Introduction to PCB Fabrication and Common Issues Printed Circuit Board (PCB) fabrication is a complex process that involves multiple steps and requires precise control over various factors. Multilayer PCBs, in particular, pose additional challenges due to their intricate structure and the need for precise alignment between layers. In this article, we will discuss seven common […]
Introduction to PCB Soldermask Printed Circuit Boards (PCBs) are essential components in modern electronics, forming the backbone of countless devices we use every day. One crucial aspect of PCB manufacturing is the application of soldermask, a protective layer that covers the copper traces on the board. While soldermask comes in various colors, green has emerged […]
What is LPI Soldermask? LPI (Liquid Photo Imageable) soldermask is a type of protective coating applied to printed circuit boards (PCBs) to protect the copper traces from oxidation, prevent solder bridges, and provide electrical insulation. It is a photosensitive polymer that is applied as a liquid and then cured using UV light. LPI soldermask is […]
What is PCB Soldermask and Why Remove It? Soldermask, also known as solder resist or solder stop mask, is a thin lacquer-like layer of polymer applied to the copper traces of a printed circuit board (PCB). Its primary purpose is to prevent solder from bridging between conductors and creating short circuits during the soldering process. […]
Introduction to Soldermask Expansion Soldermask expansion, also known as soldermask clearance or solder resist clearance, is a crucial parameter in the design and manufacturing of printed circuit boards (PCBs). It refers to the additional space around the copper pads on a PCB, which is not covered by the soldermask layer. This expansion allows for proper […]
What is PCB Soldermask? PCB soldermask, also known as solder resist or solder mask, is a thin layer of polymer applied to the copper traces of a printed circuit board (PCB). Its primary purpose is to protect the copper traces from oxidation, prevent solder bridges from forming between closely spaced pads, and provide electrical insulation. […]
