Diagnosing Failures Circuit Diagram 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). This tutorial on electronics troubleshooting techniques, you should be able to explain general troubleshooting techniques, major types of circuit failures,

Troubleshooting is the process of isolating and identifying a fault in something so that it can be repaired. There are lots of variables to consider when troubleshooting a faulty electronic circuit. In this article we will look at the techniques I have developed to troubleshoot electronic circuits from over 50 years in the electronics industry. 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.

Practical Troubleshooting of Electronic Circuits for Engineers and ... Circuit Diagram
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. 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

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. Printed circuit boards play huge roles in manufacturing today. Here's what to look for when troubleshooting and maintaining your circuit boards.
