How to choose the material of the pc endurance board? What are the differences between the materials? Let's take a closer look. The PC endurance board is divided into several grades according to the quality. First of all, customers should understand. Generally can be divided into high, medium and general three grades. In order to adapt to different customer groups and customer needs, the product is divided into three grades according to quality assurance, 10 years warranty, 7 years warranty, 5 years warranty, 3 years warranty.
The brand, raw material, quality and price of each product are different. In addition, some manufacturers provide low-end PC endurance boards. When the market price of pc endurance board is shaken, customers can only choose according to the purpose and needs of their products.
Below I will introduce some methods that distinguish the good or bad of the PC endurance board:
1. Use your hand to pinch the pc endurance board. Then the specific gravity of the pc endurance board is sufficient, and the strength is naturally good. On the contrary, it is lighter and less powerful. Keep the film clean and tidy.
2. Observe the pc endurance board packaging. Clean, with or without falling off, these details can show whether the manufacturer pays attention to the production process. Here is mainly to reflect the attitude, observe whether the color of the pc endurance board is uniform.
3. Peel the maintenance film. Whether the pc endurance board is flat, there are bubbles and particles. If the particles and bubbles are larger, the raw materials of the pc endurance board are poor, and the low-grade board is used. If it is smaller, it may be a better raw material. If there is almost nothing, it means that it is a good quality raw material. This is usually the case for plates that have been guaranteed for ten years.
According to the above method, the PCB endurance board can be selected to be better. As the saying goes, one penny is worth the price. In the face of the product with too low price, the customer should pay more attention when purchasing. Meet the required quality specifications. At the same time, we must also pay attention to some merchants shoddy, whether it took 10 years warranty money to buy products with 7 years or 5 years or even lower warranty.
