Packaging Inspection

The start of our packaging inspection covers all industry standard elements such as: examination of original sealed packaging, verification of label and marking authenticity, and identification of discrepant reference information. The resulting evidence, however, may be open to subjective interpretation without the integration of corroborating supporting pieces of evidence into a collective profile.

1. Industry Best Practice: Packaging Level

In accordance with following industry defined standards for package inspection,we conduct all inspection steps such as:

Bar code scan

Country of origin

Seal verification

ESD anti-static bags

MSL humidity

Texture and condition of labels

Damage or tampering of packaging

2. Forensic Application: Packaging Level

he standard inspection steps are an excellent foundation, but sometimes lacks depth and doesn't always account for unexpected outcomes. We improve on steps called out by the standards such as when our inspectors examine packaging to verify similar materials, colors, and sizes. Our team is trained to focus on additional vital details such as:

Foreign contaminants either on or inside the box

Inconsistent surface patterns on the outer packaging in addition to labels

Suspicious ink markings on the packaging materials

Component Inspection

The start of our component inspection covers all industry standard elements such as: verification of parts in carrier, analysis of component surface, and examination of leads. As with packaging inspection, the evidence resulting from component inspection may be open to subjective interpretation without the integration of corroborating supporting pieces of evidence into a collective profile.

1. Industry Best Practice: Component Level

In accordance with following industry defined standards for component level inspection, we conduct all inspection steps such as:

Verify that carrier is manufacturer original or after-market

Check pin condition for corrosion, solder, or physical damage

Check for directional scratches indicative of resurfacing

Check for surface damage

Verify Country of Origin marks

Verify accuracy of part markings

2. Forensic Application: Component Level

By nature, standards often have difficulty keeping up with the constant evolution of counterfeiting methods.This has forced front-line entities such as independent distributors bearing the brunt of responsibility to adapt and mitigate new threats in near real-time.

All tenured inspectors have directly experienced multiple evolutionary shifts since the advent of counterfeiting as a trade in the late 90s but it is the culture and mentality that is developed through training paradigms that sets NANTIAN apart.

new emerging threats over the years:

Prior to its adoption in standards, NANTIAN implemented microscopy to identify counterfeit dies and per formed surface analysis.

Prior to its adoption in standards, when sophisticated laser marking equipment was used, our quality team identified a subtle variation in the lettering joints of each character which was indicative of false marking.

Escalated Inspection

As the sophistication of counterfeit material increases, the likelihood of detecting counterfeits utilizing simple visual techniques becomes less likely. It then becomes necessary to utilize specialized tools and advanced techniques to collect vital evidence for positive identification. When utilizing tools, factors such as calibration, tolerances and specification complicate the inspection process which require more expertise to validate results. Even industry standards that address these advanced inspection methods do not provide clear acceptable or unacceptable criteria due to the variability of the results themselves and its complexity.

To mitigate the inherent risks associated with increasing complexity of inspection and potential ambiguity of output data, NANTIAN's Q.C team cooperate with the 3rd party professional testing-houses task force consisting of product SME's and technical engineers. The mission of this task force is to understand specialized tools and their the purpose, evaluate their intended capabilities, and ultimately deploy these tools into the advanced inspection process. An engineering approach to advanced inspection is necessary to ensure our inspectors obtain clear results based on real world performance.

1. Forensic Applications: Escalated Inspection

When standard inspection steps are not enough, our inspectors conduct escalated inspections using tools thoroughly vetted by our engineers for maximum accuracy and relevant performance. These tools provide our inspection team with a scientifically sound platform for obtaining controlled results to which forensic methodology can be applied.

2. X-Ray Inspection: Testing -House Verifier HR CIS Advanced

NANTIAN Components engineers worked in cooperation with Testing-house. engineers to help develop the first high-performance automated X-RAY system of its kind.

NANTIAN helped develop custom functionality such as a locking arm safety feature, a variable-movement compensation algorithm for greater accuracy of automated inspection, and the ability to designate multiple points of interest for granular analysis.

In addition to these custom enhancements, our X-RAY system is equipped with a best-in-class 5 micron focal spot, 715X combined optical and geometric magnification, 40 lp/mm resolution, and high-intensity image intensifier.
