- 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
