Hello all, Just a quick intro as I am new to this group... My name is Phil, and I work for a small electronics company in the Channel Islands. We make boards for many companies. I am the Mirtec MV-3L user, and I am intrigued by this thread. Our MV-

I will go with Hegemon and Swag, our mirtec has those delays too, our system run locally, and when the hard drive gets full it crash, so we had to install a second hard drive of 1TB and save all pictures there like a backup we run it every weekend, n

Is it possible to Design out the fiducial and use the local fiducials on the panelized boards? Cal

I would rather take Bobpan's advise. If the placement is calculated from the center of two fiducials, than the placement should be off by 1/2 of the distance of the two fiducials, but not by the offset of that one fiducial. However, your approach in

Can anyone tell me if they are aware of any pick and place machines that can use 'randomly placed' local fiducials? Now, let me explain... Our machines (Contact 3S, and 3AV machines) can use local fiducials in several ways. We can use a single center

The algorithm in our machines calculates the coordinate of the centre point between the local fiducials, compares it to the theoretical coodinate in the program data and applies any difference found as a "percentage" correction to all placement coodi

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

1. Read the manual. It's pretty good, and an easy read. Most tech guys could read the manual and have a good start. 2. Call Mirtec, they should connect you with a local rep. who may or may not have some machine knowledge. They may want $ if the m

Can you elaborate? If the point of local fiducials is to find the center of the part how could it matter on some machines and not others....?

By the way: I've also used the corner pads as if they were locals. You can take a bitmap-picture of the pattern, store it and refer to it as a fiducial. Works great and you're sure they don't wander all over the place w.r.t. to the component's XY.
