Problems solved by technology

[0003] Diodes are often exposed when they leave the factory, which is used to cause oxidation of the metal part, which is not conducive to the storage and use of the diode. At the same time, the fusion of the metal part of the diode is not good when it is used, which is not conducive to the welding of the diode and is not convenient for the use of the diode.

specific Embodiment 1

[0019] Specific embodiment 1: as figure 1 As shown, the soldering diode of the present invention includes a diode body 3 with pins 1 on which a rosin layer or a paraffin layer is provided. The rosin layer or paraffin layer can facilitate diode welding and has the effect of soldering. In addition, it also has an anti-oxidation effect, which can prevent the metal part of the diode from being oxidized due to improper storage, which is beneficial to the use of the diode and improves the storage period of the diode. Reduce scrap rate.

[0020] A tin ring 2 is provided on the pin 1, and there are 3-5 tin rings on a single pin, and the distance between the tin ring 2 closest to the diode body and the diode body 3 is 4-4.5 mm. The tin ring 2 not only has a position-limiting function, but also can prevent the diode from falling out after being placed in the position to be soldered. At the same time, the tin ring 2 can help solder during welding, improve welding efficiency and reduce t...

Abstract

The invention discloses a weld-aiding diode. The weld-aiding diode comprises a diode body, the diode body includes pins, and the pins are provided with a rosin or paraffin layer. Each pin is provided with a tin ring. The distance from each tine ring to the diode body is 4-4.5mm. Each pin is flat at a position 2-3.5mm from the diode body. The end, far from the diode body, of each pin is conical. The weld-aiding diode has the advantages that the structure is simple, use is convenient, the diode is more adapted to welding, the working efficiency and the utilization rate are improved, and the production cost is reduced. The rosin or paraffin layer provides convenience for welding of the diode and has weld-aiding and anti-oxidation effect, a metal part of the diode is prevented from oxidation due to improper storage, the layer is conducive to use of the diode, the storage period of the diode is prolonged, and the scrappage rate is reduced.

Description

technical field [0001] The invention relates to a flux diode. Background technique [0002] Diode is one of the most commonly used electronic components. Its biggest characteristic is unidirectional conduction, that is, current can only flow from one direction of the diode. The function of the diode is a rectifier circuit, a detection circuit, a voltage stabilization circuit, and various modulation circuits. , are mainly composed of diodes, and their principles are very simple. It is precisely because of the invention of diodes and other components that we have the birth of our colorful electronic information world. Since the role of diodes is so great, how should we detect them? This component is actually very simple. Just use a multimeter to measure the reverse resistance. If the reverse resistance is small, it means that the diode is bad. If the reverse resistance is large, it means that the diode is good. For such basic components, we should firmly grasp its working pri...
