Sigma Lite

Low cost bond tester

Proven Sigma performance

Sigma lite is a low cost of ownership bond tester that grows with your company. It gives you a low-cost entry point without sacrificing performance to meet future demands. For more advanced and automatic bond testing, the Sigma Lite is upgradable to a full Sigma bond tester, which comes with higher specifications in:

  • Sensor accuracy and resolution
  • Larger X stage
  • Superior axis speed 
  • Cameras and illumination
  • Dual monitor support

Sigma

Sigma is the most advanced bond tester. It is modular by design and comes with game-changing automation capabilities. 

Sigma-automation

Automation

The Revolving Measurement Unit (RMU) houses up to 6 sensors that enables continuous testing. The software includes vision and deep learning technology to eliminate human errors. 

Single measurement unit / Single load cell cartridge

Single test heads

You can also equip the Sigma with single heads for shear (SMU) or for Push and Pull (PMU). All test heads come with the same specifications as the RMU in terms of maximum forces and accuracy. There is no need to readjust the microscope when you do switch cartridges. They all share the same test point.

Handlers

Robotic handling ensures safe load and unload of applications and avoids handling error and damage. We offer handlers for:

  • Wafers (EFEM)
  • Waffle trays
  • Magazines

Easy programming

The open Sigma software enables easy programming of total automation steps, positions, and commands. The automation editor employs camera visualization and intelligent wizards.

Smart vision cameras

See the unseen with up to 3 live camera options. Bring out the features of interest with images or videos using high-resolution cameras, flexible LED illumination, and fantastic image processing options.

Tool alignment

Precise tool alignment is essential to test the correct bonds correctly. We offer several solutions for perfect alignment:
  • Self-aligning shear tool
  • Deep access
  • Revolving Measurement Unit
  • Concentricity correction

Fiducial recognition

Define recognizable shapes, patterns, or marks as a global or local reference for positioning and automatic tool alignment.

Wire dection

Recognition of components and fine pitch wires that are swept out of position due to process tolerances or part handling.

Grading run

A Sigma offers 2 alternatives to make grading more efficient and consistent:

  • The operator does all the gradings in one step after a sequence of tests, using the microscope or an offset camera.
  • A Sigma can take it one step further and make automatic determinations of the failure modes (auto grading).

Auto grading

Automatically grade the failure modes of the test result images with grading assistance. Optical inspection calculates the area of bulk material remaining as a percentage of the whole.

Image measurement (AOI)

Detailed optical inspection helps you to perform image measurements or to identify the failure modes of the captured test results. For more advanced image processing, filtering, segmentation, and detection of shapes, you can use Automated Optical Inspection (AOI).

Data export

Improve data processing using automatic export and SECS/GEM for tracking and control.

RMU
