Material Notes:
This conductor composition is a silver bearing paste composition designed for screen print application of a solderable electrode base onto various types of electrical ceramic component devices. The fired film forms a highly adherent bond to many types of substrates such as piezoelectric transducers (PZTs), NTC thermistors, alumina, steatite and porcelain without altering the electrical and mechanical properties of the dielectric body. The bonded electrode is readily solderable for external lead attachments.All information provided by Lord.
