The operation steps of an integrating sphere spectrophotometer system

As an emerging light source, LED is very different in its own structure and luminous characteristics compared with traditional light sources. Due to the self-absorption effect of the LED itself and the measurement error caused by the inner shield of the integrating sphere, the traditional integrating sphere luminous flux measurement device is used to measure the luminous flux of the LED. The posit...

The Glow Wire test measures ignition resistance of the plastic connector material

The glow wire test is a physical experiment. The purpose is to test the stability of electronic and electrical products at work. The glow-wire tester heats the heating wire of the specified material (¢4 Ni80/Cr20) and shape with a large current to the test temperature (550 ℃ ~ 960 ℃) for 1min, and then burns the test sample vertically with the specified pressure (1.0N) for 30s. Determine the...

IK code: Impact protection in line with the IEC62262 standard

IK ratings are defined as IKXX, where “XX“ is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against external mechanical impacts. The different IK ratings relate to the ability of an enclosure to resist impact energy levels measured in joules (J). IEC62262 specifies how the enclosure must be mounted for testing, the atmospheric con...

Countermeasures and Corrective Measures for Common Problems for EFT Immunity Measurement

1. The mechanism of EFT Immunity Measurement and its impact on electronic products The EFT immunity tester is a transient disturbance generated at the disconnection due to the insulation breakdown of the switch contact gap or the contact bounce when the inductive load (such as relay, contactor, etc.) is disconnected. When the inductive load is repeatedly switched on and off for many times, the pul...
