Whether you are manufacturing high value consumer goods or sensitive electronics, MicroTorque electric screwdrivers are designed to bring precision, productivity and quality to your production. Ultra low-torque applications, starting at 0.5 Ncm, don´t need to be demanding. Electric screwdrivers in the MicroTorque range from Atlas Copco are designed to perform consistently and precisely, time after time. The MicroTorque system is flexible, with the possibility to program different tightening torque levels and strategies, with torque angle and speed control, to meet even the most challenging applications. The MicroTorque electric screwdriver provides clear operator feedback – common assembly problems like missing screws, floating screws, cross threads and stripped screws are detected and eliminated. Data can be recorded and used for statistical analysis, for full control over the assembly process. All MicroTorque screwdrivers are designed for use in applications with electronic components, with ESD (electrostatic discharge) certification. ESD certification means a guarantee against damage of electronic components by an uncontrolled electrostatic discharge (ESD) from the tools. In practice it certifies that at no point will the material of the equipment hold an electrostatic potential above 100 V for more than 2 seconds.
