Electronic measurement instrument waterproof level reflects the instrument waterproof and moistureproof ability, especially for the outdoor activities, be in high humidity or dust in the bad environment, fan ability of sealing and waterproofing for the safe operation of the instrument and it is crucial. Therefore: formulate IEC529 international standards, in order to adapt to the, Japan's technology standard in the protection of the electronic instrument is divided into ten levels
vacuum coating waterproof function of cooling fans
* 1. The temperature range: applicable to - 200 ℃ to + 200 ℃ environment temperature.
* 2. Stress free surface: the circuit sensitivity is not affected.
* 3. The ultrathin membrane layer: the level of surface heat dissipation effect is the lowest.
* 4. The low friction coefficient, the formation of a surface dry film type lubrication effect.
* 5. Organic compatibility: no biological rejection forms like now.
* 6. Transparent: membrane layer of optical quality.
* 7. Excellent cladding is: to improve the positioning of electronic parts and mechanical devices.
* 8. Solvent corrosion resistance: no dissolved in solvent, can be resistant to acid, alkali liquid corrosion.
* 9. High block: oxygen, water vapour permeability is extremely low, at the same time to prevent the free.
* 10. Insulation: can tolerate 3000 v/AC high voltage.
