APPLICATIONS
Used for metallizing ceramics VK-94-1 or VK-94-2 by screen printing followed by firing. See also paste PP-17. Pastes PPS-N1, PP-20-2 (silver-platinum) are used for metallizing the ends of chip resistors by dipping. The conductive film PPS-N1 is resistant to the process of galvanic deposition of a nickel layer.
Paste PPS-N1 is compatible with conductive pastes of the PP series and with paste PPS-2.
The new paste PPS-2-2 with high conductivity is intended for microwave applications.
