Introduction to Process Capability ─ How to Evaluate and Improve It
In earlier articles, we talked about three statistical indicators for process capability: Cp, Ck, and Cpk. But some people may still feel unclear about what these really mean. Let’s use normal distribution charts to explain them in a simpler way.

Understanding the Role and Responsibilities of Quality Engineers (QC/QA) in a Factory
Workingbear has always wanted to write an article about “Quality Engineers,” because in most factories, quality engineers, product/process engineers, and test engineers are often called the “three major engineering departments” in manufacturing. Of course, there are also production, machine maintenance, … Continue reading

The Role of a Manufacturing Testing Engineer in a Company
Here, the “Testing Engineer” we’re talking about is the one in a manufacturing plant responsible for product testing. We usually refer to the R&D engineers responsible for testing as EEs (Electronic Engineer). This role, along with the “Process/Product Engineer” we … Continue reading

What’s the Difference Between Electromigration (EM) and Electrochemical Migration (ECM)?
At first glance, Electromigration (EM) and Electrochemical Migration (ECM) might seem alike. In both cases, metal atoms or ions move from a high-voltage area to a low-voltage area, and both can lead to dendrite growth. But they’re actually very different … Continue reading

How to Perform Process Capability Analysis?
Process Capability refers to how well a process can produce quality products once it becomes stable. In real production, many variable factors can cause the process to fluctuate. By applying statistical methods, we can better understand how the process is … Continue reading
