FAQ

 

Q: How many days is the price valid for?
A: The price is valid for one day due to daily fluctuations in silver price. Please consult the salesperson for the exact price.

Q: How should the conductive paste be stored?
A: a. Short-term storage. Seal and place at room temperature within 3-5 days.
b. For long-term storage, sintering slurry (sintering temperature above 400°C) can be stored at room temperature below 25°C, and stored in a refrigerator when the room temperature is higher than 25°C.
c. Quick-drying slurry and low-temperature curing slurry (below 200°C) can be stored in a refrigerator at 5~15°C.
d. Regardless any type of slurry, remember to seal it during storage.

Q: What are the precautions before using conductive paste?
A: a. Take it out half a day in advance to warm it up or preheat it in a ventilated oven at 25~30°C for 20 minutes.
b. Do not open it before it returns to room temperature to prevent water vapor from cooling into the paste.

Q: What should be paid attention to when using the conductive paste?
A: a. Make sure the paste is consistent with the ambient temperature.
b. Stir it thoroughly before use to restore the performance of the paste.

Q: Do we need to add diluent when using conductive paste?
A: a. Generally, the viscosity of the paste is adjusted before leaving the factory, so it can be used directly after fully stirring without adding diluent.
b. If it is necessary to add due to the process, such as increasing fluidity, spraying process, etc., add small amounts gradually and stir thoroughly. Do not add too much at one time.
c. Please use special diluents and do not mix them to cause performance changes.
