An electrostatic spray gun is one of the most useful tools in a do-it-yourself (DIY) set of restoration equipment. You can restore most anything to almost new condition, including electronics. One of the most frustrating things that can happen to someone restoring an electronic device is when the device shorts out. The short circuit, due to static electricity created by the electrostatic charge in the flow of current through the device, sends the components a very weak electrical impulse, which is easily interrupted by touching the parts, or even moving the device in its case.
When you touch the device, the moment you touch the parts, you are making direct contact with the metal parts and that creates an electric field which interferes with the electronic field that is responsible for the operation of the device. The electric field then shorts out the component, sending it into a permanent non-operating state. This is called shorting out the component. Electrostatic discharge is often used to remove such parts.
If you know how an electrostatic spray gun works, you will be able to repair nearly all of these problems yourself. The first thing to understand is that electrostatic discharge is caused by the movement of charged particles. The particles have an electric field which is created by something like a static charge. When the particles move, the charge is disrupted, and the movement gives off a surge of static electricity.
The spray gun shoots the spray through a wire feed system. The component is attached to the wire feed with clips. The gun sprays the charged particles through the feed system until they encounter the charged surfaces on the exterior of the component. These electrodes are designed to be strong enough to withstand the electrostatic charge, but are very thin, so the gun must be used slowly to avoid damaging the component.
You can use this type of gun in many different applications. A common place to use these guns is in a case where a component or piece needs to be re-located without damaging the entire unit. In this instance, you want the gun to release the Particle into one area, so the other parts or pieces are not damaged in the process. This can be important for some electronic components such as microprocessors and connectors, where damaging the wires and other components during the relocation process could cause them to fail or even become unstable and stop functioning altogether.
Electrostatic discharge guns can also be used to quickly relocate metal parts such as screws. You want to make sure that you use the right power to properly power the gun. A small initial burst of electricity can be sufficient to quickly move a screw fastened to a particular component. The power supplied to the gun should be enough to move the part at a rate faster than the speed of the spray itself. For fast moving screws, you may also want to consider using a drill press, which has a continuous flow of drill air, which the electrostatic discharge gun can then use to quickly spray the part, giving it just the right push to allow it to pass through the small holes created by the screw.
How does the electrostatic spray gun operate? First, when you press down on the trigger of the gun, a small amount of charge will be released, which begins to charge the area being moved. As the charge builds, it will cause the Particle to be propelled from the gun at a very high velocity, which will make the Particle travel very far away from where it is being placed.
The great thing about an electrostatic spray gun is how quickly it can be started. A small amount of charge can be stored within the Electrostatic Gun, and it can be ready to fire in a matter of seconds. The gun fires as soon as the trigger is pulled, which makes them great for use in tight situations such as close-quarters combat situations, or even confined spaces.
