The last article explained the detection process of the full-color led display production process, only half of it, now let's talk about the lower part of the full-color led display detection process:

12, dust-proof experiment: dust-proof IP level explanation

13, welding production line: welding is divided into three types: wave soldering, reflow soldering, manual soldering. This picture is hand soldered.

14. Programmable salt spray experiment:

The programmable salt spray test uses salt spray corrosion to detect the reliability of the sample to be tested. Salt spray refers to the dispersion system consisting of tiny droplets of salt in the atmosphere. It is one of the three series of artificial environment. Many enterprise products need to simulate the damage caused by the climate around the ocean, so the salt spray test box should be shipped. The salt spray test chamber is divided into two types: neutral salt spray and acid salt spray. The difference is that the standard is different from the test method. It is also known as “NSS” and “CASS” test. It is the most common type of artificial weather protection. Test Methods.

15. Waterproof experiment: Outdoor full-color LED display will be exposed to the environment such as rain, especially the outdoor full-color LED display is in the outdoor environment for a long time. Therefore, waterproof testing must be done before shipment.

16. Vibration experiment: anti-vibration and shaking experiment.

17, multi-axis automatic locking screw machine:

In the process of making the LED display, there are many screws that need to be locked. One P16 board needs to lock 30 screws, and the P10 board 20 pieces. Therefore, in the larger LED display enterprises, most of them will have a whole line of special screws. More than a dozen people, specializing in screwing.
