From my experience,  I worked with Dek265GS and Dek265GSX 2d
inspections. After evaluating for about a year, I concluded Dek has some
serious technical issues to overcome to make 2d inspection more
practical for production. Some of issues I encountered are:

- Programming is difficult and time-consuming by comparison with simple
MPM 2di programming. It has complicated programming structures like
stencil inspection only, stencil+board inspection, board inspection only
etc. For an example, if fid marks are re-taught after a while for some
reason, taught-inspection sites are no longer valid. May require
reprogramming.
- 2d inspection is very slow on Dek265GS/GSX. 2d inspection on Infinity
is faster and acceptable.
- Unacceptable faulty inspection failures (even at 50% tolerance).
Simple inspection sites like 1206, 805 or 603 are problematic after some
successful inspection cycles.
- Inspection windows slowly drift out of programmed inspection sites
after few inspections, or after several dozen board inspections. I
noticed a similar problem with Infinity/Horizon at a Dek facility.
- It does not work well with homeplated or other non-four sided stencil
openings and board pads.

It maybe unfair for Dek, but I was not successful to make Dek 2di to
work like MPM 2di. Dek printers are robust machines and provides
excellent engineering support. Dek 2di is good for sales / marketing but
not practical for production use.

There was a posting a few weeks ago asking if anyone had any success
using
the 2D paste inspection on a DEK screen printer. I didn't see any
replies,
but I'm just starting to evaluate it's potential here, and am very
curious
to learn what others have experienced with it's use, and or success.

Email me offline if anyone prefers.

Thanks
