Q: How to Prevent Electronic Electrostatic Discharge (ESD)
A: Prevent Electronic Electrostatic Discharge (ESD) by being aware of the phenomenon that occurs when two objects with different electrical potentials come into contact and then separate, resulting in a sudden flow of electricity between them. This flow of electricity, known as a discharge, happens…
Q: What is Electrostatic Discharge (ESD)
A: Electrostatic discharge (ESD) is a sudden flow of electric current between two objects that have accumulated an imbalance of electric charge. This phenomenon occurs when there is a difference in electric potential (voltage) between the objects, causing a rapid transfer of electrons from one…
Q: What Causes a PCB Short Circuit
A: A PCB short circuit, also known as a “short,” occurs when two or more points on a printed circuit board (PCB) that are not supposed to be electrically connected become connected due to a low-resistance pathway. This unintended connection can lead to an abnormal…
Q: What Determines Solder Joint Strength
A: The solder joint strength is not determined by whether they are “leaded” or “non-leaded” but by factors such as the solder composition, joint design, and application method. Leaded solder typically contains a small amount of lead, which helps to lower the melting temperature and…
Q: Why use the Six Sigma Methodology
A: Six Sigma methodology is a data-driven approach organizations use to improve business processes and reduce defects or errors. Motorola first developed it in the 1980s, and many other companies have widely adopted it. The goal of Six Sigma is to minimize variation in processes…
