SEM and FIB: A Powerful Combo for PCB Failure Analysis

CIQTEK brings SEM and FIB together as a powerful team, providing critical support for PCB process optimization, reliability verification, and root cause determination of failures.

SEM High-Resolution Imaging: The "Microscope" for Surface Details

The SEM uses a high-resolution electron beam to capture crisp images of PCB surface morphology. It reveals solder pad plating, intermetallic compounds, micro-cracks, tin whiskers, and foreign particle contamination with exceptional clarity.

Coupled with energy-dispersive X-ray spectroscopy (EDS), the SEM also performs elemental analysis on microscopic regions. This combination lets engineers identify the chemical signature of defects, making it straightforward to spot issues like short circuits, open circuits, corrosion, and plating anomalies.

FIB Nanoscale Cutting: The "Scalpel" for Internal Structures

While the SEM excels at surface imaging, the FIB takes over when you need to see what is happening inside the board. Using a nanometer-precision ion beam, the FIB performs targeted cross-sectioning at the exact defect location. It prepares ultra-thin slices through multi-layer boards, blind vias, and buried vias, exposing internal structures that mechanical sectioning simply cannot reach.

Think of the FIB as a microscopic surgical tool. It removes material with nanometer accuracy, leaving a clean cross-section ready for imaging and analysis.
