Images of ESD Damage

Seeing ElectroStatic Discharge (ESD) damage is basically impossible. Damage to semiconductor device structure is NOT visible at ordinary magnifications of an optical microscope. If the microscope is capable of 1000X-1500X magnifications, you just might be able to “see” something. The method used, only occasionally as there is considerable expense, is by delayering and etch enhancement producing high magnification photographs using a scanning electron micrograph (SEM).

“All personnel shall be grounded … when handling ESDS [ESD sensitive items]. When personnel are seated at ESD protective workstations, they shall be connected to ground via a wrist strap system.” [EN 61340-5-1 Edition 1 2007-08 clause 5.3.2 Personnel grounding] Where continuous monitoring is used, no additional testing is required.” [EN 61340-4-1, per A.5.2]

“The wrist band will normally be worn for several hours at a time so it needs to be comfortable while making good contact with the skin. It is a good idea to check the wrist strap every time it is applied. Constant on line monitors can be used so that any breaks will be immediately found.” [EN 61340-5-2 section 5.2.7]
