Quality Insurance
The factory of PLED has the advanced and precise apparatus & equipments to ensure the excellent quality of the products. Through many years development, PLED has kept a leading position domestically, in the aspects such as on-the-spot management, quality control, technical development mechanism, and management audit and personnel appraisal system etc. in the LED display industry.
PLED has the advanced SMT equipments such as SMT placement machine, reflow soldering oven and wave soldering machine. Also we are equipment with some reliability testing machines such as high temperature aging chamber and temperature shock machine, the automatic machine has been adopted for the dice-bonding wire-bonding, encapsulation and the sorting of brightness and color of the LED elements, In order to increase the stability of the products, we have also got the vibration tester, cold & hot shock testing machine, and testing machine for high voltage, insulation resistance, etc., which have ensured both the complete LED display and components in the stability status.
In order to avoid the potential defects existed in the design and production, we conduct a series of reliability tests such as electronic performance test for semi-finished products and finished products, the waterproof test, the anticorrosion test(salt spray test), the vibration test and temperature shock tester.
1, The reliability Test of the semi-finished products. Before glue-sealing for modules and after QC inspection, more than 48 hours aging should be made in the high temperature for all of the products.
2, Test for finished products. Assembling the finished modules to the LED cabinets and simulates the on site installation. We keep them aging for more than 72 hours, the delivery can be made if only no defects found.
3, Waterproof Test. During the rainy seasons, the performance of the outdoor display is critical. PLED performs the high-pressure water-spraying test as well as submerging test, water-showering test against the front panel to ensure its waterproof. Therefore, the waterproof degree of IP65 has been completely reached.
4, Anticorrosion Test. In order to ensure the reliability of anticorrosion of the PCBs and the cabinets treated by anticorrosion, hence, the salty steam test must be made during the production.
5, Vibration Test: Due to the traffic signal display and the vehicle-carried, ship-carried display working under the circumstances of vibration, in order to ensure its reliability, therefore, the simulated vibration test must be made. For overseas customer, we provide the flight case packing as the option.
The test is approached to the outdoor environment test; it ensures the products will be qualified.
