Beam 1 FW PEC Camera Assembly – T50742101 Rev. E |
This Document Supports Assembly 50742101 Rev. B |
The PEC (Pattern Error Correction) Camera Assembly, also referred to as the downward looking camera, is comprised of a camera, lens and an illumination module. The PEC camera is used in conjunction with a vision system and specific algorithms to find/locate substrate targets (also referred to as fiducials, pad sites or user defined shapes). Product materials vary from application to application stressing the importance of robust illumination and algorithm schemes.
The PEC illumination offers design merits of wavelength, symmetry, and multiple angles of illumination. Illumination schemes are individually selectable or in concert from the user interface providing optimal contrast from the basic to most challenging of substrate materials. Image accomplishments include but are not limited to: ceramics, organics and polyimide, all of which come in many forms, colors and coatings. Refer to the following chart for a description of the relationship between lighting type and fiducial type:
Light Type | Optical | Color | Fiducial Type |
1 | Inner | Red | Shiny tinned, pads |
2 | Outer 1 | Green | Tinned, bare copper, other |
3 | Outer 2 | Blue | Polyamide (red/orange flex) |
