Philly Chapter Meeting/Dinner: 3D Computerized Tomography and X-ray Technology - August 17, 2017




The Philly Chapter recently held a dinner meeting at ACI with a Technical Presentation and Demo on:

"Advantages of 3D Computerized Tomography in Electronics"

by Ken Gribble, Nikon Metrology, Inc.



and lots of great networking!



Creating 3D solid models from X-ray images is a new and exceptionally valuable tool to the modern Electronics manufacturing shop. 

Some of the ways 3D Computerized Tomography and X-ray technology can benefit electronic assembly are:

Solder process development of hidden connection surface array and No-lead packages

·              Creating 3D solid models from X-ray data can be used for inspection of a closed assemblies without opening the assembly. This is critical for motors and circuit boards embedded in other assemblies

·              Failure analysis of components, surface mount and thru hole.  3D Solid models from X-ray data can be used for failure analysis of components like capacitors and to better examine internal defects of surface mount parts.

·              Whether with wave solder or Selective solder, IPC class 3 assemblies requires that Plated through holes must be 75% filled with solder.  3D models of the solder fill of the plated thru holes can be used to Tune or trouble shoot a process, and confirm the hole fill.

·              If a single wire embedded in a wire bundle has a break resulting in an intermittent, a 3D model of the cable assembly can show the damaged internal wire.

·              Assemblies with Ball Grid Arrays (BGA) cannot have more than 30% voiding. A 2D x-ray can show the volume of the void, but not the location. A 3D Computerized Tomography model created from X-ray can show the position and shape of the void, and it is more accurate.
