Sigma-automation

Full automation

Sigma bond testers are modular by design and come with game-changing automation capabilities for automatic loading, testing and analyzing. The Revolving Measurement Unit (RMU) houses up to 6 sensors that enable continuous testing. The software includes vision and deep learning technology to eliminate human errors. 

 

Wafer-loader-W8

Wafer loader

Integrate the Sigma W8 with an independent wafer (un)loader for hands-free bond testing. The wafer handler automatically loads, aligns and transfers the wafers from the cassette onto the bond tester. The cassette mapper detects empty slots and ensures safe wafer handling.

Lift pins

The system gently secures flat and warped wafers with the soft, flexible tips on the PID controlled  wafer lift pins.

Sigma-W12-2022

Upgrade to Sigma W12

The Sigma W8 is upgradeable to the market-leading Sigma W12 bond tester, which can test wafers up to 12 inches (300 mm) fully automatically. The Sigma W12 comes with a 600 mm X stage to test bumps down to 20 µm. The upgrade possibility makes the Sigma W8 a future-proof investment.

Full automation

Eliminate human error and save production costs.

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

No more cartridge
