Guarding against static shock requires the use of an ESD material such as conductive, anti-static, or static dissipative plastics to minimize risk. Static shock can destroy sensitive electronic components, erase or alter magnetic media, and even cause explosions. Materials with ideal ESD protection require 106 ohms/square to 109 ohms/square. Anything outside of this range still leaves electronic components unprotected.
At SSI SCHAEFER, we only manufacture electrostatic dissipative ESD products. Each SSI SCHAEFER ESD product falls within the recommended range guidelines that are suitable for a wide range of electrical components.
The Difference between Dissipative and Conductive
Electricity at rest is static electricity. The transfer of electrons that occurs upon sliding, rubbing, or separating material generates electrostatic voltage. The discharge of this action results in a mild to painful shock. When electronic components are subject to electrostatic discharge, those items are typically damaged—even with low voltage. Employees are usually the prime causes of electrostatic discharge during assembly or shipping of electronic components. However, even when an approved electrostatic dissipative container (ESD) is used, electronic components are still at risk depending on the materials used during the manufacturing process.
|>1013||Insulative||Insulators and base polymers. These materials are not protective against static electricity.|
|1010 to 1012||Anti-Static||Initial charges are suppressed, but may only be surface resistant.|
|106 to 109||Dissipative||No or low initial charge. Prevents discharge to or from human contact.|
|103 to 105||Conductive||No initial charge, but still provides an easy path for bleed off to another object.|
|1 to 103||Shielding Composites||Employs nickel coated carbon fibers to omit EMI only in specific products.|
|10-3 to 1||Carbons||Carbon powder and fiber.|
|< 10-3||Metals||Stainless steel, bronze, and copper.|
Not All Containers Protect Equally
With conductive containers, a low electrical resistance allows electrons to flow across the surface or through the container and ground to another object without obstruction. This conductive process of moving the electrical charge from a container to another object can be dangerous and is not the best solution for a manufacturing application.
Protect Your Electronics Wisely
With electrostatic dissipative (ESD) products from SSI SCHAEFER, the charge flows to a ground position in a slow and controlled manner. Dissipative materials have a surface resistance equal to 106 ohms/square but less than 109 ohms/square. The risk of electrostatic charges are extremely low, and ESD containers prevent discharge from human contact.
