PTC Thermistor Manufacturing Process
The manufacture of PTC thermistors begins with a mixture of barium carbonate, titanium oxide and other materials that produce the desired electrical and thermal characteristics, which are ground, mixed and compressed into discs or rectangles and then sintered, preferably at a temperature below 1400°C. Afterwards, they are carefully joined together, equipped with connecting elements depending on the model and finally coated or encapsulated.
The manufacturing of PTC thermistors begins with powder making
The raw materials such as barium carbonate and titanium oxide are accurately weighed and proportioned, mixed with deionized water, and ball milled. The materials are mixed evenly through ball milling. Then the powder is dried and spray granulated. Before going to the next step, the appearance, water content, fluidity, density and electrical properties of the PTC thermistor powder should be carefully checked.
PTC Pressing
Put the powder into the tablet press and press it into pills, tablets, sticks, tablets, etc. according to the requirements. And carefully check the appearance, size and weight of the pills.
Sintering workshop
The disc is placed in a crucible and sent to a sintering kiln for firing. After high-temperature sintering, it becomes a semiconductor and forms a resistance value. After sintering, appearance, resistance, and withstand voltage tests are required.
PTC electrode saturation
The bottom ohmic electrode and the surface electrode need to be made through processes such as silver printing, silver baking, and electrode saturation. After the electrode process is completed, the appearance, ohmic contact, solderability, adhesion, etc. need to be inspected.
