1. Avoid contact with weak acids
Weak acid substances generally do not cause corrosion to articles. However, due to the different chemical structures of PCB boards, it is necessary to avoid contact with acid substances. Even weak acid substances should try to avoid corrosion to veneers.
2. Do not touch sand ash
PCB board can not contact sand ash wood, because the surface of aluminum products has a layer of natural aluminum element protective film, which is a natural barrier against oxidation and one of the anti-corrosion structures. If the PCB board is in contact with them for a long time, the protective film will be broken and damaged, which will affect its anti-oxidation effect. If there is dust on the surface of the PCB board, it can be wiped with linen or cleaned with rubber products.
3. Avoid direct sunlight
PCB board should also avoid regular contact with ultraviolet ray in daily life. Any aluminum product that is often in contact with ultraviolet ray will cause its surface to be oxidized, accelerate the oxidation rate, and make it lose luster. Therefore, it is necessary to avoid direct sunlight.
4. Do not strike excessively
Although the PCB board has a certain bearing capacity and has a certain hardness and compression resistance after alloy injection, it can be seen from the characteristics of its raw materials that aluminum is not a natural pressure resistant material, so its pressure resistance is slightly weak compared with other metals. Therefore, try not to make it have too large impact to prevent fracture in daily use.
The above are the main points that PCB manufacturers should pay attention to when introducing PCB boards in daily use. In daily use, try not to use your hands frequently to prevent the stains on your hands from condensing into blocks after contaminating the layout, and also prevent the chemicals on your hands from affecting it. At the same time, do not keep it in a humid environment for a long time to avoid damaging the structure. Enterprises must examine the overall strength of the manufacturer when mass customization.
