Electronics & Semiconductor Materials Testing
Electronics and semiconductor devices operate at the limits of materials science — where features are measured in nanometers, interfaces are atomic layers thick, and a single defect can compromise an entire system. Materials failures in electronic assemblies are often invisible to conventional inspection, requiring advanced microscopy, elemental mapping, and nanoscale characterization to identify and explain. Genuine Testing provides independent, third-party materials testing and analysis services for electronics manufacturers, semiconductor companies, PCB fabricators, and quality or reliability engineers. Our capabilities — including SEM, TEM, STEM, FIB/SEM, EDS, EELS, surface analysis, and NDT — are specifically suited to the dimensional scales and material systems that define modern electronic devices.
Why Electronics & Semiconductor Testing Requires Nanoscale Capability
The failure mechanisms that compromise electronic components cannot be observed with optical microscopy or resolved with bulk analytical techniques. Solder joint cracking originates at grain boundaries and intermetallic compound layers measured in microns. Thin film delamination involves interfacial chemistry at atomic scale. Electromigration voids form within metallization lines just hundreds of nanometers wide. Bond wire failures involve intermetallic growth at interfaces measurable only by TEM.
Genuine Testing’s instrument suite — SEM, TEM, STEM, FIB/SEM, EDS, EELS — provides the resolution, contrast, and compositional sensitivity required to characterize these features with precision. Combined with expert interpretation and structured reporting, our analyses deliver actionable answers to complex electronic materials questions.
Our Electronics & Semiconductor Testing Services
Failure Analysis of Electronic Components & Assemblies Electronic failure analysis demands a systematic, non-destructive-first approach to preserve forensic evidence before any cross-sectioning or destructive testing is performed. Our investigations cover:
- Solder joint cracking and fracture (thermal fatigue, mechanical overload, brittle intermetallic failure)
- BGA and QFN package delamination
- Wire bond and ribbon bond failures (intermetallic growth, Kirkendall voiding, heel cracking)
- PCB delamination, conductive anodic filament (CAF) growth, and measling
- Die attach failures and voids
- Thin film cracking, delamination, and electromigration
- Corrosion and dendrite growth on PCB surfaces and component terminations
- Contamination-induced failures
Scanning Electron Microscopy (SEM) & EDS SEM provides high-resolution imaging of electronic component surfaces, fracture interfaces, solder joint morphology, bond pad conditions, and PCB surface features. Combined with EDS elemental mapping, SEM enables identification of contamination, corrosion products, intermetallic compound distribution, solder alloy composition, and plating chemistry — with spatial resolution down to the submicron level.
SEM is the primary imaging tool for solder joint fractography, bond wire surface analysis, PCB surface defect characterization, and contamination investigation.
Transmission Electron Microscopy (TEM) & STEM TEM provides near-atomic-resolution imaging of thin film interfaces, semiconductor device structures, intermetallic compound layers, grain boundaries, and crystal defects. STEM combined with EDS or EELS delivers elemental mapping and bonding state analysis at atomic spatial resolution — essential for understanding thin film failure mechanisms, diffusion barrier performance, and interface chemistry in advanced semiconductor devices.
TEM is critical for:
- Characterizing intermetallic compound layers at solder-pad interfaces
- Imaging thin dielectric and metal layers in semiconductor devices
- Investigating electromigration-induced voids and hillocks
- Evaluating barrier layer integrity in Cu metallization systems
- Characterizing gate oxide defects and interface traps in transistor structures
EELS (Electron Energy Loss Spectroscopy) EELS provides chemical and bonding state information at atomic spatial resolution — beyond what EDS alone can deliver. In semiconductor device analysis, EELS is used to characterize oxidation states, elemental distribution in ultrathin layers, and bonding chemistry at interfaces where composition and atomic structure both influence electrical performance.
Cross-Section Preparation & Metallographic Analysis Precision cross-sectioning — including mechanical polishing and FIB preparation — exposes solder joint internal structure, PCB layer stack integrity, via fill quality, coating thickness, and interfacial bond quality. Our metallographic preparation services ensure that cross-sections are free from preparation artifacts and are ready for imaging and compositional analysis.
Key parameters assessed: solder void content, intermetallic compound thickness and morphology, plating uniformity, PCB layer registration, via barrel condition, and coating adhesion.
Surface Analysis (XPS) Surface contamination — organic residues, oxide films, flux residues, and ionic contaminants — is a primary driver of solderability failures, adhesion problems, and corrosion-induced reliability issues in electronic assemblies. XPS provides chemical state analysis of surfaces at the monolayer level, identifying contamination species, oxide composition, and surface treatment uniformity that cannot be resolved by EDS alone.
XPS is particularly valuable for investigating solderability failures, bond pad oxidation, adhesion failures in underfill and encapsulant systems, and flux residue characterization.
Corrosion & Electrochemical Analysis Corrosion on PCB surfaces and component terminations — driven by ionic contamination, humidity, and electrochemical potential — causes leakage currents, short circuits, and open circuits that compromise device reliability. We characterize corrosion products, identify ionic species responsible for dendrite growth, and evaluate protective coating effectiveness using SEM/EDS analysis combined with surface characterization.
EELS (Electron Energy Loss Spectroscopy) EELS provides chemical and bonding state information at atomic spatial resolution — beyond what EDS alone can deliver. In semiconductor device analysis, EELS is used to characterize oxidation states, elemental distribution in ultrathin layers, and bonding chemistry at interfaces where composition and atomic structure both influence electrical performance.
Cross-Section Preparation & Metallographic Analysis Precision cross-sectioning — including mechanical polishing and FIB preparation — exposes solder joint internal structure, PCB layer stack integrity, via fill quality, coating thickness, and interfacial bond quality. Our metallographic preparation services ensure that cross-sections are free from preparation artifacts and are ready for imaging and compositional analysis.
