- 5DX
The 5DX is an
automated x-ray inspection robot, which belongs to the set ofautomated test equipment robots andindustrial robot s utilizingmachine vision . The 5DX is manufactured byAgilent Technologies . The 5DX is a non-destructive structural test x-ray machine, usinglaminography (tomography ) to take 3D slices of an assembled printed circuit board. It is used in the assembledprinted circuit board (PCB) electronics manufacturing industry to provide process feedback to asurface mount technology assembly line, as well as defect capture.The 5DX is one of several tools used by many companies in the
electronics manufacturing services sector to provide a means of structurally testing both the visible and hidden joints of components on assembledprinted circuit board s for defects. These joints are referred to asintegrated circuit to PCB interconnects.tructural Defects
*Bridging (causing electrical shorts)
*Opens
*Missing/damaged components
*Non-wetting
*Billboards
*Tombstones
*Lifted leads
*Solderballs
*Voids (found in Ball Grid Arrays and paste)
*Insufficient solder
*Excess solder
*Misalignment5DX Technology
The 5DX uses a
gantry robot to move the assembledprinted circuit board underneath an x-ray source to be able to see the components' joints that require inspection. The positioning of board is guided with the use ofCAD data, which represents the outer layers of a printed circuit board's electrical design.A predefined laser surface map is used to bring the PCB into the plane of focus (
depth of field ) so that a slice of the component's joints can be taken. A slice will remove obstructions above or below the plane of focus so that only the regions of interest remain (which would otherwise be visible in a 2D x-ray image).History of the 5DX
