hi dave Is there another tool besides SAM (Scanning Acoustic Microscopy)? Regards, Ray

Our present lab went "South." We need a lab that can do temperature/humidity conditioing, convection oven baking, C-Mode Scanning Acoustical Microscopic package inspection and "No-Pb" reflow simulation. We are evaluating a low temperature package dry

MSL 3) By SAM (Scanning Acoustic Microscope) before to remove them from PCB, you could identify if de-laminated or not and the degree of delamination. Best Regards...GS

Hello, I would like to ask for cooments/advices about the inspection of small solder deposits inspection (aprox 4 mills). We tried with X ray and Scanning acoustic microscope but it looks like due to the small size, we could not be sure to get all t

Comments are: * A good looking solder ball does not necessarily mean that you have a good solder connection between the ball and the pad. We've all seen a bright and shiney solder ball on the floor, but that doesn't mean there's a good metalurgical

Hi Grant, just my opinion, I think the concern could be related to the extra temperature the BGAs have been exposed during the Lead Free Reflow Temperature. So you need to check ( data sheet) what is the max temperature and how long the Pb/BGA can w

As you probably know, x-ray inspection has problems positivly identifying cracks or delamination. This task is more suited to scanning laser acoustical microscopy but the cost is very high. It has been our experience that cracks are associated with t

Ron: Good news: Nicolet makes excellent machines. Bad news: I�m unaware of a machine with the capabilities you seek. * X-ray machines lack of resolution needed in relation to the crack geometries encountered within a high density single material.
