Specialized solutions to deal with LED square downlight failure

LED square downlights are in great demand and therefore on the current market situation presents a lot of LED square downlight also on manufacturers, in the factory before it is bound to be useful in detecting, preventing bad light product presentation. Briefly below will teach you how to distinguish Weld death caused by light and LED square downlight solution, I hope everyone can supply assistance.

The problem is relatively simple but very efficacious. LED square downlight failure is due to overheat. We put some unlit LED square downlight LED lead is heated to 200-300 ℃, if the LED lamp can be lit, but followed the lead temperature decreases from light LED square downlight turns off, which confirmed LED square downlight is Weld.

The packaging process is the formation of a certain part of the reason for ignoring this LED square downlight primary reason is to ignore the failure lights formed. If staff are not careful, the silver paste (on the single-chip solder joints) point or points is much less, and are indispensable for much glue will return to the chip gold pad, a short circuit, a little chip is not strong and sticky . Pressure, time, temperature, power must be appropriately four parameters together; otherwise the pressure easily crushed chips, too small to easily soldered.

LED square downlight cone handling electrostatic damage film formation, the LED chips of the PN junction out effect leather and fatal strokes light approach. LED chips of the PN junction out effect leather and strokes are fatal lights greatly staff itself with the task caused, how many body with static electricity, and the differences between people wear fabric clothing, and everyone's physique, dark winter days we undress it is easy to see the clothes discharge between scenes, so the task should wear anti-static clothing, wear a wrist strap, wrist strap should be grounded superior, there is a need grounded antistatic wrist strap result is not good, it is recommended not to use with this kind of items, if the task, in breach of rules, the response should bear warning education, but also play the effect of the notice of others.
