According to the statistics, when the LEDs on the LED display not work well, for 50% the problem happens because of soldering problem. Usually we call this kind problems as "pseudo Soldering", "cold joint", "inveracious Soldering", or "spurious joint".
This is the "headache" of many led display manufacturers, and many clients complain on this. The soldering problem happens on the LED leadframe, IC leadframe, PINs etc. If there is only one component has the soldering problem, it would be not such a big case because you could just simply re-solder that component to solve this problem. And in quite a lot of cases, you just punch the led display panel, the screen may possible work again in normal status.
But if the soldering problem is caused by the led display production technology itself, it would be very serious. Imagine when on the led screen, sometimes the LEDs die on one part and sometimes die on another part, it would be really awful as it's impossible to replace all the components.
Moreover, it is very hard to find out all the "hidden" problem of the soldering.
Some the manufacturers believe this problem could be eliminated with the vibration test before the consignment. It is a helpful method to test but not a helpful method to avoid the soldering problem from the root.
To solve the soldering problem completely, there's no way but to pay more attention to the production technology. When jointing the components, the jointing material should be very well selected, the equipments should be configured with a reasonable parameters, and the workers should be well educated and skilled.
