Definite analysis for LED CHIP leakage.
LED chip leakage problem has been encountered by many users. The timing of led chips leakage is different, some defective led chips are found after led packages were soldered, some defective led chips are found during production testing, some defective led chips are found after the LED package is completed, some defective led chips are found during using, some defective led chips are appearing in the warehouse, and some defective led chips are found after 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.
