Description: Soldering wires to the electrodes of piezoceramic sheet and/or the center shim of a 2-layer bending element can be difficult if the proper materials are not used. There is a vast array of materials to choose from. The Solder / Flux Kit offers the right materials to get started at once and provides information to procure materials directly from the manufacturer later. Recommended procedure is described.

Nickel Electrodes: Nickel has good corrosion resistance and is a good choice for both DC and low frequency AC applications. It can usually be soldered to easily with tin/lead solder. Electroless nickel, used for plating piezoceramic, contains phosphor. Sometimes the phosphor content in a plating run can make it hard to solder. Vacuum deposited nickel electrodes are usually very thin, making soldering tricky.

Description of Center Shims: Generally, the center shim layer of a 2-layer piezoelectric bending element is either brass or stainless steel. A wire is attached to the center shim if the element is used in parallel operation. Shims are soldered in the same way as electrodes, using the proper liquid flux.
