When we talk about static electricity and how it can affect electronic products, an important point worth mentioning is that static electricity is nothing more than a very basic form of electricity. It is governed by the rules, laws, and properties of science, so it should not be a topic of great mystery for us.
In its most basic form, when two materials touch together and then separate, one material will become "positive," and the other material will become "negative."
Activity to try: Unroll a strip of 3M(TM) Scott Tape,a nds ee how it "jumps" toward your hand. Unwind two pieces of tape,a nd they will repel each other because they are both positive or both negative.
Static can damage electronics at any level of handling. It is most costly during field service, also called field failure. Any time that electronics are handled, precautions must be taken to lesson the chance of caustin damage.
