PolyTerm parts are nickel and tin plated using the same
process as standard parts. There is no effect on solderability
or capability to withstand the soldering process.

PolyTerm capacitors are ideal for use in telecom, power
supply, inverter, and modem applications.

beNdꢀtestꢀdescriPtioN
The test board is designed so that the capacitance of the part can be measured while the part is being flexed
(See figure 1). The capacitor is mounted at the center of the board. The testing equipment has a pressing block
that is located so that it applies force at the center of the test board from below the part at a constant rate. Since
the edges of the board are held in place by the support pins, this causes the board to flex. The amount of flex is
measured in millimeters from the center of the board to the edge, please see “A” in Figure 2.

As the test board is flexed, the capacitance is constantly being measured by a capacitance meter which is con-
nected to the test boards through capacitance probes. The capacitance is first measured at 0mm flex to establish
the nominal value. The test board is then flexed to 1mm and held for at least on second, then the capacitance
is measured, it is then flexed to 2mm, and so on up to 5mm. Any change in capacitance that exceeds 5% of the
nominal value is considered a failure.

Johanson Dielectrics receives a lot of requests from our customers to help them with cracking issues. One cus-
tomer had cracking at a rate of 16% on 1206 size high voltage capacitors during their process. The top picture
of Figure 3 shows a clear mechanical crack with a 45 degree angle at the termination solder pad interface. Re-
®
populating the same board with PolyTerm capacitors showed no cracking failures. The bottom picture of Figure
®
®
3 shows how PolyTerm Capacitors solved these problems. No cracking was exhibited on any of the PolyTerm
capacitors during the customer assembly process.
