Many customers now need anti-static trays, but they haven't touched the anti-static trays before. They don't know much about them. So there are a lot of questions about using anti-static injection trays. Here you can read the characteristics of anti-static injection trays.
Why use an antistatic injection tray?
Because electronic products inevitably produce some friction during transportation and packaging, from the physics point of view, friction will of course cause static electricity, and the temperature changes will also generate static electricity. If these static electricity stay in the circuit The board can easily cause a short circuit to damage these delicate electronic products. In order to avoid this, the packaging material requires an anti-static tray.
The so-called anti-static injection molding tray refers to the injection molding package with anti-static function. Compared with the ordinary injection-molded packaging, it has an anti-static performance.
Anti-static principle: the static electricity generated by its own friction is guided away, so that the static electricity does not stay in place to generate voltage.
Anti-static index: usually measured in ten to eight times to ten times as standard
What if the injection tray has anti-static function?
There are two approaches in the plastic packaging industry:
1. After the injection molded product is formed, an antistatic injection tray made of an antistatic liquid is sprayed on the surface of the product to form a conductive layer, and the liquid is dried and adsorbed on the surface;
2. Add anti-static material to the raw material of the blister sheet, which can be carried out at the same time as the raw material is produced;
3. The method of entering anti-static material is higher than the cost of external coating, but its anti-static value is very stable, anti-static effect is permanent, external spraying
The anti-static performance of the method is generally only maintained between March and 1 year, depending on the quality and concentration of the electrostatic liquid and the thickness of the spray.
Where can an anti-static injection tray be used?
Used in the packaging and transportation of precision electronics products, such as LCD screens, precision circuit boards, camera lenses, LED products, etc.
In the end, this problem must be noted. All qualified anti-static products will have product certification and relevant test reports.
