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, Classic’s ownership commissioned an engineering 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.

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

X-Ray Inspection:
Focalspot Verifier HR CIS Advanced

Classic Components engineers worked in cooperation with Focalspot Inc. engineers to help develop the first high-performance automated X-RAY system of its kind.

Classic 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.

X-Ray Fluorescence (XRF):
Olympus Delta Innov-X

For the purpose of WEEE/RoHS2, Classic has selected a versatile XRF platform that is able to detect the maximum allowable concentration levels of all non-gaseous elements on the periodic table, including the following WEEE/RoHS2 elements:

  • Lead (Pb) – 1000 ppm
  • Mercury (Hg) – 1000 ppm
  • Cadmium (Cd) – 100 ppm
  • Chromium (Cr) – 1000 ppm
  • Bromine (Br) – 1000 ppm

Chemical Decapsulation:
Rapidetch Negative Pressure System

Rapidetch, like other top-tier acid decapsulation systems, allows for fine control of temperature and acid mixture. All systems are fully capable of etching precise openings in plastic packages of all sizes and compositions. However, acid is a hazardous substance, and safety is of paramount concern to Classic.

To ensure the safety of our inspectors, our engineers specifically selected a negative pressure acid delivery system to minimize the potential for acid to be released into the atmosphere.

Solder Testing: Plato SP-500TP

While not the most glamorous, solder testing is vital when our customers require legacy or obsolete products. To ensure conformity, Classic utilizes the established JEDEC JESD22-B102E method for solder testing using high-precision temperature controls. Our solder environment is segregated to avoid contamination, and offers testing for both Lead-Free (SnAgCu) and Leaded (PbSn) products.

All Surface Test:
Scrape and Solvency

Classic Components utilizes all standard device surface and marking tests, including:

  • 3 parts mineral spirits and 1 part isopropyl alcohol (IPA) solution swab testing
  • Acetone swab testing
  • Physical scrape test utilizing razor blade
  • Elevated temperature test using Dynasolve 750 or 1-methyl 2-pyrrolidinone
