Quality
Strict quality control and various tests in reliability allow us to guarantee the highest quality in our products. All our products are held to our rigorous standards and tested using our vast array of test equipment, including electrical characteristic test machines, thermal shock testers, pressure controlled testers (PCT), high temperature reverse bias (HTRB) testers, x-ray fluoroscopy devices, DE-CAP analysis equipment, thermal resistance junction testers (RTHJ), and the like.
This is to simulate the electrostatic capacity to test the electrostatic shock of diodes for ensuring high quality.
This is to test diodes at high ambient temperature under the regular operation in a long period. The device is to test the noise figure status of diodes during their operation.
Measure thermal resistance, Rth, by delta VF reading among Tj, Ta, Tc, T and derived K instant (℃/W). Dynamic thermal resistance reveal can monitor actual thermal consumption.
This is a reliability test to check if diodes can sustain the transient environmental temperature change from extreme low to high under the condition of regular operation.
This is to test the tensile status of solder lead and die bonding before packaging.
This is to test the quality of diode packages by the condition of constant vapor pressure and humidity.
High humidity & high temperature reverse bias testing is to evaluate the reliability of diodes by measuring and monitoring the states of their leakage currents in high temperature, high humidity and high bias voltage environment.
Simulate the transient wave generated at the moment when the battery being charged leaves the alternator while the alternator is still supplying other loads. (ex: the fuse is blown, the battery is manually disconnected during the repair process).
HAST is based on the environmental parameters of temperature, humidity, and bias, to accelerate the penetration of moisture into the sample in order to evaluate the moisture resistance of the test.
