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

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

Please who can help me? I am looking for fiducial (cross shape) mark (target mark? Swiss mark?..)specifications used when COB wire bonding on PCB laminate. Pad pitch should be 250umm may be 220umm?). Mainly need to know which are the tolerances

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

Does class 2 vs class 3 PCBs effect variance/tolerance in terms of actual positioning of pads/traces? For example, if fiducial is to be at 10mm. What's the tolerance for class 2 vs class 3? [variance allowed] Does panelization have any effect on t
