Bzzzzzz zap I can feel some static!


StaticESDStatic
static electricity
noun
  1. a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
 
(Scientists believe that it is not the rubbing or friction that causes electrons to move. It is simply the contact between two different materials. Rubbing just increases the contact area between them.) Static electricity is the imbalance of. positive and negative charges.

Walking across a rug can produce a static electricity voltage of up to 12,000 volts, but static voltage is not life threatening. So it is possible to damage a hard drive with static electricity that is not even felt by the person because it is at such a low voltage. Also, computers become increasingly susceptible to static electricity damage as more and more circuitry is built into them.
The main components affected by these devious charges are semiconductors. This is because they incorporate various delicate components, and when a negative charge is discharged onto it by virtue of static, it causes failures, as there is no conductor that can dissipate, hence causing damage.
Semiconductors, include diodes, microchips, transistors, etc.
Static electricity, causes damage to sensitive electronic components, so if one brings it near electronics, there will be failure.

So how can we address this?

ESD Protection

The electronic industry has placed a growing emphasis on reliability and quality assurance. ESD damage toElectrostatic Discharge Sensitive Devices (ESDS)  can be minimized by using ESD control measures.

  • Handle electrostatic discharge sensitive devices (ESDS) only in an ESD protected area (EPA)
  • Avoid electrostatic potential differences and electrostatic discharges
  • Use wrist straps, approved footwear and floor combination for personnel grounding
  • Wear properly fastened dissipative garments
  • Avoid electrostatic generating materials (normal PE, PVC, PS, etc.) inside an EPA
  • Do not expose ESDS to electrostatic fields > 100V / cm (10 kV/m) !
  • Use only approved ESD protective packaging materials
  • Awareness, personnel training, continuous monitoring are essential for maintaining a static control program
