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.
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 performing and even use this data early on to improve product development.
Process Capability Analysis means measuring and analyzing these variables to understand how they relate to product requirements and specifications. It helps identify which variables have the biggest impact on quality and which ones we need to control or eliminate.
Do you know the difference between quality and reliability? These two terms often get confused, but if you dig deeper, they actually mean different things. So how do you tell them apart?
(The following is just Workingbear’s personal opinion and doesn’t claim to be 100% accurate.)
Quality is a broad concept. What exactly is “high quality”? People often say that Japanese products are high-quality and well-loved. So in a general sense, quality refers to how well a product meets or exceeds people’s expectations or satisfaction compared to other similar products.
Personally, Workingbear think this process capability improvement flowchart is quite well-organized, so I cleaned it up a bit and decided to share it with everyone.
Please note: Before implementing Statistical Process Control (SPC), the process conditions must first be quantified. In other words, you need to find a way to turn the factors that affect product quality into measurable or countable data.
Process capability refers to the ability of a production process to consistently produce products that meet quality requirements under stable and fixed production conditions. To understand process capability, there are at least two key aspects we need to consider:
A manufacturing process’s capability is influenced by many factors, starting from product design, including materials, machines, equipment, methods, operator skills, inspection equipment, inspection methods, and the skill of the inspectors. Any changes in these factors can more or less affect process capability.
