three pins are connected at the lower end of the packaging body in parallel, the pins are formed by alloying copper, zincand nickel according to a weight ratio of 15-25:1-1.5:0.5, and the outer surface of each pin is plated with a tin layer. The pins of the triode are formed by alloying copper, zinc and nickel according to the weight ratio of 20:1:0.5, so that the pins of the triode are enabled to have certain toughness through the special weight ratio setting. In addition, the pins of the triode are not easy to bebroken and not easy to be corroded.

Description

technical field [0001] The invention belongs to the field of electronic components, in particular to a triode, in particular to a triode. Background technique [0002] As we all know, the role of the triode is to amplify weak signals into electrical signals with larger amplitudes. It is widely used in radio, television, communications, radar, calculators, automatic control devices, electronic instruments, household appliances and other fields. [0003] However, the existing triode is usually provided with a lead frame, and aluminum wires are drawn out from the lead frame as pins of the triode. Such pins are easy to mix with each other, easily lead to breakage, and are easy to corrode, which cannot guarantee hardness, toughness, and corrosion resistance at the same time, and damaged triodes will directly affect the normal use of electrical appliances. [0004] Therefore, proposing a triode is the research subject of the present invention. Contents of the invention [0005...
