Does anyone have any experience with the Amkor Fusion Quad package? I'm wondering about the coverage of the heatsink slug and it floating the interior leadless terminations apart.

Any designers have any experience escape routing the underpart/interior terminations?

This package has been floated up to us as a possiblity.

Can you physically describe the package or provide a picture? Thanks!

It's like a QFN with a set of QFP leads around the outside.

Looks like a lot of opportunities for problems to me, but folks may have used it, or folks who have totally dialed in QFNs may have ideas.

Wouldn't it be easier to use a dual row QFN?

Have you looked at tsCSP? I think that would be a good options also since it has multiple rows.

I am also curious if the tsCSP is just the BCC reborn - any thoughts?

Wow, they claim 1000 cycles of -65 to 150. I wonder if this was done with the 24mm part. With those tiny joints underneath, they must have exactly matched CTE's with their test boards.

Any chance you will try this out?

Amkor must be really pushing this. Two different ASIC suppliers are proposing it. Looks like if I can't say there is a known problem, we'll get it.
