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,

2 fiducial alignment vs 3 fiducial alignment , any opinion ? When do we actually need the third fiducial for alignment ?

how helpful is it to use alignment weighting over fiducial offsets ?

Offsets are there to for an alignment change over the entire board... alignment weighting is, essentially to account for imperfect match between stencil and board, and will allow you to concentrate best alignment to a given portion of the board (give

Hello, can you explain better what do you want to check? Alignment is done based on fiducial check and then you can do some offsets, based on the print. So I am not sure what do you want to say...

If you believe your picture is in the middle and is not skewed, than go to your basics and recheck your fiducial locations and detection. Sometimes these machines recognize something around and give you this error. Try program with isolated pads and

We have DEK265 and a problem with few projects. Normally it works great, but sometimes we have an issue with Alignment out of range error. Currently we have a project where after fiducials configuration in step mode printer shows an error : Align

Hello, I don't have any experience with Juki. Visited one of their booth recently and I was told they use a laser for alignment. How does this work? Is there any advantage over the traditional vision alignment? Thanks!

Since the Laser alignment bit is attached to the head and you don't have to move the part to a camera location, before placing the component on the board it is about the fastest method there is of getting accurate component alignment. With more moder

I had some of these before and they do a decent job. Laser alignment is ok for passive components. Compared to vision systems it has mainly disadvantages. If you have bended lead on IC for example, it wouldn;t catch it and it will place the part. I w
