Because static charge builds up as you move around, you must ground yourself from time to time while working on Static Sensitive Products. A good rule of thumb is to re-ground yourself every time you need to touch a component.
Anti-Static Wrist Strap
ITak computer repairing as an example. IF repeatedly grounding yourself is too tedious, you can wear an anti-static wrist strap. Attach one end of the strap to your wrist and the other to bare metal on your PC case for automatic protection from static charge. An anti-static strap is a good investment if you perform regular maintenance on your computer. Anti-Static Mats and Bags
Use anti-static mats if you need a temporary place to store components while you are working on your computer. Set hardware parts on top of these mats to block the transmission of static charge. For long-term storage and shipping, anti-static bags are the industry norm. Place any component you want to protect inside an anti-static bag to protect the device from static discharge.
