Problem: detection of defects at soldered joint

Posted by: Peter Bergmann , E-mail: bergmann-peter@gmx.de, on March 23, 2000 at 14:58 :

Dear NDT experts,

could anybody give me information concerning the following NDT problem:
I have to detect defects in soldered, non ferromagnetic components with curved surfaces. The 0.1mm - defects (pore spaces) at the soldered joints are located in a depth of up to 5mm below the accessible surface.
A NDE method is required which is suitable for the integration in a manufacturing process. The concerning components vary very much in their shapes. So no scanning ultrasound or scanning eddy current method seems to be suitable.

Thank you very much

Thomas
