Failures can be caused by overheating, overcurrent combined with voltage, ionizing radiation, mechanical shock, shock or shock, and many other triggers. For semiconductor devices, problems in the main device case can lead to failures due to contamination, mechanical stress on some devices, or open or open circuits.

Of course, embedded circuits can fail, which can lead to a malfunction. This article discusses some causes of circuit failure, integrated methods and how to fix them. Failure

Causing

The integrated circuits you pay for fail for several reasons. The most common causes of IC failures include manufacturing defects, physical damage to some packaging, harsh environments, and electrostatic discharge (ESD).

The next few sections contain much more information about each of these issues:

Mistakes due to manufacturing defects

Impurities and Impurities The impurities present in bulk silicon, crystal defects and structural elements during the fabrication of an integrated circuit contribute to the stability of the final chip. Small gaps between the chips and (i.e. the substrate, chip clamping error) can reduce the chip’s thermal conductivity.

This problem can result in the inability to overheat with conventional surgical treatment, resulting in premature failure. In addition, tiny cracks at the interface between the chip and the connecting wire due to excessive pressure (i.e. connection pressure, i.e. wire connection failure) can affect the reliability of integrated circuits. Because of

Damaged packaging

Cracks and chips on some printed circuit boards (due to high mechanical or possibly even process temperatures, etc.), which can compromise the reliability of the integrated circuit and lead to interoperationm crashes. At the same time, moisture, and therefore cleaning agents, soaked into cracks can lead to short circuits of internal components and malfunctions; In addition, the packaging of the IC may be damaged during transportation or mishandling.

Failures

High load and ambient temperature can cause thermal overload of integrated circuits. Finally, an important indicator for an IC is the junction temperature: the junction temperature of any IC should not exceed 125-150°C to avoid excessive stress. In fact, ICs must be operated above their maximum rating and current can lead to electrical overload, which can lead to catastrophic failures. For example, be aware that failures in the cooling system (such as increased heatsink and fan temperatures) in potential electronic components such as laptops can cause integrated circuits to heat up quickly. Discharging

Static

Electrostatic electricity generated during the production and storage of integrated circuits m, can often wear out internal circuits due to the triboelectric effect. Integrated circuits are more prone to error when exposed to electrostatic discharges. c The resulting vehicle fields induced in the integrated circuit can destroy the oxide layers and compounds affecting the component and/or increase the current, resulting in overheating.

How To Fix Integral Ic Failures

Schematics are always very easy to troubleshoot and troubleshoot, especially when they are already installed on the PCB. You can at least fairly easily determine if a chip is really bad and should be replaced using the following methods:

Perform an absolute visual inspection

And here, physical damage to integrated circuits, of course, will lead to malfunctions. A visual inspection of the chip can reveal issues such as cracks, chips, and charring, which may be caused by excessive mechanical stress or overheating.

Check Shorts

One of the best ways to determine what condition a chip is in is to conduct a thorough short circuit test. You can test Bermuda with a DMM by following most of the steps:

1. Set the multimeter for continuous operation

2. Switch all the pins on one side of the IC and connect them to different test leads on the multimeter

3. Check with the remaining multimeter probe anyone who points to the contacts if the chips: more than 50% of the contacts have continuity, then most likely each chip is shorted

Integrated circuit temperature check

Turn on the device (or turn on the chip inputs for 10-15 seconds)

Place your fingertip on the surface of each integrated circuit to check its temperature
