Well, it would kill the whole idea of having an almost table top ion mill dedicated to cross-sectionning. :-)

Subject: Re: [TN] Focused Ion Beam Milling for Cross Sectioning Solder balls .



FEI dual beam (focus ion beam + SEM) possibly will do the trick.  I have

used it for cross section wire bonds, and look at the crystallography

structure and deformation under thermosonic bonding interface.  Not

cheap, only quarter Mil to 0.75 Mil depend upon what you want to

do...;-).  Reuven, do you have a deep pocket?  It is a wonderful

machine... you can always find someone who has deep pocket and pay for

the service (not cheap either).  Cross section just a piece of cake

(provide your sample is small enough, like a BGA device, not a full

populated circuit board.

Hi Reuven, 

 

I don't have the equipment details. They have a website 

_www.oregon-physics.com_ (http://www.oregon-physics.com)  which is a

bit sparse on information but 

does have a contact link. 

 

They are it appears a relatively new company so I expect that they would

be  

quick to respond. 

 

Best regards, 

Joe
