Can the Integrated circuit testing products test any defective Integrated circuit?

Thanks & Regards,

The circuitry within a microprocessor is generally microscopic, so the probes of a multimeter tester will not be fine enough to test individual wires. In addition, as per this topic (https://biology-forums.com/index.php?topic=491754.0), integrated circuits contain millions of transistors. In an integrated circuit, these are extremely tiny; however, if a transistor were larger, you could test transistors using these steps:

Step by step instructions:
  • Set the meter to its ohms range - any range should do, but the middle ohms range if several are available is probably best.
  • Connect the cathode terminal of the diode to the terminal marked positive on the multimeter, and the anode to the negative or common terminal.
  • Set the meter to read ohms, and a "lowish" reading should be obtained.
  • Reverse the connections. This time a high resistance reading should be obtained.

I'd say that if the integrated processor fails, it's like due to physical or water damage, and you're better-off replacing it.

Thanks.

As per attached images, the Integrated circuit testing products, will they identify defective Integrated circuits?

Yes, it should output a code to tell you the issue with the chip. Sorry, I thought you were referring to a multimeter :zipper_mouth: Do you know the name of the chip that you need diagnosed?

Thanks.

I mean can those products test any Integrated circuit (chip) which is defective or not ?

Or they have their own limitations.
