Smart Card Delaminations
Smart Card Induction Coil Defects - Application Note 305
Sample & Method
A non-contact style Smart Card was imaged on C-SAM to look for potential defects along the section of the induction coil running near the bond pads.
Delaminations (black areas) are visible at several points along the induction coil. In addition, the wire bonds do not appear to be bonded to their pads.
