External Termination

Standard MLCCs are prone to cracking due to mishandling,

depanelization, and board fleꢁing. In response to customer

requests for higher resistance to mechanical stress, and as

a result of continuous efforts to improve our products, JDI

has introduced PolyTerm termination ceramic capacitors

to meet those customer requirements for increased

resistance to fleꢁure cracking.

PolyTerm is a conductive epoꢁy termination material

loaded with silver, allowing it to absorb much more bending

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.

Units: mm

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.
