Questions and General feedback Circuit Diagram Printed circuit boards play huge roles in manufacturing today. Here's what to look for when troubleshooting and maintaining your circuit boards. An intermittent fault, often called simply an "intermittent" [citation needed] (or anecdotally "interfailing" [citation needed]), is a malfunction of a device or system that occurs at intervals, usually irregular, in a device or system that functions normally at other times. This tutorial on electronics troubleshooting techniques, you should be able to explain general troubleshooting techniques, major types of circuit failures,
An open circuit failure caused by inner-layer separation can cause intermittent electrical open or complete open after the board undergoes thermal processes (reflow, wave soldering, or rework).

When an IC fails--or we think it did--efficient failure analysis and troubleshooting requires information. This tutorial describes how to efficiently research the issues. Singh et al has used the fault tree method for intermittent faults diagnosis for electronic control unit (ECUs) and sensors for vehicles and built a data-base of signals to describe the possibilities for intermittent failure.
This paper reviews the possible causes and effects for no-fault-found observations and intermittent failures in electronic products and summarizes them into cause and effect diagrams. Several types of intermittent hardware failures of electronic assemblies are investigated, and their characteristics and mechanisms are explored. One solder joint intermittent failure case study is presented. The The problem could lie in the controls hardware, it could be caused by wiring faults, it could be introduced by a recent software update - the possible sources are endless but downtime costs money, so that support team needs to isolate and fix the problem as soon as possible. | Industry Insights | Troubleshooting Tips: Isolating Intermittent Faults
