The Basics of Signal Integrity Testing

In signal integrity testing, this is generally used for 2-port or N-port S-parameter measurements with a DUT or proposed channel design with the goal of extracting the S-parameters of the transmission line sections/DUT in the channel. S-parameters for transmission lines or DUT can then be compared with simulation results or signaling standards before signoff.

What are MLCC or Multi-Layer Ceramic Capacitors?

Multilayer ceramic capacitors (MLCC) are a type of capacitor that have multiple layers of ceramic material that act as a dielectric. They can also be thought of as consisting of many single-layer capacitors stacked together into a single package. MLCCs have alternating layers of metallic electrodes along with layers of dielectric ceramic. These

What are the test conditions for a capacitor?

The test conditions shall be defined in the detail specification. For all capacitors except those of item b) and c) below: IEC 60068-2-20, Test Tb, method 1 (solder bath). IEC 60068-2-20, Test Tb, method 2 (soldering iron). For surface mount capacitors, IEC 60068-2-58, reflow or solder bath method.

What is the test UC for a capacitor?

The capacitors shall be subjected to IEC 60068-2-21, Test Uc, as applicable. Method A, severity 2 (two successive rotations of 180°) shall be used. This test shall not apply is in the detail specification the terminations are described as rigid and to components with unidirectional terminations designed for printed wiring applications.

What are the recommendations for the capacitor part?

The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.

How long should a capacitor be tested?

At these parameters of the model the acceleration factors are large, and a 96-hour testing of capacitors at 2 times rated voltage (VR) and 125 °C during voltage conditioning (a typical screening procedure) would be equivalent to testing at operating conditions (assumed 50 °C and 0.5 VR) to more than a thousand years of operation (see Figure 1).

Are chip capacitors destined for high reliability testing?

Chip capacitors destined for high reliability testing are often designed with an added margin of safety, namely maximization of the dielectric thickness, and tested extensively for electrical properties prior to burn-in (e.g., capacitance, dissipation factor, and insulation resistance).

What specifications are applicable to burn-in of multilayer ceramic capacitors (MLCCs)?

The specifications applicable to burn-in of multilayer ceramic capacitors (MLCCs) are MIL-C-55681, MIL-C-123 and MIL-C-49467. Burn-in may also be performed to particular customer specifications.
