To many people, static electricity is little more than the shock experienced when touching a metal doorknob after walking across a carpeted room or sliding across a car seat.
The same spark that you sometimes feel and see when you touch something like a doorknob after walking across a carpet can zap a component in the same manner as a lightning bolt damaging a tree.
Sofema Aviation Services www.sassofia.com office@sassofia.com offers Electrostatic Sensitive Discharge training with the primary goal to focus on the understanding of the requirements of the organisation to manage effectively Electrostatic Discharge Sensitive components and devices.
Static electricity has been a serious industrial problem for centuries. As early as the 1400’s, European and Caribbean forts were using static control procedures and devices to prevent electrostatic discharge ignition of black powder stores.
As electronic devices became faster and smaller, their sensitivity to ESD increased.
Today, ESD impacts productivity and product reliability in virtually every aspect of today’s electronics environment.
Static control programs become more effective and less complex if we focus on just four basic principles of static control as follows:
Design In Immunity by designing products and assemblies to be as immune as reasonable from the effects of ESD. Eliminate and Reduce Generation by reducing and eliminating static generating processes, keeping processes and materials at the same electrostatic potential, and by providing appropriate ground paths to reduce charge generation and accumulation.
Despite a great deal of effort during the past decade, ESD still affects production yields, manufacturing costs, product quality, product reliability, and profitability. Industry experts have estimated average product losses due to static to range from
8-33% running into the millions of dollars annually.
The 4 rules of Static Protection:
1. Handle all static sensitive items at a static safeguarded workstation.
2. Transport all static sensitive items in static preventive containers
3. Test and monitor static control process and items.
4. Make sure every party in the supply chain follows above three rules
Many electronic components are susceptible to ESD damage at relatively low voltage levels. Many are susceptible at less than 100 volts, and some components have sensitivities below 10 volts.
Electrostatic discharge can occur throughout the manufacturing, test, shipping, handling, or operational processes.
Component damage can occur as the result of a discharge to the device, from the device, or from charge transfers resulting from electrostatic fields. Devices vary significantly in their sensitivity to ESD.
