  • Using Manual Of For High-Frequency Filter Dip Coating SF3400

    1. It is recommended to control the ambient temperature at 20~25℃ and humidity at 50~60% during use;

    2. Use the silver paste within 24 hours after opening. The unused silver paste must not be left open, and the inner and outer covers should be covered and sealed. Storage;

    3. Recycle the silver paste to adjust the viscosity, and a special thinner is required;

    4. When the silver paste is taken out of the refrigerated state for use, please first put the silver paste at the operating temperature (generally 20℃~25℃). Balance, balance time ≥ 4h, special attention: Do not open the silver paste packaging cover during the balancing process, and keep the silver paste packaging tank in a sealed state. After the temperature is balanced, please open the lid and stir evenly;

    5. The working environment should not contain corrosive gases such as sulfide and chloride;

    6. The operator must wear masks, hats, gloves, etc., and do not use sulfide The labor protection supplies;

    7. If it touches the skin, it should be washed with water and soap in time
