iX7059 Module Inspection
Potential engineering use: [Initial die-attach voids and coverage] Compare initial coverage and voids in solder/conductive-adhesive die attach. [Copper-clip attachment integrity] Compare materials and processes at the upper copper-clip joint. [3D void topology and thermal risk] Quantify 3D location and shape of existing solder/adhesive voids.

Initial die-attach voids and incomplete coverage
Compare initial coverage and voids in solder/conductive-adhesive die attach.
Restrict to the layer below the die; silver-sinter pores and upper copper clips are separate problems.
View engineering problem →Copper-clip attachment integrity in power devices
Compare materials and processes at the upper copper-clip joint.
Separate it from die attach and confirm clip thickness, clamping and electrothermal loading.
View engineering problem →Why can the same void percentage imply different thermal risks?
Quantify 3D location and shape of existing solder/adhesive voids.
Pair CT with thermal tests; sample-dependent resolution cannot yield a universal acceptance percentage.
