Electrical Test & Engineering Services

The concept of engineering and electrical testing in the electronic component industry is not new, with modern practices being well documented for the past several decades. These practices are built on a core principle of understanding product design, application and characteristics prior to executing testing procedures. Along with a thorough and repeatable test plan, manufacturers have been able to steadily improve yield and product quality for their customers over the years. These established paradigms for engineering and electrical test work well for manufacturers, but fall short when applied to counterfeit mitigation programs, often due to the unique conditions posed by the gray market.
In response, component test labs have developed proprietary processes and methodology, usually with basic parameter tests such as “voltage in, voltage out” as the most frequently utilized option. At Classic, our imperative has been, and still is, to identify gaps, solve challenges and analyze relevancy of output data to remain effective in this high tech arms race against the counterfeiters. Through continuing innovation such as our custom software enabled “best of breed” test equipment, creation of customized repeatable test plans, and our in-house developed and fabricated test platform, we are committed to being a leader and a resource for our customers into the foreseeable future.

Integrated ATE &
“Best of Breed” Test Environment

When selecting our test platforms, it is critical to ensure interoperability when deploying an integrated “best of breed” environment which must be controlled. To enable software controls in a varied test environment, we start with a high bandwidth, modular bus technology (PXI-E) to cover transport and provide flexibility. From this scalable and flexible foundation, we have built out and continue to build out our test capabilities without bottlenecking and other problems typical within non-integrated environments.

Provided is a list of specification data of some of our core test systems:

  • PXI-E chassis with a high performance controller module capable of driving and interfacing with devices on all common media including GPIB, serial, LXI, USB, PXI and PXI-E.
  • An arbitrary waveform generator capable of high threshold signal generation even when factoring in all frequency (normal mode analog output frequency of 250MHz at 3dB with 2.0Vp amplitude), sampling (10 – 600 MS/s) and resolution (DAC @ 14bits, phase control @, 0.1° of waveform, time control @ 1ps, amplitude control @ 1mV and analog offset @ 1mV) combinations.
  • Ultra high precision measurement tools accurate down to the nano-volt (100nV @ <155mV), pico-ampere (100pA @ <300µA)  and micro-Ohm (10µΩ @ <100mV/1mA) range.
  • High precision LCR meter which can accurately measure a combination of low and high threshold characteristics such as low limit ESR readings (<15mΩ) at near maximum rated frequencies.

Classic R & D:
Custom Test Platforms

The gray market introduces unique challenges that can severely limit the effectiveness of electrical test. These challenges include:

  • Millions of potential product variations each of which requires unique test setup
  • Testing protocol creation lacking knowledge of product design or support circuitry
  • Decreasing test completion turn-around-time in days to weeks as opposed to months

In response, Classic’s R&D team has successfully designed and produced a patent pending hardware test platform to solve major “time to test” and automation problems caused by the wide variety of products. Our team has developed custom test code to drive programmable platforms, which enables us to overcome challenges posed by both increasing product complexity and lack of product design knowledge. These hardware platforms, in conjunction with in-house developed automation and control software, is just the start of innovative solutions yet to come.

Custom Software Development:
Advanced Testing Capabilities

The development and use of custom developed software is an absolute requirement to staying relevant, particularly in the rapidly escalating anti-counterfeit field. As a result, we have built our electrical test program around modern programmable software enabled platforms. These platforms have enabled us to custom develop in-house software for the purpose of test routine automation and control of test platforms to ensure delivery of rapid, reliable, and consistent results.

Additionally, software enabled platforms provide us with the high performance specifications necessary to perform a variety of advanced level tests today, while simultaneously giving us the flexibility to develop, evaluate and bring to market new cutting edge solutions.

Software is currently, and will continue to be the primary driver of innovation within our industry. Here are a few programming languages utilized in our test environment:

  • Verilog
  • VHDL
  • C++
  • Labview

Specialized OTB Tools & Resources

The use of software enabled programmable modular test platforms with high performance specifications gives us the ability to be nimble in our approach to test plan development and execution. However, it is the extensibility of the aforementioned platforms which enable us to engage external turn-key resources to create a truly synergistic environment.

Out of the box (OTB) turn-key resources such as CAN analyzers, JTAG boundary scan tools, and evaluation boards are readily integrated into our test environment to target specific parameters which eliminates the need for redundant effort.

Best Lab Practice:
Core Testing Methodology

Standards that define good laboratory practices are intended to ensure the reliability and repeatability of results produced. However, established standards such as ISO 17025 do not integrate well within subjective and highly variable environments typical to our industry. This is particularly true when applied to industry inspection methods such as those found within the IDEA 1010B standard.

Due to the limited value of established standards, SAE commissioned the AS6171 draft standard in 2010 to standardize and qualify subjective and highly variable test methods utilized for the purpose of detecting sub-standard and/or counterfeit product. Unfortunately as of 2014, the standard has yet to be released due to complications arising from the many challenges posed by the gray market industry.

At Classic, our engineers have analyzed and clearly identified both subjective and objective aspects of the testing process utilized by our industry. By understanding what factors and outputs we can control, we are able to confidently provide clearly defined and repeatable test plans to our customers which ensures accountability of our results.

This understanding also allows us to embrace the complex and investigative nature inherent to an anti-counterfeit test environment, which ultimately reinforces the critical value of working with our business partners to successfully mitigate risk through the exchange of reliable data.

Customer Engineering Assistance

All manufacturers are required to provide their end customers not only with the highest level of support ranging from pre-sales support to engineering services, but also custom solutions tailored to their customer requirements.

Similarly at Classic, we have identified the needs of our customers and have invested in the necessary resources that focus on providing advanced customer engineering services ranging from pre-sales such as design-ins to post-sales such as failure analysis.

When you buy from Classic, you are buying more than products, you are subscribing to the wealth of knowledge and technical expertise from a reliable business partner that you can trust will give you absolute peace of mind, enabling you to focus on the business programs that matter most to you.
