How We Test Obsolete Electronic Components

We offer testing on all the components we sell, and all the excess stock components we sell on behalf of our clients.

Initial Visual Inspection

The first stage of the testing process is a detailed visual inspection. Components are examined under magnification to identify any physical defects, contamination or signs of prior use. Markings, date codes, logos and packaging are checked carefully against manufacturer specifications to confirm authenticity.

This inspection can reveal issues such as resurfaced devices, re-marked components, oxidation on leads or evidence of previous soldering. Any discrepancies are investigated further before the component progresses to the next stage.

Electrical and Functional Testing

Electrical testing confirms that each component performs within its original manufacturer specification. Depending on the type of component, this may include functional testing, parametric measurement and dynamic performance checks. Voltage, current, resistance and signal characteristics are measured and compared with datasheet requirements.

Where appropriate, automated test equipment and dedicated test rigs are used to ensure consistent and repeatable results. This stage provides assurance that the component will operate correctly within its intended application.

Advanced Authentication Techniques

For higher-risk or high-value components, more advanced authentication methods may be applied. These can include X-ray inspection to examine internal structures and verify construction against known genuine examples. This non-destructive process helps identify internal damage, bond wire issues or evidence of refurbishment.

Additional techniques such as decapsulation, detailed surface analysis or material testing may be used where a deeper level of verification is required. These processes provide further confirmation of authenticity and internal integrity.

Solderability and Condition Testing

Many obsolete components have been stored for extended periods. To ensure they can be used reliably in modern assembly processes, solderability testing may be carried out. This confirms that leads and terminations remain suitable for secure and compliant soldering.

Where necessary, components can also undergo cleaning or reconditioning processes to restore them to a usable condition while maintaining full traceability.

Other Services

We also offer RoHS conversion, and tape and reeling.
