Electrostatic does great harm to the LED lights

  Electrostatic is a great harm for LED light, because there are countless electrostatic damage electronic components in the world, resulting in tens of millions of dollars in economic losses. So to prevent electrostatic damage to electronic components is a very important task. LED packaging, application of the enterprise must be taken care. Any problems will cause damage to the LED lighting, the LED lighting performance deterioration even get 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.

 Electrostatic does great harm to the LED lights

  Human electrostatic damage to the LED is great, during working, we should wear anti-static clothing , equipped with electrostatic rings and static ring should be well grounded , there is a need that does not grounded antistatic wrist strap to yield, which is not good, it is recommended not to use the strap the kinds of products, if staff violate rules, they should receive the appropriate warning education , but also play the role of someone else notices the body with a static number , and people wear clothes of different fabrics , and each person's physique , autumn winter night we saw the clothes undress easily between the discharge phenomenon , which had three electrostatic discharge voltage kV .

  Some companies use manual welding, using a 40- watt ordinary soldering iron, soldering temperature can not control. The temperature of the iron is at 300-400 ℃ or more, excessive soldering temperature can also cause dead lights , LED Lead in high temperature coefficient of expansion have several times higher than about 150 ℃ coefficient of expansion , internal gold solder because excessive expansion and contraction will pull welding points , resulting in dead lights phenomenon !
