Modern electronics without fail on the board contains from one to several microcircuits. They allow not only to minimize the dimensions of the electronics, but also to achieve improved technical and operational performance. Replacing a microcircuit with a similar one /a>, restores the original performance of the equipment. The main thing is to choose the ideal component from a wide range of spare parts.
Failure diagnostic methods
Professional craftsmen have a fairly large arsenal of diagnostic tools to determine which microcircuit has failed and needs to be repaired or replaced. Radio components can serve for a long time, failure, as a rule, is associated with a violation of operating conditions or significant voltage drops. The following reasons should be singled out as the basis for diagnosis:
- Moisture or any other liquid gets on the product.
- Physical damage due to rough handling.
- Failure caused by overheating or a power surge.
- A combination of several reasons at once in electronics.
Most often, modern electronics suffer from incorrect user actions. Even a small amount of moisture on the device leads to a short circuit. The microcircuit burns out and can no longer perform its main role. As a rule, such breakdowns can be seen with the naked eye.
Peculiarities of chip repair
In fact, only a few electronics failures can potentially be repaired. In all other cases, when thermal destruction of the microcircuit has occurred, it needs to be replaced. This is the most reliable way to restore performance. Repair can be done in the following cases:
- damage to one of the contacts of the microcircuit;
- solder got on two contacts at the same time;
- minor damage to the case, insulation;
- contact drop due to vibration.
Professionals try to replace a damaged chip as soon as possible. Due to the large assortment of electronic components, finding an analogue is not difficult. And a chip repaired by replacement will have the maximum degree of reliability.
