Online TCR testing equipment

This device can measure the temperature drift value of chip resistors by measuring their resistance values at room temperature and high temperature. By using a standard turret platform combined with a mature discrete component testing system, it can meet the detection needs of different customers for the temperature drift value of chip resistors.

Thick film resistor, thin film resistor, thermistor

Heating and constant temperature system
The heating and constant temperature system adopts multiple temperature sensors to monitor and dynamically adjust the temperature of the chamber in real time. When the temperature changes slightly, it can also receive feedback in a timely manner to ensure that the temperature change is ≤± 5 ℃.

Mature electrical measurement scheme
By using Kelvin (four wire system) testing method and effective shielding against interference, the repeatability deviation of resistance values between the external and internal electrical measurement stations at room temperature can reach ± 0.01%, and the repeatability of resistance TCR can reach ± 1ppm/℃.

Online measurement
The equipment can automatically perform functions such as feeding, appearance inspection, room temperature resistance measurement, product heating, high temperature resistance measurement, graded feeding, and nozzle cooling.

high-precision
Adopting high-precision module design combined with Japanese imported DD motor to ensure stability, motion control fully servo motor drive, positioning accuracy can reach 0.01mm
