Entering the aging room, 50 bar counter screens display machines undergoing 72 hours of uninterrupted baking.
The temperature here is set to 45 ℃ and the humidity is 65%, simulating the extreme working environment of a London bar.
Test engineer Xiao Zhang records the data of the LED bar screen display machine every 2 hours: "We use a 'step load test LED bar screen display machine', running at 50% power for 12 hours, then running at full load for 48 hours, and finally conducting voltage surge testing for the last 12 hours. "
He pointed to the curve chart on the wall and said, 'Look at this brightness attenuation curve, it still remains above 97% of the initial value after 48 hours.'
The UL certified product label has been attached to the back of the LED bar display machine screen, and scanning the QR code can view the complete test report.
Humanistic Feature: RuiGuan Electronic LED Bar Screen Showcases the Craftsmanship Spirit of Customized Machine Production
At the optical inspection station, 35 year old engineer Mr. Zhang is using a 40x magnifying glass to inspect solder joints. He is wearing customized LED lighting glasses and gently pinching the probe with his fingers to move the pins.
The defect rate of this batch of LED bar screen display machine orders must be controlled below 0.3 ‰, "he pointed to a module that had just been tested." You can see that the wetting angle of this solder joint is exactly 38 degrees, which perfectly meets the IPC-A-610G standard. "
As he spoke, he took out a clean cloth from the drawer and wiped the lenses. "
These glasses were picked by Xiaolin for me, and he said they are 30% brighter than my original one."
Master Zhang's nails had slight indentations on the edges, which were a medal left by ten years of testing work. Next to the workstation, 80s technician Xiao Chu is using VR glasses to simulate an LED bar screen to display the installation scene of the machine. The figures of two generations of craftsmen overlap under the workshop lighting.
Customer Value: RuiGuan Electronics LED Bar Screen Display Machine Lights Up North American Night Economy
This batch of Rui Guan electronic LED bar screen display machines with P2.5 micro spacing have a resolution of 1920 × 1080 and support HDR10 display.
The customer requires no ghosting when playing sports events, and we have increased the refresh rate to 3840Hz, "the project manager showed the test video."
The multilingual display system can switch between English, Spanish, and Chinese in real time, meeting the needs of international bar LED bar display machines.
The power system certified by UL can adapt to a wide voltage range of 100-240V, and the built-in anti burn mechanism can automatically eliminate the static image residual of the LED bar screen display machine.
At 5pm, the last Rui Guan electronic LED bar screen display machine passed the final inspection and will soon be packed into export packaging with the Ruiguan logo printed on it.
This batch of customized LED display products, which embodies the hard work of more than 20 employees, will become the visual focus of London's nightlife across the ocean.
On the electronic bulletin board in the workshop, the words "Direct Pass Rate 99.7%" are updated in real time.
Behind this string of numbers is China's precise response to European standards and the best footnote to Huabangying's commitment to "not selling defective products".
