How do you troubleshoot IC?

Check for Short-circuiting

  1. Set the multimeter to its continuity function.
  2. Bridge all the pins on one side of the IC and connect it to one of the multimeter’s test probes.
  3. Test each of the IC pins with the remaining multimeter test probe: if there’s continuity in more than 50% of the pins, then the IC is likely shorted.

How do you check if an IC is working?

In order to test whether or not an IC is in working order, engineers test ICs in 2 levels: wafer level testing and package level testing. There are essentially four general tests one can conduct to check the condition of the IC: shorting condition, leakage condition, supply conditions, and input and output conditions.

How do you troubleshoot a circuit?

Do You Recognize the 8 Techniques to Troubleshoot Your Electronics Circuit?

  1. Confirm the Problem in the Circuit.
  2. Consider Visual Inspection First.
  3. Select Troubleshooting Tools.
  4. Power up the Circuit.
  5. Check the Power Supply Block.
  6. Check the Individual Components.
  7. Check the Main Controller.
  8. Check the Loads by Metered Power Supply.

How a faulty integrated circuit can be tested in an electronic circuit?

If the voltage of the pin of the IC is abnormal, it should start from the maximum deviation from the normal value. And the imported pumps should check whether the external components are faulty. If there is no fault, the IC is likely to be damaged. One is caused by the failure of the integrated circuit itself.

What happens if IC is damaged?

The damaged CPU IC leads to a permanent fault in your phone operating system. Most times, this damage is from a loosened soldered component on the cell phone IC. Flash / Memory: The flash/memory integrated circuit stores app memory on your phone. They are used within circuits to supply data storage to an application.

How do you check if a 555 timer is working?

How to Check the 555 Timer IC? First of all, insert the IC in socket (if used) very carefully so that no pin of 555 timer gets damage. Now to see the result, switch on the power supply. If your 555 timer is working properly, then both the LEDs (Red LEDs in my case) will glow alternately.

What are the basic troubleshooting techniques?


  1. Don’t panic. Relax.
  2. Prepare for the worst — back it up.
  3. Make sure there really is a problem.
  4. Know your computer.
  5. Look for clues and write them down.
  6. Think about what changed recently on your computer.
  7. Determine repeatability.
  8. Reboots can do wonders sometimes.

What are the six steps in the troubleshooting process?

The six steps are:

  1. Identify the problem.
  2. Establish a theory of probable cause.
  3. Test the theory to determine cause.
  4. Establish a plan of action to resolve the problem and implement the solution.
  5. Verify full system functionality and if applicable implement preventative measures.
  6. Document findings, actions, and outcomes.
