Asking a Vendor for Reliability Data

Selecting as a supplier for components or subsystems involves many aspects, including the desired reliability performance.

Once selected, the ability of the supplier to provide items that meet or exceed the reliability requirements relies on their understanding of the requirements and operational conditions related to the specific item within the system.

It also relies on the supplier’s knowledge of their own design and manufacturing processes as it relates to reliability performance.

Creating Unique Reliability Tests

A common request of reliability professionals is to design a set of reliability tests.

Many rely on standards, such as 85°C / 85%RH, to determine if a system is reliable, yet the standards do not provide a means to translate the results to your specific situation.

Reliability and Tolerance Analysis

A tolerance specification is how we communicate the allowance for part variation.

Variation happens, and when it is within what we expect, great. Otherwise, quality and reliability issues ensue. Let’s explore how to set tolerances to improve reliability properly.

Let’s understand the process data, stability, and design constraints in an attempt to find a balance to create meaningful tolerances.

Getting Started with Reliability Engineering

Every project and program includes reliability engineering.

This may be obvious with a structured program and reliability plan or may be unspoken. The product or system will have some level of reliability performance whether or not anyone is overtly working to achieve a reliability goal.
