The risks posed by counterfeit and fraudulent electronic components are substantial – especially for aerospace & defence and other hi-rel industry applications. Operations director Ian Walker explains how accredited independent distributor of EEE components Princeps helps mitigate these risks for its customers


Counterfeit mitigation Industry awareness of the scale of the problem that counterfeit parts in the supply chain pose – especially for obsolete or hard- to-source components – has grown over recent years. Princeps takes this threat very seriously, placing quality at the centre of its entire operation. The company has invested heavily in its in-house test and inspection laboratory in recent years, supporting the deep subject matter expertise of its inspection and quality assurance team with advanced technologies.


Test services & techniques Princeps understands the critical importance of precision and reliability in the electronics industry. Its state-of-the-art equipment and advanced testing services are designed to ensure the highest quality for your electronic components. Inspection techniques include: ● External visual microscopy: to gain detailed insights into the structure and integrity of your components using high- resolution microscopy. ● X-ray microscopy: to detect internal defects and ensure the quality of your components through advanced x-ray visual inspection. ● X-ray fluorescence (XRF): to accurately analyse the elemental composition of your electronic materials with cutting-edge XRF technology. ● Chemical testing: to verify the performance and reliability of your components under various conditions using specialised heated solvent testing. ● Decapsulation services: to access and analyse the internal structures of encapsulated devices with precision, using a controlled decapsulation process.

Kitting out the test & inspection lab Princeps remains committed to delivering the highest quality in-house testing services for electronic components. Our state-of-the- art test and inspection lab is equipped with


Our Glenbrook JewelBox system offers advanced x-ray imaging to thoroughly inspect electronic components. This non-destructive testing (NDT) technique enables us to examine internal structures, detect hidden defects, and ensure proper assembly without dismantling the component or causing any damage.


X-ray fluorescence (XRF)


Employing the Fischer XRF, we conduct non-destructive elemental analysis and material characterization. This technology is essential for verifying the composition of materials, detecting impurities, and ensuring compliance with industry standards such as RoHS. Chemical testing


Our dual hotplate set-up facilitates rigorous solvent testing to assess the chemical resilience and integrity of electronic components. This process is crucial for determining the durability of components and determining whether a device has been resurfaced.


Acid decapsulation


With the Nisene JetEtch system, we perform precise acid decapsulation to expose internal structures of electronic components. This technique is used for failure analysis, authenticity verification, and detailed inspection of the die and wire bonds within the components.


Whether you need precise testing, reliable results, or expert analysis, Princeps should be your go-to partner for all your electronic component sourcing needs.
