Original Press Release:

ETEL'S New ZAO Force-Controlled Actuator To Better Meet Semiconductor Needs

ETEL is pleased to announce its new ZAO Force- Controlled Actuator, adding to its already broad range of advanced motion systems. Among other applications, ZAO is perfectly suited for semiconductor pick and place, die bonding and probing machines.

Coupled with ETEL’s AccurET controller, the ZAO Force-Controlled Actuator provides the user with a state-of-the-art solution to reduce machine cost of ownership while taking up the next force control challenge!

ZAO is a 30-mm travel actuator featuring a frictionless bearing arrangement and a light moving mass, ensuring very low and repeatable force application as well as low force overshoot at impact on a contact surface.

Built to take full advantage of ETEL’s sensorless Force-Control algorithm, ZAO allows simultaneously a very tight force control accuracy (0.2 N ±10%) and a very high dynamics capability (up to 20 g).

ZAO aims to address the new semiconductor back-end and electronics challenges driven by the new advanced packaging technologies and materials, specifically ensuring the integrity of fragile component or target substrates without compromising the machine throughput.

ETEL S.A. is based in Switzerland with exclusive North American distribution through HEIDENHAIN CORPORATION in Schaumburg, IL. As a leading international supplier of direct drive and motion control components and integrated systems, ETEL supports high tech industry with linear motors, torque motors, positioning stages, and motion controllers/systems.
