When properly used, a strap will dissipate most of the charge that you build up by normal human activities like moving your arm or doing normal work. When handling an entire circuit board though, it gets a lot more complicated. Now the charge build up has many different paths it can travel down.

Please note: in exceptional cases, the top layer can be affected by acids, for example from the human skin. To protect the conductive layer, you can apply a transparent film or use the adhesive side on top. You're probably asking, why should I care about ESD? Well, the answer is because ESD can cause a lot of damage to electronics.

Application domains

Hualibao Co., Ltd has won 20+ awards, is spread across 53000 ㎡ area, holds 300+ factory employees and has a partnership with 50+ countries making it a leading electrostatic film manufacturer. There's a catch though, there are materials called dielectrics that usually resist the flow of electrons. You never know where the charge will go, and if it will go into a part and across something sensitive that it will do damage to. It's like playing Russian roulette, you simply don't know and shouldn't take the risk.​ In addition, PMMA film also has excellent optical properties. Due to its high transparency and low dispersion, it can be used to manufacture high-definition lenses and optical components, such as camera lenses, spectacle lenses, telescope lenses, etc. At the same time, PMMA film is lighter than glass, easier to process and transport, and can better replace glass in some occasions.

That means we can focus on the items in the work area, and also on controlling the humidity to prevent it from dropping to lower levels.​ Let's have a little fun and figure out how to make the biggest ESD that we can.​ We can do the following:

Length

If you ever dip into the details of how electronic parts are made, usually there are many conductive paths in the part and they are isolated by some kind of insulator, or dielectric. It is suitable for all kinds of painting parts, oil spraying parts shielding and colour protection.
