Embodiment 1

[0016] A processing technology for a positive temperature coefficient sensor, comprising the following steps:

[0017] (1) Cut the wires, use the wire cutting machine to cut the cables to ensure that the length of each cable is the same;

[0018] (2) Peel the outer skin, use a pneumatic stripping machine to peel off the outer skin at both ends of the cable;

[0019] (3) Stamping of metal pins. Firstly, the metal pins are stamped into strips. After stamping, they are rewound with a reel; (4) Electroplating. The metal pins after stamping and rewinding are electroplated. After the electroplating is completed , use the reel to rewind; (5) terminal stamping, stamp the terminal on the punching machine, and connect the terminal and the cable by stamping; (6) weld the metal pin, hit a little at the intersection of the metal pin and the inner core of the cable Flux, tin soldering time is controlled within 1-2 seconds;

[0020] (7) Clean the silicon wafer and thermally oxidize the sur...

Abstract

The invention discloses a machining technology of a positive temperature coefficient sensor. The machining technology comprises the first step of wire cutting, the second step of outer skin peeling, the third step of metal plug pin punching, the fourth step of electroplating, the fifth step of terminal punching, the sixth step of metal plug pin welding, the seventh step of silicon wafer cleaning,the eighth step of metal plug pin injection molding, the ninth step of framework injection molding, the tenth step of circuit board installation and welding, the eleventh step of cover plate assembling, the twelfth step of detection and the thirteenth step of dispensing. The preparation process is simple and scientific, the surface precision of the patch area is high, the sticking position of a strain gauge is accurate, the sensitivity of the sensor is high, and electric signals can be input and output effectively; and the efficiency is greatly improved, the product quality is stable, the requirement of customers for the production capacity can be met, the product manufacturing cost can be reduced, cost advantages are obvious in the aspects of punching, electroplating and the like, the forming period can be greatly shortened, the yield is high, and the effect is obvious.

Description

technical field [0001] The invention relates to the technical field of sensor processing, in particular to a processing technology of a positive temperature coefficient sensor. Background technique [0002] "Sensor" is defined in New Webster's Dictionary as: "A device that receives power from one system and sends power, usually in another form, to a second system." In basic subject research, sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, it is necessary to observe the vast universe of thousands of light-years at the macro level, to observe the particle world as small as fm at the micro level, and to observe the evolution of celestial bodies that last hundreds of thousands of years vertically , an instantaneous response as short as s. In addition, various extreme technology researches, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong...
