Inspection Solutions

Pass through defects are anything but uncommon in manufacturing. Regardless of the variables involved, it’s imperative to ensure that all products are correctly manufactured and assembled. By utilizing robust inspection solutions in manufacturing processes, companies are able to ensure the highest level of quality in their products.

Coherix developed the Tru3D™ vision platform to help facilitate the stringent inspection requirements in the manufacturing environment and to solve your toughest inspection problems. The Tru3D solutions are built on a family of robust 3D sensors coupled with our proprietary i-Cite™ software platform. Tru3D utilizes rich 3D data sets to identify and eliminate pass through defects in the manufacturing process.

Compared to 2D vision systems which are vulnerable to environmental influences, changes in part color or contrast, Tru3D is more reliable, simpler to use and more affordable to own. While designing Tru3D, we had five goals; minimize the effects of process noise - such as ambient light and part color/contrast - use 3D information for 3D parts, keep it as simple as possible, use redundant information at all opportunities, and log information for future data mining. With customizable applications, we are able to address a myriad of problems that may arise in your production processes.

By seeing in 3D, we can dramatically improve the robustness of error proofing applications. When you reduce variation, costs go down, quality increases and you shorten the time to bring new products to market. The key? You have to see variation in order to reduce it.

OPIS™ (Optical Precising Inspection System) is an on-the-fly system for X/Y/A location and 2D inspection of semiconductor components.  OPIS uses a high resolution camera and a sophisticated LED lighting system to generate images of the bottom side of BGA, QFP and QFN. This unique product offers a range of features for the increasing demands in 2D inspection.

OPIS also incorporates electronics to monitor two separate arm encoder inputs and a strobe controller for flashing the lights. The i-Cite™ NxT software harnesses this hardware to collect images, processes images and determines the pass/fail status of the part(s).

Vision Chip™ 

i-Cite's Vision Chip functional modules are why we can respond to you so quickly and completely. There are more than 120 of these highly optimized software modules containing algorithms, functions, controls and parameters that allow us to:

  • Configure Vision Chip parameters to fit your application, including creating custom panels, displays and collection reports
  • Drag and drop Vision Chips into the virtual circuit diagram
  • Support all applications with single version software

Each configurable Vision Chip module performs several high-level functions, such as waiting for a part-in-place signal, finding the location of an object, or inspecting defects.

Each Vision Chip has a configuration panel with built in graphical and statistical displays that allow you to see exactly what is happening at every step of the imaging processing operation...down to the pixel level, if desired.

Image Processing Vision Chips provide the algorithms and parameters for processing the machine vision application. Sub-pixel algorithms maximize the accuracy of measurements.

Communication Vision Chips provide communication between the i-Cite application and the mechanical system on which it is running.

System Vision Chips provide the infrastructure for controlling the flow of the circuit(s) in the project.
