The only way I know of to determine the IM layer thickness is to
cross-section the joint, then make an SEM and visually measure the thickness
on the image.

|Subject: Solder Joints
|
|
|Hello all
|I am interested in knowing if anyone is aware of any possible
|methods or
|information regarding testing of solder joints. What I am looking for
|specifically is a way of determining the strength of a joint
|and a way of
|determining the properties (ie: thickness) of the
|intermetallic layer. I am
|not sure where to find such information. I have attempted
|internet searches
|but I have been unsuccessful. Any info would be greatly appreciated.
|Thanks in advance.
