Several LED chip leakage reasons

I believe that LED leakage, many manufacturers are inevitable problems. They are everywhere, sometimes in the production process was found, and sometimes have to wait until the customer to buy home only to find. Leakage of the situation after another, and the specific causes of leakage problems, the manufacturer's engineers are helpless
Analysis of the reasons for a few LED leakage,
According to the company for many years to deal with LED problems and the use of LED experience, the company believes that the main reason for the occurrence of leakage of these.
(1) the LED chip in the production process is damaged, which is the most important and often do
(2) silver glue is too high
(3) when the line welding partial welding
(4) the use of the place is not appropriate
(5) the chip itself leakage
(6) production technology does not work, so that the chip cracks
(7) electrostatic effects
If there is leakage situation, then we should pay attention to the power to constant flow, because Led material determines the size of the LED lighting by the size of the environment, such as the higher the temperature, voltage, current increases the greater. Long over the rated current work, will greatly shorten the LED lamp life. The LED constant current is in the temperature and voltage and other environmental factors change, to ensure that its working current value unchanged.
Power supply heat should be noted: the general use of aluminum alloy material, easier to heat. That is why a lot of LED lights are on the aluminum plate in the work of the reasons.
