Hi, Can anyone explain how BGA optical systems work on proffesional systems? What optics is used?( optical prisms or mirrors only)

Thanks for the reply. So a mix of two images is made by optics(2 prisms) and ONE camera shows the result? Or there are two cameras and a mix of two images is made in video mixture device?

Thank you for your reply. Are you sure that it should really work as drawn? Or the mirrored ray( blue colour) will go differently because there is a total internal reflection? And the correct path of the mirrored blue ray is like that green ray?

Not like that. Like this. The prism area is a partial mirror. A variable light source at Image 2 is key.

Hi, Clarification...The point I was not sure of was Jane's last post; not Hedgemon's. I was typing while Hedgemon was posting.

Thank you Bobpan! I checked the laser sensor and could see through the glass a small stripe (dash)in the inside lens, just in the middle of it. Thank you again.

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...

Good Day for Everyone! TOPAZ XII can handle 6.5mm height components easily. Is it possible to mount 10mm? The problem is that the picked high component pushes away other placed high component. Camera alignment works well. Please share your experien

The vision on our semi-automatic printers allows the operator to draw a box around a pad for reference. Then as long as both reference pads are lined up on consecutive boards, it's aligned.
