Share how to prove the anti-static performance of anti-static cap
The anti-static cap can prevent static electricity accumulation on the cap through the corona discharge of the conductive fiber, has static elimination, and has excellent ESD electrostatic discharge and dustproof performance. Then anti-static performance is its main performance, and share with you how to prove its anti-static performance, the test method is as follows:
When measuring the performance of the anti-static cap, place the anti-static cap in a temperature of 20 °C ± 2 °C, relative humidity of 50% ± 5%, after not less than 24h, apply in parallel with the flat part of the anti-static cap. Two electrodes, the spacing is 10mm ± 0.5mm, the electrode and the anti-static cap are bonded with a conductive adhesive with a resistance value <1KΩ; the measuring end of the high resistance meter is connected to the electrode, and the resistance value displayed by the high resistance meter is read; The exchange electrode is repeatedly measured once, and the displayed value is recorded; the average of the two measurement readings is the actually measured surface resistivity.
When measuring the antistatic performance of the antistatic cap, it is necessary to have constant temperature and humidity in the room. Apply two electrodes in parallel on the flat part of the tested ESD cap: electrode length: 100mm±1mm Electrode width: 1mm±0.1mm Pitch 10mm±0.5mm Electrode should be placed in parallel with electrode material as metal foil, electrode and anti-static The caps are bonded with a conductive paste with a resistance <1KΩ. Before the test, the anti-static cap should be pre-processed for not less than 24h. Pretreatment method: temperature adjustment and humidity adjustment.
Connect the measurement of the high resistance meter to the electrode and read the resistance value displayed by the high resistance meter. The exchange electrode is measured once. The display shows the value; the average of the two measurement readings is the actual measured surface resistivity.
