Free Electronics Design Reliability Calculators

Here’s a useful collection of online tools for determining various reliability metrics for electronic components, circuit boards, and complete assemblies, including:

Capacitor Flex Cracking — Allows the user to predict the probability of flex cracking in chip capacitors and to see how adjusting certain design parameters will allow the user to avoid this type of failure.

Solder Joint Fatigue— Predicts the lifetime of leadless chip components (LCCs) as a function of solder material, component type, PCB properties, and use environment.

Plated Through Hole (PTH) Fatigue — Computes the mean fatigue life for printed circuit board materials based on the type and thickness of the material, PTH size, and thermal environment.

Component Vibration Fatigue — Computes the cycles to failure for various component types based on the expected vibration environment, as well as the given component and PCB characteristics.

Intermetallic Growth Due to Thermal Aging — Computes the thickness of an Intermetallic Compound (IMC) given the average operating temperature and time period of operation.

Thermal Cycling to Service Life Correlation — Correlates thermal test results with expected field results, and vice versa.

Unit Conversion — Converts values from one unit of measurement to another, including length, area, temperature, time period, and force.
