Most of the devices and tools around us that have brought prosperity, comfort, ease in doing things, etc. in our lives are controlled by electronic boards. By looking at our surroundings, we realize that our world is full of electronic boards, without which our life would somehow be disrupted. Since these boards are controlled by electronic components that are assembled on them are, each of these parts according to their nature in the circuit may be due to various reasons including: The use of low-quality parts (which is directly related to the life of the product), the presence of noise, a sudden increase or decrease in voltage, and inappropriate use by the user, etc. can be damaged, the failure of any of them can lead to the failure of a part of the board's functions. or the device or it can disrupt the device's performance as a whole.
Repair and repairer:
In case of failure of electronic devices and boards or the need for spare parts, it is very important to have a suitable reference for repairing and providing electronic services. Is it the right thing to choose and trust any person and group for repairs and providing electronic services? Unfortunately, the words "repair" and "repairman" especially in the field of electronics have a lower position among the general public in terms of semantic load than other job categories, if in practice it is not the case. The work of repairing electronic devices and boards is a very difficult, highly specialized job, requiring high technical knowledge, experience and skill, and the repairmen are its experts.
Since specialized work has a special value and status all over the world and it also brings good income, so there are many applicants for activities in these fields. Since the repair of electronic devices and boards requires a lot of expertise, high knowledge, skill and experience, it is very good to generate income in it, provided that the repair is done in a scientific and principled manner, in accordance with the standards, and ultimately customer satisfaction. This has made electronics experts who have no experience working in the field of repairs, or people who have even little knowledge of this field or have learned it experimentally, work in this field. In this way, according to the apparent failures that are evident on the board or the parts that have visible signs, or based on experience, the parts that are more likely to fail are replaced with new parts, which is called replacement. Sometimes, in addition to the failure of the device or the electronic board, it may cause more serious injuries and result in more financial losses.
