World Factory Network is a comprehensive e-commerce service platform for enterprises, committed to providing high standard online ecological construction services. Some practical suggestions for foreign trade newcomers in Electronic Manufacturing Services.
The following are the advantages of the Gufeng queue: 1) When conducting interviews with clients, it is necessary to apply for a company online or apply for a company position on the website. If many programs are applied for online and a company position cannot be found, the postal code will not be able to find all the positions.

Advantages of LED large screen: Strong light irradiation only takes 2 hours and 2 minutes to solve non luminous problems.
We provide prototype display and high-definition viewing evaluation of foldable LED display screens for the design and development version. We also provide tips on screen quality requirements and brand new LED engineering cases.
More environmentally friendly! It only takes a few minutes to solve the non luminous problem, which is an upgrade and renovation of a conventional factory. And the LED display screen driver has been installed, which usually only takes a few seconds to solve the problem of screen damage.
Today we will tell you their working principle, which is a very formal case of LED large screen engineering. Compared to the LED screen engineering solution, the true LED energy-saving light engineering solution can achieve energy-saving for ordinary merchants to pay full screen, while also displaying their own power consumption as much as possible.
From the discovery of LED faults to the direct use of LED lights to convert physical current into LED current, the gate resistance is controlled through heat exchange between the positive electrode material, gate, and heat sink (components), making it conductive. From the characterization of the cause of device failure, if the LED operates in a low state, it generates a large amount of heat, causing an increase in heat. It generates high current and may cause damage to the heat sink. If the LED operates in a high state, the temperature of the heat sink exceeds the insulation of the heat sink, and a malfunction will occur.
Therefore, even if the working state of LED is high, the cooler may still be the cause of constant current device failure. If the LED brightness is higher than the normal working state, causing an increase in heat, the heat dissipation system of the heat sink will be damaged.
Unless the working situation is high, the insulation of the heat sink is not the cause of constant current device failure. LED often does not light up, and there are generally two situations: one is the start part and the LED is commonly referred to as the non start area. There are usually two types of serious faults: firstly, there is an abnormality in the high-voltage drive circuit; The second is a short circuit in the starting circuit; Thirdly, there is an abnormality in the high-temperature drive circuit.
Normally closed system Normally open system Normally closed system Normally open, Normally closed, Open circuit. A common fault is that the IC is interrupted when the LED street light is on, or the IC does not input in a timely manner when the IC1 street light is on.
Its biggest feature is that there is a malfunction in the control circuit, and the IC does not output voltage when the IC1 street light is turned on.
