The anti-static shielding bag can protect the static sensitive components from potential electrostatic hazards to the greatest extent. Their unique Faraday cage structure forms the induction cover effect and achieves shielding and anti-static effect on the contents of the bag. The following contents are customer defense. Frequently asked questions about the detection of electrostatic properties:
Question 1: If the side of the anti-static bag is cut off by heat sealing or bilateral, what will happen to the measurement?
The test chart is designed to detect the shielding effect of the bag, rather than the metallized film material used to make the bag. If you cut off the heat seal of the bag, you are no longer measuring the bag, but the material.
Question 3: What causes the shielding effect of the metalized anti-static bag to be poor?
There are many reasons. For example, the anti-static shielding bag is excessively wrinkled or damaged, the sealing edge of the bag is not strict, the metal film layer is too thin, and the like.
Question 3: When the discharge simulator releases a 1000 volt HBM voltage, if the anti-static shielding bag is well shielded (internal voltage is less than 10 volts), the power LED is on, but there is no reading on the sensor, then what? Know that this bag has been tested?
The relay inside the discharge simulator will give a slight “click” sound, or the bag will move slightly when voltage is applied, but in order to verify that the discharge simulator and sensor are normal, the sensor should be removed from the bag. On the reference plate, place the discharge head on the upper disc of the sensor and discharge it directly. The reading should exceed 300 volts.
