As we know that the problem of LED CHIP leakage has been encountered by many users. Some defectives of led chips are found during production testing, and some defectives of led chips are found during customers use it. The timing of led chips leakage is also different, some defectives of led chips are appearing after a period of time in the warehouse, some defectives of led chips were found after the LED package is completed; some defectives of led chips were found after led packages were soldered; some defectives of led chips are found after the customers has been using it for a while. The specific cause of led chips leakage problem has been plaguing the engineers of the led packaging factories.
LED leakage causes
The reasons for LED chip leakage caused by users are listed. According to experience in dealing with LED chip problems and using LED chips. At present, the main reasons for the most likely LED chips leakage problems are as follows:
(1) The led chips are contaminated (-most important, high-incidence problem)
(2) Temperature of glue is too high.
(3) Wire welding
(4) External stress
(5) Improper using
(6) The chips leak itself
(7) Improper production process, causing led chip cracking
(8) Static electricity
(9) Other reasons
I almost put the problem of static electricity to the end, almost subverting the understanding of the industry and even experts. Why do you put the static problem at the end, and then talk about the detailed reasons later.
