Traffic signal: the anti - static process of the signal lamp manufacturer

    For the block, I think a lot of industries can come to the anti - static process of our factory.

    When the electrostatic discharge damage to the signal lamp comprises a circuit board and some of the original instigator of the gladne let us the signal lamp manufacturers feel a headache, a lot of people think they are working under the environment of electrostatic discharge, but ESD or every year to the global bring billions of dollars in losses. In particular, photovoltaic and photovoltaic as well as the lighting industry, so for our signal lamp manufacturers, the prevention of static electricity is a very important process.

    Before we signal lamp manufacturers for the treatment of electrostatic is generally the following two: small static electricity grounding, electrostatic big buy special electrostatic eliminator. But these two methods do not have much to do with the effect of preventing static electricity. In the street lamp industry. LED lamps are most afraid of static LED, most afraid of static electricity, outdoor large screen to install lightning protection facilities, indoor should strengthen attention.

    In order to imitate the electrostatic film that may be subjected to in the real environment, the international standards committee has formulated the relevant standards, and the national or regional national or Regional Council will adopt these standards as national or local standards. In particular, the European market for electronic appliances to enter the EU products must be in conformity with the EM (2004/108/EC) requirements, electrostatic discharge is one of the EM (test). Our signal lamp manufacturers are also in the production of electronic products, so we should also EM requirements.

    We know that the electrostatic discharge is caused by the charge of the movement. So we can consider two main method of signal lamp manufacturers, one is to prevent the circuit discharge, two is the fast charge of the charge, of course, the charge of the channel is also generated by the discharge, the electric field on the electric circuit is also to be considered.

The following three principles must be followed in the production of LED:

    Assembly bench (table) is to be used for anti - static pad, and grounding. LED packaging bag packaging materials and semi-finished products to use anti-static sponge or packaging

    LED the use of anti - static element box. Operator wearing the electrostatic ring if there is lead out, also need to put the lead wire on the ground. Semi manufactured goods and finished product testing equipment are also required to meet the ground.

The iron, cutting machine, tin (or automatic reflow equipment) required grounding.

    But these are just some palliative way, because the encapsulation of LED chip antistatic ability and the strength of the LED lamp has nothing to do, but depends on the LED chip itself. LED lighting equipment manufacturers should use the high resistance of the LED chip, because the high resistance of the LED chip to adapt to a variety of environments, which will be able to completely solve the problem of static electricity caused by leakage of LED lights, dead lights and other quality accidents.
