High-stability thermistor manufacturing process

Abstract

The invention discloses a high-stability thermistor manufacturing process which comprises the following steps: firstly, manufacturing an inner layer on a thermistor material, performing laser treatment on a side of a gong groove, pressing a prepreg with a copper foil, filling the gong groove with a resin, further performing laser treatment on the other side of the gong groove, pressing the prepregwith the copper foil, filling the gong groove with the resin, wrapping a thermistor inside the gong groove completely, and finally performing patterning, thereby obtaining a finished product of the thermistor. By adopting the high-stability thermistor manufacturing process, the thermistor is manufactured in modes that groove holes are formed through laser and mechanical means and the resin is repeatedly pressed and supplied, the thermistor is surrounded by the resin, very high reliability and stability are achieved, the characteristics that the resistance of a thermistor plate is increased incase of heat and large current and normal resistance is recovered after the heat and the current are recovered are met, then relatively high market requirements are met, and product diversity is achieved.

AI Technical Summary

Benefits of technology

This patented process improves how well known thermal resistors work with stable materials like epoxy or silicone rubber. It involves repeatedly punching holes into them followed by injecting liquid material around each hole for better strength without increasing its own weight over time. By doing this, these devices have improved performance and durability while still being able to handle larger amounts of power compared to traditional methods such as welded connections between terminal ends.

Problems solved by technology

This patented technical problem addressed in this patent describes how to improve upon existing techniques for producing highly reliable thermisters while maintain their effectiveness at extreme temperatures or under certain operating situations.
