Hello Ioan,

As others have suggested, your particular application will most likely
dictate the features that are important to you.

We have a Dage model XD7500VR at our facility. We have great success
using it for BGA analysis after placement and rework. It also works
great for us when we use it to inspect for minimum solder barrel fill in
military thru-hole applications.

Our contact in the Northeast is:

John is a very knowledgeable guy.

Good Luck in your search,

Subject: [TN] X-Ray equipment

Dear Technos,

One more topic: what are your experiences with X-Ray equipment? Which
brand/model would you recommend or not advise?

We are a typical EMS and would like to inspect as accurately as possible
BGAs and leadless. So voids and hole-fill measuring capability is
desired. If possible, we would like to be able to localize an open BGA
joint.

Not exactly looking for big budget laminography machines like the 5DX,
but it should at least be 2D plus rotation capability. Or a regular, not
so loaded 3D system...

On-line and off-line answers welcome.

Thanks,

Ioan
