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

Hello mickd, The Fiducial Marks are normally etched along the vertical side of the PCB, therefore it will not be block by the XY table clamping rails. p.s. try to have a Shiny & Round Fiducial Mark as recommended by Fuji....so that you need not inp

I'm no math wizard, but this is my understanding Did you ever have a spirograph as a kid? Took you about 5 minutes and endless number of lines to create one circle ( and some pretty cool patterns too ). To create a square ( or diamond ) you only n

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
