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 !!!!!!!!!!

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

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

Yes I agree with Russ about someone asking up front and everything else. Two tips. 1. Keep the marks at least 5mm in from the conveyor edges of the pcb so that clamping systems do not hide the mark. 2. Make sure the marks are eccentric around the pcb

Joe If you are building these yourself your engineering group should be able to answer your questions, if you will be using a CM they will usually have a basic DFM report which they will gladly give to you as it will make their job much easier if yo

you are welcome, don't forget to set the search window (Fiducial Mark if 1D. then the search Window is set to 3D). Please reply once you have done.

Hi SimionR, Is Glue Process Dispencing or Glue Printing thru Stencil? if Its Dispencing Glue thru a Nozzle then its a controllable process. I have performed it thru HDP-3 Panasonic. Placement of Glue either one DOT or Process must be aligned with th

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

this is the order that I use. 1. Teach pcb origin 2. Teach fiducial location 3. dial in vision on fid in mark info. 4. go into mount and verify that the primary image is on in x/y (after perfoming a teach trace condition) and then do any offsetts if
