Right. Fiducial comes with the CAD data or the gerber files. If it doesnt, and you need to create fiducial coordinates, you may use a digitizer or a caliper and make use of the reference pin as the origin. Now if the fiducial camera focus is way out,

How does a fiducial work? I am going to venture a guess as how it ralates to the parts you are trying to place... A PCB fiducial is a landmark. The fiducial tells the machine where the board is located in the machine. A single fid can only deter

To clean up other replys I will add that some most all machines have global correction. Most placements are an off sets from pcb 0,0 usually the lower left corner of the board. When the machine locates the fiduitals and these fids are not exactly whe

Get a hold of the "SMEMA FIDUCIAL MARK STANDARD" . It should answer all your fiducial questions. Like the other repliers, THANKS for your concerns about fiducials, they are SOOOOOOOOO important !!!!!!!!!!

Good points Darby!

JD, fiducials are merely land marks. The vision processor will measure the actual location and compare it to the CAD location. It does not care if the design is symetrical, asymetrical or what. In the case of a single center design fiducial (which

Components do not have to be in the framework of the fiducials. It is recommended that the fiducials are at the outer extremeties in at least 3 corners of the assembly however. It is also a good idea to keep a minimum "keepout" area around them of

Hi, We're going to migrate our boards from through-hole to SMT, and I'm dealing with the PCB layout. I've found a lot of references for fiducial marks but none of them states if components can be placed beyond the marks limits or only within the are

It depends on whether the Fiducials are Circuit Fiducials (located on the PCB) or Block Fiducials (located on the Panel) His way would be for Block Fiducials.
