Understanding Soldermask and CTI Soldermask, also known as solder resist, 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 from oxidation and prevent Solder Bridges from forming between closely spaced pads during the soldering Read more…
What is Soldermask Made Of? Soldermask is typically made of a photosensitive polymer that is applied to the PCB surface in liquid form. The most common types of soldermask are: Liquid Photoimageable Soldermask (LPISM): This is the most widely used type of soldermask. It is applied as a liquid and Read more…
What is a Gerber Viewer? A Gerber viewer is a software tool used to view and inspect Gerber files, which contain the design data needed to manufacture printed circuit boards (PCBs). Gerber files use the RS-274X format to describe the copper layers, solder mask, legend, and drill holes required to Read more…
What is a Drone Board? A drone board, also known as a flight controller, is the central processing unit of a drone. It is responsible for controlling the drone’s movements, managing its sensors, and communicating with the remote control. The drone board receives input from various sensors, such as accelerometers, Read more…
Introduction to PCB Surface Finishes Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for mounting and interconnecting electronic components. The surface finish of a PCB plays a crucial role in its performance, reliability, and manufacturability. Two popular surface finish options are Hot Air Solder Leveling Read more…
