Removal and Replacement Procedures
E l e c t r o s t a t i c D i s c h a r g e
A sudden discharge of static electricity from a finger or other conductor candestroy static-sensitive devices or microcircuitry. Often the spark is neitherfelt nor heard, but damage occurs. An electronic device exposed toelectrostatic discharge (ESD) may not be affected at all and will workperfectly throughout a normal cycle. Although, it may function normally for awhile, then degrade in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but inmany cases, the discharge contains enough power to alter device parametersor melt silicon junctions.
Ge n e ra t in g S t a t ic
The table shows how different activities generate static electricity and atdifferent electrostatic voltage levels.
Typical Electrostatic Voltages
Relative Humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl floor 12,000 V 5,000 V 3,000 V
Motions of bench worker 6,000 V 800 V 400 V
Removing DIPS from plastic tubes 2,000 V 700 V 400 VRemoving DIPS from vinyl trays 11,500 V 4,000 V 2,000 V
Removing DIPS from Styrofoam 14,500 V 5,000 V 3,500 V
Removing bubble pack from PCBs 26,000 V 20,000 V 7,000 V
Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
NOTE: 700 volts can degrade a product.
