In the procedures of mixing material and making the sheet for the core material of the macromolecule PTC thermistor, after the steps of the making the sheet and the irradiation, the chip is put to the heating equipment with the temp 40-80 deg.C higher than melting point of the macromolecule polymer for 4-6 hrs. Then, the chip is displaced to the freezing equipment with the temp from -20 deg.C to -60 deg.C for 1-2 hours. The proper heat treatment technique improves the crystal form, making the crystal grain become fine and even. The technical treatment also makes the conduction filling material, the inorganic non-conducting filling material and each auxiliary agent become even state. The invention raises the enenness and the coherence of the performances of the macromolecule PTC thermostoras well as increases the rate of finished products.

The invented core material of the macromolecule PTC thermistor consists of the chip possessing the PTC characteristics and the metals foil electrodes pasted on the both sides of core material. The area of the electrode is smaller than the area of the chip. Comparing with the prior art, the etching technique and the stamping etc. techniques are adopted so as to realize the new structure of the PTCthermistor: the large chip and the small electrodes. The new structure increases the creepage distance between the electrodes, and reduces the arc discharging phenomena happened between the electrodes.
