PI’s New Motion Controller Offers Nanometer Resolution
Auburn, MA — PI (Physik Instru mente) has intro- duced a compact, closed-loop motion controller that provides nanometer resolution for miniature piezo motor actuators. The E-871.1A1N digital servo con- troller is the latest in a series of drivers and con- trollers designed specifically for inertia-motor-based, opto-mechanical actuators (piezo ratchet drives). These drives are widely used in the semiconductor, laser and photonics industries for the fine-tuning of complex systems. The miniature actuators are often employed
as “set-and-forget” mechanisms with an option to make adjustments remotely, where manual micrometer screws would necessitate a system shutdown to allow for corrections. Other applica- tions include the fields of bio-nan- otechnology, microscopy and micro- manipulation. The E-871.1A1N has an inte-
grated power amplifier and voltage generator for piezo inertia drives. It is optimized for PI’s N-472 series of closed-loop PiezoMike precision actu- ators, which provide high stability, a lifetime of more than one billion steps and a low cost of ownership. The E-871.1A1N is equipped with
a data recorder for high speed tracing, ID chip compatibility for quick start- up, and exchange of system compo- nents without recalibration. The con- trollers are delivered with extensive software packages, including support
Endura Intros Tiny Embedded Voltage Regulator
San Diego, CA — Endura Tech nol - ogies has introduced its ET7700, a three-phase 6A switching regulator. According to the company, it is the industry’s first 28 nm embedded volt- age regulator (eVR™). It is integrated inside the SoC
package within a 0.008 in.2 (5 mm2) area and is less than 7.9 mil (200 µm) in height, including inductors. The ET7730 is designed to provide excel- lent performance in a small form fac- tor module, with integrated passives. The ET7700 product family will include a fully-integrated, stand- alone module in 2018. The regulator delivers high per-
formance while using very small inductors (less than 6 nH) and capac- itors (less than 0.47 µF) providing high efficiency, a small form factor, PCB area, and BOM savings, as well as support for high-definition DVFS. Key features include: high-per-
formance 70 to 130 MHz programma- ble DC-DC buck converter; ultra-fast dynamic voltage control (DVC) for DVFS — 100X improvement in slew rate (greater than 500 mV/100 ns); small L/C components for land- side/top-side in-package integration; wide output voltage regulation range of 0.1 to 1.1V; high efficiency, flat over entire load range; seamless, automatic PFM/PWM operation and phase shedding without hysteresis; and built-in, fast digital current reporting in less than 1 µs with no
external components. Contact: Endura Technologies,

As pioneers in industrial soldering Ersa is setting the benchmark as technology leader time and again. Get the best in selective soldering at any level – from SMARTFLOW up to VERSAFLOW and VERSAFLEX. If excellence is your goal, Ersa has your solution!
Highlights Ersa VERSAFLOW 4/55 Highlights VERSAFLEX
Processable area 20” x 20” Use of up to 4 flux spray heads
Product change without loss in production time with the multiwave process
High end selective soldering system for in-line manufacturing concepts
Simultaneous Processing of multiple-up boards in x- or y- direction
Highest Flexibility at lowest cycle time
Automatic cycle time optimization through CAD 4 offline programming software
for LabVIEW, MATLAB, C, C++, C#,
VB.NET, and Python. In addition, a powerful macro program- ming language is available for automation tasks
and standalone operation. Communication inter- faces with a host PC include TCP/IP and USB. An optional joystick is available for manual operation. Actuators with a screw and ratchet mechanism
are designed with a small piezo ceramic block that performs the individual “clicks” based on the input to a controller. The advantage of this design is a very high stiffness and blocking force of up to 100N. Once the encoder tells the controller that a position is reached, the actuator is vibration-proof, shock-
resistant, and stable, with no position drift or jitter. Contact: PI (Physik Instrumente) L.P., 16
