TCR High-Temperature Tester

TCR High-Temperature Tester

Supplier
Jptoe
Category
Measurement Devices
Origin
China

The high-temperature tester, also called a TCR tester, uses 2T or 4T probes to measure resistance at room temperature, heats the substrate on its platform to a setpoint such as 125℃, and remeasures at high temperature. Resistance changes and temperature difference determine temperature coefficient of resistance(TCR). It also laser-cuts resistors found abnormal before or after heating. A key chip-resistor production system, it measures each resistor's TCR on an individual substrate. Resistor sizes:01005-2512. Resistance range:100-20MΩ.

Key Features

Proprietary lasers: JPT designs cost-effective, long-life lasers with assured service, customizable to applications; optimal fibers, crystals and pumps are assembled and undergo 72H aging tests for reliable long-term use. Accurate, controllable heating: settable temperatures from ambient to 150℃, with small differences between platform edges and center, reaching <±1.5℃. Laser cutting of abnormal resistors before/after heating prevents heating abnormalities or transfer into subsequent processes.
