A Guide To Static Electricity And Pc Building – We Summarize Simple Safety Measures To Take To Shield Your Components.
We have all experienced static electricity shocks from time to time, the hum body naturally builds up static charge, and on the odd occasion this charge can attain a very high voltage and cause a painful shock. The shock is triggered by touching something that has a strong conductive connection to earth. Sometimes it is even visible as a tiny lightning bolt traveling from your finger to the metal object touched. You may not know this but static electricity can be devestating to some computer components. Some computer components work by finely controlling electrical voltages in order to be able to produce the properties they were designed to do. The effect a static shock can have on them is the same as you would expect from wireing a 12 volt bulb to the mains supply in your house. This is of course the worst case scenario, but even a minor static discharge can cause a loss of performance or drastically reduce the components life span. The result would be that a relatively new pc fails years before its time.
So what can you do about this?
Well the solution you decide to opt for should be determined by how often you plan to use the equipment, for example, if you plan to build up the odd pc here and there and carry out upgrades or repair on the odd occasion here and there then a simple low cost solution such as a wrist strap will be ideal. These can be purchased from electrical stores for a very modest cost, the wrist strap is attached to a coiled wire which in turn connects on the other end to a good earth point such as a radiator pipe.

If you are planning to work somewhat frequently on computers, then you may also wish to buy a work mat, this consists of a rubber like mat material which disperses static charges, like the wrist band and all static dispering materials it also needs a strong connection to earth in order to function correctly. A professional computer repair company should however opt for a full antistatic room type setup, this involves replacing the floor with anti static tiles or carpet which is earthed, and using work mats on all bench areas, workers usually wear ankle straps which connect the heel to the static dispersing floor, a fabric strip connected to the foot strap is tucked into the sock to ensure skin contact is made. additionally wrist bads are worn and connected whilst a worker is at the workbench. Static really doesnt stand a chance in this type of environment and is dispersed before it can even develop into a perilous charge. Ofcourse your static equipment should be frequently tested to ensure it is properly connected to earth and dispersing charges, this can be done with an ESD (electro static discharge) testing device.
