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

What is 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

Understanding ORT: What It Is and How It Differs from REL (Reliability)
ORT stands for Ongoing Reliability Test, and sometimes it’s written as Ongoing Reliability Testing. ORT is a very important quality control measure in electronics manufacturing. Its purpose is to continuously monitor the reliability of products during mass production, so that … Continue reading

What is Environmental Stress Screening (ESS)?
Environmental Stress Screening (ESS) is a method used to apply certain environmental and operational stresses—such as power on/off cycles, bias voltage, pressure, thermal cycling, and vibration—to new or repaired products (usually electronics or components). The idea is to expose hidden … Continue reading
