Problems solved by technology

[0003] 1. Manual plug-in, manual welding, low work efficiency;
[0004] 2. The lead wire is easy to deform, and the efficiency is low when customers use it;
[0005] 3. The encapsulation material is easy to drop slag, which affects the welding quality;
[0006] 4. The pins of the common terminal and the pressure-sensitive terminal need to be marked with "K" pins, so the top of the product is high and requires a large space;
[0007] 5. The lead wire is long, and the customer needs to cut the pin again

Abstract

The invention discloses a method adopting a stereoscopic metal belt technology for producing a thermal pressure-sensitive resistor and products thereof. According to the invention, pins fixed through a metal belt to form a stereostructure are adopted; a positioning device is not required during production; the sizes of the pins conform to the design requirements; compared with the situation that pins are cut for three times in the conventional process, that the pins are cut for two times is required, and the working efficiency of pin cutting is improved by more than 50 %; all the pins adopt sheet structures; the pins of the products are not easy to deform; the problem that slag is easy to fall from coating material is solved; a bulk packing way can be adopted for packaging, so that the packing cost, the transportation cost and the labor cost can be reduced; K-shaped pins are not required to be made for products; the height of the product top is low; the use is convenient.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a method for producing a thermal varistor by using a three-dimensional metal strip process and a product thereof. Background technique [0002] At present, the process of producing composite thermal varistors is to weld the varistor chip and thermistor chip together through hot air current carrying, which is an eccentric composite chip, such as Figure 12 As shown, manually insert the composite chip on the paper tape 1, weld the common terminal pin and the pressure-sensitive terminal pin manually with electric chromium iron or machine, and then manually insert the heat-sensitive terminal pin on the paper tape 2 Weld it on the thermistor chip, cut off the lead wire of the thermistor terminal pin number from the braid 2, encapsulate and solidify → mark the word → cut the end of the braid lead wire → withstand voltage → final check resistance value / varistor voltage → cut Comm...
