Specification
|
product: |
Copper paste |
|
Part number: |
25H-1805 |
Application:
This Specification applies to ceramic capacitor conductive paste.
Operating conditions：
|
Substrate |
Ceramic |
|
Printing |
200-300 mesh stainless screen |
|
Levelling |
5-15min minutes at room temperature
|
|
Drying |
Place in a ventilated oven and bake at 100-150℃ for 10-15 minutes. (The baking temperature is below 300℃. The baking time can be determined according to the actual situation of the baking process.) |
|
Firing Condition |
The sintering process is carried out under nitrogen protection atmosphere in the tunnel furnace, with a peak temperature of 830 ± 10℃ (recommended value), for 10 - 20 minutes. (As per actual requirements, the sintering range can be adjusted within 800-850℃, but the peak temperature duration must be at least 10 minutes.) Generally speaking, the performance of ceramic capacitors after high-temperature sintering is superior to that after low-temperature sintering. |
