ESD (electrostatic discharge) is the transfer of an electric charge upon contact between two objects with different electric potentials. On the assembly line, ESD can damage or destroy sensitive electronic components and even set off fires in flammable environments. Worse, this damage doesn't always occur immediately, but will often manifest itself at a later time, affecting product quality and reliability even more.
Furthermore, the ever diminishing size and ever increasing speed of electronic devices and circuitry is only causing sensitivity to ESD to increase.
This is because, as the size of components is reduced, so is the microscopic spacing of insulators and circuits within them, making the whole component more prone to ESD-caused defects.
Ultimately, this results in increased manufacturing costs and decreased productivity.
As part of a campaign to help avoid these issues, in 2014 Ansi 20.20 was amended and DC electric torque drivers were placed in the same category as handheld soldering and desoldering tools. The amended guidelines mandated that all DC driven tools must generate no more than 4 ohms at the engagement point between the screwdriver bit and the fastener being tightened.
No design changes were needed for Kolver’s torque screwdrivers, the first tools in the world certified by the Swedish Institute of Technology, as the standard design has always included a path from the bit-holder to the ground connection powering the Kolver control box
In fact, since 1998 Kolver housings on all handheld tools have been made with permanent ESD-safe injection-plastic compound. As a result, when holding a Kolver screwdriver the operator creates a primary grounding protection that nullifies any interference of EOS (Electric OverStress).
Additionally, Kolver drivers have an ESD-Safe path to ground as per Ansi 20.20-2014 guidelines for ESD Safe manufacturing practices.
If an ESD incident occurs, the charge is dissipated from the bit to the bit-holder, through the robotic cordset to the control box and finally to the ground-wire of the cordset providing power to the control box. (Note: the bits being used must not be painted or coated with any anti-corrosion compounds)
While this has always been the standard design of Kolver drivers, it proved to be most beneficial with the implementation of Ansi 20.20-2014. Lenovo was one of the first manufacturers to begin testing their current toque drivers and evaluating new tools to update facilities worldwide. Through the evaluation, Kolver proved to be the only driver tested that met the new Ansi 20.20-2014 specification and the rest is history. Lenovo is now a Kolver customer and many other manufacturer’s in the electronic industry have followed suit.
