DESCRIPTION OF ELECTRODES
Piezoceramic electrodes will be either fired silver or nick-
el. Silver electrodes are flat white in color while nickel
electrodes are grey.
DESCRIPTION OF CENTER SHIMS
Generally, the center shim layer of a 2-Layer piezoelec-
tric 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 the nickel electrode. The proper liquid flux
choice must be made depending on the shim material.

ORDERING INFORMATION
PART NO.
1 pc.
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 materials to choose from. The solder & flux kit
offers the right materials to get started at once and pro-
vides information to procure materials directly from the
manufacturer later.
Recommended procedure is
described. Materials in the kit are for soldering to nickel
electrodes unless specifically requested for silver.
Silver electrodes are not recommended for high electric
field DC applications where the silver is likely to migrate
and bridge the two electrodes. It is often used in non-
magnetic and AC applications. Silver used as an electrode
is in the form of flakes suspended in a glass frit. It is gen-
erally screened onto the ceramic and fired. The glass
makes the bond between the ceramic and the silver par-
ticles. Silver is soluble in tin and a silver loaded solder
should be used to prevent scavenging of silver in the elec-
trode.
Nickel has good corrosion resistance and is a good choice
for both AC and DC applications. It can usually be sol-
dered 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 elec-
trodes are usually very thin,making soldering tricky.
Choice of the correct flux (to remove surface oxidation)
generally makes soldering to electrode surfaces easy even
under adverse conditions.
