Laser Seam Welding Of Electronic Packages Using Galvo Scanners
One of the methods used in laser seam welding is to move the workpiece to be welded under a laser galvo scanner head. The galvo scanner provides numerous additional control features, for example, expanding the laser source’s effective fine spot size to the seam width, laying a complex welding pattern over the motion path to create high-quality welds, increasing throughput, and taking advantage of higher power laser sources.  Continue Reading..

Fast Steering Mirrors (FSM) - Design, Performance, And Tuning Of Piezo-Based Mechanisms
In free space optical communication (FSO), large amounts of data are “beamed” between two points – on earth, on aircraft or between satellites in space. Fast steering mirrors (FSM) are one means to compensate for disturbances that could keep the laser beam from hitting its target receiver precisely.   Continue Reading..

Multi-Axis Stages: Why Custom Aligned, Tuned, Error-Corrected XYZ Assemblies Are Better
Multi-axis precision motion at the micron or sub-micron level is required in many industrial automation processes as well as in test and metrology applications. Users of such motion systems often ask: Should I just get the individual components and bolt them together myself, or rather specify a complete XYZ system, mounted, aligned, and tested by a specialist? The answer depends on expectations, performance requirements, and budget.  Continue Reading..

What Is The Difference Between Parallel Positioners And Stacked Serial Kinematics?
When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play.  Continue Reading..

POSITIONING EQUIPMENT SOLUTIONS

Precision-class XY stages are suitable for applications that require fast precision positioning. When switched off, the drive holds the stage stable, reducing energy consumption and heat generation.

The PIMars Nanopositioning Stage is a high-precision nanopositioner for up to 3 axes. This product features parallel kinematics for faster response times and higher multi-axis accuracy.

The M-545 Microscope XY Stage features a stable platform for P-545 PInano® piezo nanopositioning systems, a travel range 25 mm × 25 mm, and a low profile for easy integration. 

The PIFOC High-Load Objective Scanner is a dynamic system with a long travel range and features the highest linearity, stability, and control dynamics due to direct-measuring capacitive sensors.

PIFOC Objective Scanning Systems feature nanometer precision and high feed force with walking drives, accurate position measuring with an incremental encoder and quick, efficient software integration.

The L-836 linear stage series with precision ball screw is suited for industrial applications that require high performance in compact design. High-performance is achieved by high resolution stepper motors, high precision cross roller bearings, and precision linear encoders. The optional foldback allows the motor to run along side the stage reducing overall footprint of the system.

The N-480 series miniature motorized kinematic optical mirror mounts are equipped with PI's high precision PiezoMike motors for ultra-high resolution angular adjustments in two tilt axes (θX and θY) down to 0.3 µrad steps.

The H-840 hexapod series is universally applicable for tasks in precision positioning. Some variants are optimized for high dynamics and can for example, be used for simulating motion whereas models with gearhead support are suitable for heavier loads.

POSITIONING EQUIPMENT VIDEOS

  • Dr. Cliff Jolliffe, PI's head of segment marketing automation, explains how motion and control solutions from PI help address the industry's needs. Advanced motion control algorithms and high performance linear stages and rotary stages can improve the precision, quality and throughput in laser micro hole drilling. The combination of fast focusing and nano-positioning scanning stages allows for a highly controlled hole taper.

  • The production of computer chips starts with the separation of individual dies from the semiconductor wafer. Laser dicing has many advantages over physical cutting equipment.

  • Sensitive electronic assemblies and micro-systems are sealed hermetically to increase lifetime and performance. Laser seam welding is the preferred process to allow very accurate seams with small radii. Coordinating galvos with motion stages for the best results, is made easy with latest software, motion hardware and motion controllers from PI.

  • Before an electronic chip can be purchased, 400 to 800 production steps have been run through. At all critical points during manufacturing, inspection processes are essential to ensure the high quality and reliability of the final products. This video provides more on wafer inspection and metrology with air bearings and piezo nanopositioning stages.

  • Scott Jordan, Physik Instrumente’s Head of Photonics, explains how PI’s motion systems enable simultaneous active alignment of several optical components achieving 99% reduction in alignment times.

  • This presentation, from the APS March 2021 Meeting by Shannon Ghorbani, will give an overview of what a nanopositioning system is, and more importantly, how this versatile tool can be used across a range of physics applications.

  • In a follow-up to our first video with Scott Jordan at PI from day 1 at Photonics West 2022, we bring you part 2. He further drove the point home regarding the need for solutions featuring high-speed automation, and high-throughput and cost-effective manufacturing, and showed us tangible examples of how PI is rising to the challenge.
