Active–Component Full–Life cycle Test Solutions

Changzhou Hopetech Electronic Technology Co., Ltd., founded in 2009, is a national high-tech enterprise integrating R&D, manufacturing, sales and service. We participate in the formulation of national metrology standards and deliver domestic alternatives for multiple imported test instruments.

For active-semiconductor component industries, Hopetech builds a complete test-instrument portfolio covering on-state resistance testing, ultra-low-resistance measurement, high-voltage hipot verification, isolation-insulation testing and mass-production insulation screening. It covers full workflows from incoming IQC inspection, laboratory precision calibration, device high-voltage withstand validation to production-line batch screening. Our solutions satisfy R&D, incoming-inspection and factory-release-test requirements for power semiconductors, discrete devices, optocouplers and integrated circuits. Products are sold worldwide, supporting communication-protocol integration, automated-production-line integration and remote technical support.

HT3545 Fast High–precision DC Resistance Tester: Precision–parameter Calibrator High-accuracy DC-resistance measurement for on-state & pin-resistance calibration of precision semiconductors. Ideal for R&D labs, sample validation and precision incoming inspection.

HT3540A/B Ultra–low Resistance Tester: High–power–device Resistance Detector Micro-ohm-level measurement for ultra-low on-state resistance of high-current power devices. Detects abnormal conduction loss and avoids end-equipment overheating failures.
