In the manufacturing of printed circuit boards (PCBs), it is common to encounter solder bridging issues, where unexpected solder connections occur between adjacent pads. This is mainly due to improper pad setup, and if not addressed promptly, it can lead to circuit shorts, affecting normal functionality. So how do you choose pads? Perhaps you can … Read more
Like many other great inventions in history, the printed circuit board (PCB) as we know it today is built on the foundation of historical advancements. In our little corner of the world, we can trace the history of PCBs back over 130 years, when the great industrial machines of the world were just beginning to … Read more

To properly place SMT components, the PCB must remain completely flat. For accurate placement, the pick-and-place machine must release the SMT components at the same height above the circuit board for all components. If the PCB is warped, meaning it is not flat, the machine cannot maintain a constant height when placing components on the … Read more
Purpose This article introduces the implementation principles of the ROS Robot Operating System, analyzing how ROS code is implemented from the lowest level. 1. Serialization Serializing the content of communication (i.e., messages) is the foundation of communication, so we first study serialization. Although I have been engaged in robotics learning and research for a long … Read more
When PCBA designers design circuit boards, they often leave process edges. Do you know why this is done? What are the benefits of designing process edges?Today, I will explain why PCBA needs to design process edges.The PCBA process edge, also known as the working edge, is a long strip of blank board edge set aside … Read more
