Companies seeking increased reliability and the minimization of field failures would do well to put their products through Environmental Stress Screening (ESS). As a series of tests that helps identify potential manufacturing flaws, having an environmental test chamber is critical for companies interested in weeding out short-lived units and distributing only the highest quality products for an enhanced customer experience.
The Shift in Industrial Trends Calls for Increased Product Reliability
With the past few decades’ shift in industrial trends, global competition has also increased. It has led to a higher demand for quality products, and consumers are now more conscious of how reliable their products are than they were in the past. The desire for products that can withstand the test of time and exceed consumer expectations has resulted in manufacturers making it their goal to achieve the perfect balance between the quality and cost of their products.
Improved Confidence that a Product will Endure Its Consumption Life
Thanks to the ESS, electronics manufacturers now have better product reliability testing methods. In fact, the mechanism of the test is simple: by utilizing temperature and vibration to accelerate product failure at weak points companies get insight as to how they can manufacture a better product. Conversely, by running a unit through an accelerated test, a company has proof that a product is free from manufacturing flaws.
Environmental Simulations Bring Failure Modes to Light
Why is thermal shock and cycling necessary, though? Temperature extremes can accelerate failures in products from various markets: from electronics and automobiles to military and aerospace applications. For instance, when low-quality cable connectors in a vehicle are exposed, the thermal shock could cause the material to expand and contract some parts of the connectors, making them fail or break down.
Reliability testing helps manufacturers identify unanticipated flaws in design and potential issues overlooked during production. Through different environmental simulations, it is a lot easier to bring specific failure modes in a product to light.
