| INSPECTION PROCESSES |
| As agents of the counterfeiting world develop better techniques to exploit known countermeasures,
it becomes more critical for front-line companies such as NANTIAN to augment inspection standards
with improvements to the process. NANTIAN has incorporated forensic techniques into our proprietary'up
to 78 point inspection'checklist, allowing us to quickly adapt to changing conditions. Our specially
trained technical team's ability to apply forensic techniques to investigating results and handling
unforeseen and variable situations is where the rubber meets the road. |
| 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

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.
Some examples of how NANTIAN's training has proven effective in combating new
emerging threats over the years: |
- Prior to its adoption in standards, NANTIAN implemented microscopy to identify counterfeit dies and
performed 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. |

- Utilizing our XRF machine to detect traces of uranium from product shipped out of Japan after
the 2011 Tohoku earthquake
- Using multiple points of interest on the X-RAY machine's comparative software for more granular
automated inspection
- Revealing legitimate contracted die use resulting in a "non-conforming" mismatch between the die
manufacturer and the physical component manufacturer

| 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.
