How prevention LED die light ?
Electrostatic LED light is a kind of great harm of the devil, because the world countless electrostatic damage electronic components , resulting in tens of millions of dollars in economic losses . So to prevent electrostatic damage to electronic components , the electronics industry is a very important task , LED packaging , application of the enterprise must not be taken lightly. A part of any problem , will cause damage to the LED , the LED performance deterioration or even failure .
We know that the body (ESD) Static electricity can reach about three volts , enough to damage the LED chip breakdown in LED packaging production lines, various types of equipment grounding resistance meets the requirements, it is also very important, and generally require grounding resistance of 4 ohm , some demanding applications or even to reach the grounding resistance ≤ 2 ohms.
Human electrostatic damage to the LED is great, the work should wear anti-static clothing , equipped with electrostatic rings and static ring should be well grounded , there is a need not grounded antistatic wrist strap to yield good results , it is recommended not to use the strap the kinds of products, if staff violate rules, should receive the appropriate warning education , but also play the role of someone else notices . How much of the human body with static electricity , and people wear clothes of different fabrics , and each person's physique , autumn and winter, the night we saw the clothes undress easily between the discharge phenomenon , which had three electrostatic discharge voltage kV .
