- Paste Type: Conductor
- Application Method: Screen Printing
- Substrate: PZT, Alumina, Other Functional Ceramic
- Metal: Ag
- Application: Component Metallization
- Description: 3255 is a silver conductor paste designed to screen print solderable electrodes onto a variety of electrical ceramic component devices. The fired film forms a highly adherent bond to many types of substrates, including piezoelectric transducers (PZTs), NTC thermistors, alumina, steatite and porcelain. The metalized electrode is solderable for external lead attachments.
- Key features: Excellent adhesion#Excellent solderability#Compatible on piezoelectric transducers (PZTs), NTC thermistors, alumina, steatite and porcelain
- Process Temperature: 725-850 ºC peak temperature. Dwell time 8-12 minutes at peak. Cycle time of 45-60 minutes. Larger parts may require a longer firing profile.
- Film Thickness : 8-14 um
- Viscosity: 110-130 kcps Brookfield RVT spindle #7, at 20 rpm, 25 °C
- Conductivity: ≤ 3.0 milliohms/square at 25 um fired film thickness
- Alloy Ratio: 100
