When conducting performance‑degradation‑based reliability modeling and life prediction, to assess a product’s degradation‑induced failure, several key technical performance indicators that reflect the product’s health status are typically selected as characteristic parameters. If one or more of these characteristic parameters exceed a specified threshold (i.e., the failure threshold), the product is considered to have experienced degradation‑related failure. The selection of characteristic parameters must meet two criteria: (1) the performance metrics chosen must be precisely defined and amenable to monitoring; and (2) as the product undergoes operational or test exposure over time, these characteristic parameters should exhibit clear trend‑based changes, enabling objective…

Wow! This is what reliability testing is all about.
Reliability testing is an essential technical approach for evaluating and enhancing product reliability, encompassing the formulation of test plans, the development of test equipment, the recording of test procedures, and the establishment of failure‑analysis methodologies. Today, we will provide a detailed overview of the reliability‑testing framework and the most common types of reliability tests. The Purpose of Reliability Testing Reliability testing is conducted to analyze and assess the reliability of a product. By examining the test results, it is possible not only to determine the product’s reliability metrics but also to perform failure analysis, identify its weak points, and implement appropriate countermeasures, thereby improving overall product reliability.

Machine Vision Technology Series (I): An Overview of Machine Vision Technology
Machine vision is a rapidly developing branch of artificial intelligence.
Simply put, machine vision uses machines to replace the human eye for measurement and judgment.
A machine vision system captures images of the target object using machine vision devices—image acquisition units that come in two types: CMOS and CCD—and transmits these images to a dedicated image-processing system. The system then extracts morphological information about the target object based on pixel distribution, brightness, and other characteristics.

From the perspective of failure modes, product failures are classified into two types: sudden failures and degradation‑induced failures.
Product failure mechanisms can likewise be categorized as stress‑induced failures and wear‑out failures. Failures caused by stress‑induced mechanisms are typically sudden, such as glass breakage or elastic deformation; in contrast, failures arising from wear‑out mechanisms may manifest either as sudden failures or as gradual degradation.

[Technical Popularization] A Casual Discussion of the Bathtub Curve
When I first encountered the bathtub curve, I was immediately struck by its vivid and apt name—it’s truly spot-on.
Take a look at the diagram below: doesn’t it resemble the side view of a bathtub?

“Reliability” may seem like a difficult and obscure technical term. How can we grasp the essence of reliability and effectively carry out reliability‑related work? In my view, this can be approached from the following four perspectives.
This discussion does not delve into the specifics of theoretical study or research; rather, it focuses on understanding the fundamental theoretical principles and procedural frameworks essential for performing the job well.
