World Class Reliability: Using Multiple Environment Overstress Tests to Make it Happen

Keki R. Bhote, Adi K. Bhote

 

Product excellence is no longer enough to sustain market dominance. Manufacturers in every industry have long known that there is simply no competitive advantage in mediocre offerings, so these days every assembly line is a model of consistency and a guarantor of well crafted products.

 

But what happens after your product goes out the door? Does its quality last? Is reliability built in, and can the product withstand years of use, misuse, abuse, and torturous conditions?

 

World Class Reliability gives you a proven methodology for replicating a lifetime of wear and tear in a tiny fraction of the time, under completely controlled conditions. This authoritative guide to best reliability practices shows you how to upgrade or replace your current reliability program with a comprehensive testing program known as Multiple Environment Overstress Testing, or MEOST.

Random Vibration & Shock Testing

Wayne Tustin

 

This minimal-mathematics minimal-theory text emphasizes test and measurement hardware and practice. Based in part upon Tustin’s lecture notes, it includes new material on digital techniques for spectrum analysis and for digital control of shakers for random, sine and shock testing.

 

The principle focus is on random vibration and MIL-STD-810F. The author shows the need for measurements and describes the most-used instruments for quantizing displacement, velocity, acceleration and force. He discusses instrument selection, usage and calibration. Most effective readouts, including spectrum analysis, are considered. He clarifies such electronic terminology as decibels and spectral density. To provide perspective, he briefly discusses relatively obsolete sinusoidal measurements and testing, also such peripheral subjects as torsional vibration, seismic simulation, acoustic (intense noise) as well as shock measurement and testing.

  • HALT Testing

  • img_test_halt_01Reliant Labs is the foremost industry leader in Highly Accelerated Life Testing (HALT). HALT is performed to uncover latent defects in product design, component selection and manufacturing that would not otherwise be found through conventional qualification methods. The process subjects the test sample to progressively higher stress levels, incorporating thermal dwells, rapid temperature transitions, vibration, and a combination of temperature and vibration to precipitate inherent defects. Moreover, HALT stresses the product to failure in order to ascertain design robustness and margin above its intended operation.img_aboutus_01

    Goals

    1. Margin discovery – operating & destruct limit.
    2. Uncover failure modes.
    3. Evaluate and improve product design.

     

    When the HALT is complete, we will have successfully gathered information about the true temperature and vibration characteristics of the product. The primary information collected will include temperature operating and destruct limits, vibration operating and destruct limits, and a detailed list of the failure modes found during HALT.  This information can be used to fix the weak links of the product’s design, as a benchmark to show improved reliability over time, and to develop a HASS screen for monitoring changes in the manufacturing process.

     

    HALT/HASS Summary

  • HASS & NTF Testing


  • img_test_ntf_01HASS Development

    Highly Accelerated Stress Screen Development (HASS) is a process to develop and define a production screen. HASS development verifies that the screen will find manufacturing flaws and not take significant life out of the product.

    HASS Development process defines and evaluates a specific HASS screen using the temperature and vibration operating limits determined during the HALT process. The production test setup is evaluated for thermal and vibration uniformity and repeatability by performing vibration and thermal characterization. The effectiveness of the HASS screen is then evaluated using a Proof of Screen process. This process verifies that the HASS screen is effective in finding manufacturing and process related flaws before production units are delivered to the customer. Once it is established that the HASS screen detects manufacturingand process related flaws using seeded or No Trouble Found (NTF) samples, the product is subjected to proof of life evaluation. The proof of life process evaluates the effects of the HASS screen on the end product. During proof of life evaluation, known good units are subjected to the HASS screen for a pre-determined number of runs to ensure significant life has not been removed from the unit.  For example, a typical product might be subjected to the HASS screen for 15 consecutive runs. Subjecting known good units to 15 runs of the HASS screen without failure confirms that no more than 1/15th of the product’s useful life has been removed after running production units through the HASS profile.

    An essential component of HASS development is root cause analysis and the identification and implementation of corrective action to ensure product integrity; thus increasing the product’s reliability and the robustness of design.

    Goals

    1. Define the HASS profile.
    2. Evaluate product fixture for vibration and thermal uniformity.
    3. Verify screen effectiveness.
    4. Perform product life valuation.

     


    img_test_haltscreen_01HASS Screening

    Highly Accelerated Stress Screening (HASS) is approximately a two to three hour screening process utilizing rapid thermal transitions and random vibration to expose process related variations in manufacturing. HASS is used to monitor outgoing quality and improve product reliability.

    Goals

    • Uncovers component supplier quality issues and revision changes.
    • Identify faults and implement corrective action to prevent future occurrences.
    • Uncovers degradation in Operating Limits caused by changes to software and firmware.
    • Perform HASS at chosen AQL levels to monitor process changes.
    • Uncover latent defects, workmanship issues, material discrepancies and vendor part modifications.
    • Maintain HASS results database and immediately report failures to contract
      manufacturer for root cause evaluation and corrective action implementation.

     

    A screening technique used to classify No Trouble Found (NTF) units as good or defective. Defective units are sent for failure analysis and corrective action is taken to prevent future occurrences. Passing units are returned after final test and are placed into inventory as sellable goods.

     

    NTF Verification Testing

    A screening technique used to classify No Trouble Found (NTF) units as good or defective. Defective units are sent for failure analysis and corrective action is taken to prevent future occurrences. Passing units are returned after final test and are placed into inventory as sellable goods.

  • Temperature & Humidity Testing

  • img_test_temp_01Temperature and Humidity testing evaluates your products vulnerability to elevated temperature and relative humidity levels. Common failure modes attributed to temperature and humidity are inadequate package seals, faulty encapsulations, increased growth of organic materials and contaminants, silver migration, and the effectiveness of conformal coatings.

    • ISTA 2A 2011
  • RDT Testing

  • Reliability Demonstration Testing (R.D.T.) is performed to verify that a product will meet an expected use in hours or MTBF. The process involves creating a test plan that specifies the sample size, acceleration factor, test duration, stress level, and confidence level. The test plan will then be implemented by monitoring functional units at an elevated temperature for a given time period until the MTBF goal is achieved.

    Failures in electronics equipment can generally be traced to long-term chemical interactions, or material fatigue caused by mechanical stress or temperature variations. A compromise of insulating properties and conductive properties in some materials may occur over time. Mathematical models will be used to predict how long reactions will take and how severe they will be as a function of environmental factors. The simplest model for electronic equipment is the Arrhenius equation.

    The Arrhenius equation was first proposed by the Dutch chemist J.H. van’t Hoff in 1884 and then interpreted in 1889 by the Swedish physical chemist Svante Arrhenius. It has its roots in the molecular motion within chemical reactions, where reaction rates increase with increasing temperature and decreasing activation energy.

    Since many failure modes depend on chemical reactions, the Arrhenius equation was adapted for use in reliability testing. The Arrhenius Model is applicable when elevated temperature is the accelerating stress and potential failures depend on molecular activity. The products under test are operated at a constant elevated temperature for a defined time period until the reliability test goal is met.

    The Arrhenius equation is shown below.

    Arrhenius-Equation

    If failures occur on the units under test, a Weibull distribution will be used to calculate the product reliability life assessment. Four failures must occur to perform the Weibull calculation.

    The Weibull objective of an accelerated life test is to accurately predict the BX life at the use stress level by using the failure data obtained from accelerated stress test. For example, the objective could be to accurately estimate the B10 life of a product, the time at which 10% of the units are expected to have failed. The accuracy is measure in terms of the width of the confidence bounds at a given confidence level. A result with narrow confidence bounds is more accurate than a result with wide confidence bounds (i.e. there is less uncertainty). Paraphrased from Reliasoft “Accelerated Life Test Plans”.

    Below is an example of a Weibull plot.  The blue dots are failures in time.

  • Power Supply Testing

  • Power Supply Characterization and Evaluation Services

    Given that power supplies are such a critical component in your systems design, ensuring power supply reliability is paramount to reducing field failures, building customer satisfaction, and lowering warranty cost.  Reliant Labs’ power supply evaluation services are available to expedite your design requirements, free up valuable engineering resources, and close the loop on your power conversion products.

    Pre-HALT Power Supply Test (PSP)

    This test subjects the power supply to specified environmental and operational conditions to evaluate the system prior to HALT testing.  The PSP establishes detailed performance data to be used as a benchmark when evaluating failures found during HALT.

    • Establishes a gold unit by validating power supply conformance to customer’s specification.
    • Reduce re-testing costs by assuring the product meets operational and functional specification prior to the initiation of HALT.
    • Generates a detailed power supply characterization for comparison against a customer’s or manufacturer’s functional specification.

    Specification Development and Design Review

    Reliant Labs creates functional and performance specifications, evaluates existing specifications, and provides independent power supply design reviews. Having a specification that does not match the required functionality and performance is costly in terms of field failures, customer dissatisfaction, redesign and re-testing.

    Power Supply HALT and HASS Testing

    By performing HALT we can help facilitate and evaluate the reliability of your power supply. By implementing HASS we can monitor outgoing product quality and detect manufacturing weaknesses before the power supplies are shipped to your customer. HALT and HASS can significantly reduce failure rates, lowers warranty costs, builds customer satisfaction and improves your bottom line.

    img_test_power_02 img_test_power_03 img_test_power_04
    Power Supply Comparison Testing

    A quick and effective way to select the right manufacturer for your power supply requirements. Side by side comparison testing rapidly evaluates different manufacturers’ varying input voltage and load conditions during the HALT process.

    Root Cause Failure Analysis

    Understanding failure mechanisms is critical to power supply reliability improvement and requires a thorough investigation into the failure. When the failure mechanism has been defined, a plan for redesign and follow up is generated.

    • Comprehensive inventory of test equipment including a 9kW AC power source, 12kW DC source, DC electronic loads, oscilloscope, power harmonics analyzer, etc.
    • Custom fixture design and fabrication.
    • Extensive inventory of connectors and cable harness fixturing.

  • IR Thermal Characterization

  • img_test_irtherm_01Thermal imaging fault isolation techniques employed by Reliant Labs provide a comprehensive thermal analysis on your power supply. Thermography quickly scans for potential hot spots and is a great tool for fault isolation during HALT and HASS testing.

    Thermal Characterization and Analysis Service

    As the electronics industry develops smaller, faster and higher power devices, thermal management becomes increasingly important. If thermal considerations are not managed carefully then high density, high performance designs will come at a cost.  Higher component and ambient temperatures are known to lower reliability.

    Placing devices closer together on smaller boards helps lower system size, cost and improves electrical performance. From a thermal perspective, however, raising power while reducing size can jeopardize system reliability.

    Thermographyimg_test_irtherm_02

    Thermography allows you to visualize the thermal behavior of printed circuit boards. Thermography provides simultaneous, non-contact measurement of temperature at tens of thousands of locations on the board.

    Thermal imaging hardware and software is able to convert self-emitted infrared radiation (IR) from electronic devices into accurate temperature measurements. Self-emitting radiation is a property of all objects above absolute zero and does not need to be induced externally.

    Thermal imaging fault isolation techniques employed by Reliant Labs provide a comprehensive thermal analysis on your product. Unlike thermocouples, IR Thermography scans over 1.2 million non-contact measurements per second on your PCB. Why make conclusions about your product using only a handful of thermocouples?

    Applications

    • Thermography quickly evaluates your product for hot spots.
    • Fault isolation before and after HALT and HASS testing.
    • Thermal characterization and engineering assessment.
    • Power on and sequence thermal analysis.
    • Verification of thermal design requirements.
    • Yield improvement through location of persistent defects.

  • MTBF Reliability Predictions

  • img_test_mtbf_01A reliability prediction is a tool to estimate the failure rate and therefore the Mean Time Between Failures (MTBF) of an electronic assembly in the environment in which it will be used. MTBF calculations are produced in the design phase to predict a product’s future reliability in the field.

    The value of reliability predictions are:

    • Provide evidence to prospective customers that the expected failure rate and MTBF of an electronic assembly will be acceptable to them.
    • Show the potential of a design of an electronic assembly to meet failure rate and MTBF goals, prior to being built.
    • Compare the expected failure rate of a new design of an electronic assembly, to the current or previous designs, to see if its field MTBF can be expected to improve or not.
    • Compare the expected failure rate of competing designs to determine which design should provide the lowest overall failure rate (highest MTBF) in the field.

    Reliant Labs performs parts count and parts stress prediction using Telecordia SR-332 or Mil Handbook 217. All that is required to receive a quote is a manufacturer’s bill of materials in Excel format.

  • HALT & HASS Fixturing

  • Reliant Labs designs and builds custom HALT and HASS fixtures. A well designed fixture ensures good vibration transmissibility and maximizes HASS product throughput. Working with your CAD files, our mechanical engineer will create 3-D models with pricing for evaluation. Once the design is finalized, our local machine shop can produce the finished product in 2 to 3 weeks.
