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

In answer to your question no. Fiducials should always be as far apart from each other in both directions (X,Y) as possible. This will allow ANY placement machine to calculate the EXACT location and rotation of the PCB, and therefore correct the moun

Some machines may require that the two locals be used to calculate a center point where some (probably most) just use them as a second positional identifier. The fiducials are programmed as just XY and just prior to placement the machine will read th

Hi all, I agree with all the postings above, but I have a few ammendmets: (How is my english so far?) The purpose of the so called "local fiducials" was in the old days, when "board stretch" was a factor. At least people think that was a big matter..

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.

Hello, I need an advice regarding the next issue: in the case of Assembleon Topaz or Emerald SMT machines, is there necessary to teach first the block repeat coordinates and after that the PCB fiducial coordinates when you do not have these coordina

Hello. Our company recently bought a Samsung CP40V pick and place machine. It works very well, the software is intuitive but we have one problem. Is there a way to manually set fiducial position after machine failed to recognize it? For example, duri
