Introduction to the Responsibilities and Roles of MPE (Manufacturing Process Engineers)

Introduction to the Responsibilities and Roles of MPE (Manufacturing Process Engineers)

Today, I want to introduce the responsibilities and role of MPE (Manufacturing Process Engineering). It’s a bit awkward because Workingbear’s own job is exactly this—MPE work. If you’ve read through this blog, you can probably guess that MPE’s responsibilities cover a huge range of tasks. You could say Workingbear knows a lot of different technologies from design to manufacturing, but isn’t necessarily a deep expert in every single one. How deep the expertise goes really depends on how much time, effort, and understanding each person invests.

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

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, and other departments in the factory.

However, since Workingbear has never officially worked in quality control, some of the opinions here may be biased or influenced by personal preference. Different viewpoints are welcome in the comments, but no name-calling, please.

The Role of a Manufacturing Testing Engineer in a Company

Testing-Engineer

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 mentioned earlier, is one of the must-have positions in a factory. Another key role is the “Quality Engineer.” Together, they form what’s often called the “iron triangle” of a factory’s engineering department.

What’s the Difference Between Electromigration (EM) and Electrochemical Migration (ECM)?

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 at their core.
