Revolutionize Reliability Academy

Remember the promise of Design for Reliability (DfR) from the 1990s? It assured us that by incorporating DfR best practices, our designs would naturally become more reliable. Unfortunately, that hasn’t always been the case. But now, with the Revolutionizing Reliability Academy, you can finally fulfill that promise. This academy provides a clear, actionable methodology that guarantees your team will create highly robust products by default—every single time.

Imagine a world where your product development process is seamless and your designs are reliable right from the start. No more costly revisions, no more last-minute fixes. Picture your team confidently delivering products that exceed customer expectations and stand the test of time. With the Revolutionizing Reliability Academy, this vision can become your reality. You’ll transform how reliability is integrated into your designs, leading to fewer failures and higher customer satisfaction.

You’re not alone in this journey—many industry leaders have already seen the benefits. Companies like Amazon Robotics and Boston Scientific have used these same principles to stay ahead of the competition and deliver products that their customers trust. The methodology taught in the Revolutionizing Reliability Academy has been proven to work across various industries, ensuring that the promise of DfR is finally realized.

The time to act is now. Don’t let your team struggle with unreliable designs and missed opportunities any longer. Join the Revolutionizing Reliability Academy and start transforming your product development process today. Sign up now. This is your chance to finally achieve the reliability that was promised—don’t miss it.

ESS & HASS

Two of the most common acronyms used regarding manufacturing screening processes are ESS and HASS. ESS stands for “Environmental Stress Screening”?and HASS stands for “Highly Accelerated Stress Screening.” Here is the most fundamental differentiator: ESS uses the known product specification limits to test for defects, whereas HASS applies stresses that are beyond the product specifications but just under the operational limits. Product “specification limits,” used in ESS, are the maximum stress values to which the product is intended to be exposed in the field. Product “operational limits,” used in HASS, are the stress levels that,?when applied, inhibit the product from performing correctly (the beginning of the end!). Often, when these operational limit stresses are removed, the product returns to normal operation (a soft fail). The operational limits are not identified?in the product development process unless HALT (Highly Accelerated Life Testing) has been executed. HASS utilizes the information learned during HALT to target the identified failure modes with very high stress so that faults can be found quickly. Understanding the product limits from HALT also ensures that the product is not damaged nor has had too much life removed. This allows for a full screening of all products in?production. HASS stress levels are derived from HALT results based on multiple input factors. The general ranges of typical HASS stresses are as follows:

• Vibration is in the range of 35% to 65% of the vibration operational limit.
• Temperature is in the range of 65% to 95% of temperature limits.
• Stress durations are usually around 5 minutes per step.

An important final step in the HASS development process is “proof of screen”. Proof of screen ensures that that product life has not been consumed beyond established limits and that HALT-discovered quality defects are exposed.Terms

• Specification Stress – Stress level limits expected during field use.
• Operational Limit – Stress level at which product does not perform correctly. The product typically recovers when the stress is removed.
• Destruct Limit – Stress level at which product is disabled. The product does not recover when the stress is removed.
• HASS (Highly Accelerated Stress Screening) – Quality test based on HALT results that is done on 100% of manufactured product. Stresses go beyond the product specification but are less than the Operational Limit stress.
• HASA (Highly Accelerated Stress Audit) –?Quality test based on HALT results done on a selected percentage of manufactured product. Stresses go beyond product specification but are less than the Operational Limit stress.
• ESS (Environmental Stress Screening) – Quality test done on 100% of manufactured product. Stresses are less than the specification stress.
