The Reliability And Noise Of Electronic Products

With the daily extension of electronic technology application area

, the problem of electronic products reliability is more and more puzzle the serviceman. There are many problems that influence the reliability of electronic products ; the noise is most important parts. The noise is the general terms of jam signal which cause bad influence to human and equipment, for example, the sound and picture which made people have an unpleasant feeling and signal of machine wrong working. To the noise, you should pay attention to it like fire that you need have enough methods first, or it will waste funds and time.

1. You should know the working condition of electronic products reliability.

The insulation material of electronic products will reduce the insulation degree with humidity and produce leakage current to have noise. So the place where store and place the electronic products must be dry and have enough moisture proof method, and avoid to placing the electronic products in high humidity place or concrete corner.

Because of static function, electronic products are easy to absorb dust, and make insulation of electronic components reduced and temperature of electronic components high, therefore, you must frequently do cleaning of electronic products .

Owing that the metal part of electronic components will have oxidation after contact with air, then there will get rusty; the electric resistance will be changed, and then will be bad contact to have a noise. So you should wipe with enamel to protect metal or weld place. Besides, the acid flux using during welding should be clean, to avoid bad contact.

Because the shake or impact of environment will cause noise, so in the areas of install of equipment components or wiring fixed, there must be shockproof measures.

2. The maintenance of electronic products

As for the maintenance of electronic products noise, there are several methods. First, you should to judge whether it should be maintain or improve according the noise and working status of electronic components, then to find the reason according to stoppage. Once the normal electronic products suddenly have the noise which hasnt appeared before, this condition means the electronic products needs repair. However if the electronic products did have noise since it began to use, this conditions means the appearance of noise is related with environment, working condition and equipment performance.

There are various reasons that will cause the noise of electronic products , so you should find the reasons, then according to the reason to repair it.
