Is it possible not to place silkscreen position numbers on a PCB? The silkscreen position number is mainly for convenience during manual soldering or prototype debugging stages, as it visually indicates the component positions, facilitating assembly, maintenance, and testing, primarily used in the prototype phase. It is indeed possible to manage without position numbers when … Read more
1. What is a Reference Point (Mark Point)? Mark point is also known as a reference point or optical positioning point, which is used as a positioning point by pick-and-place machines. Since PCBs provide a common measurable point for all steps in the assembly process during mass production, every device used in assembly can accurately … Read more
The eight major process systems of PCBA (Printed Circuit Board Assembly) cover the entire process from component placement to finished product testing and packaging, detailed as follows: 1. SMT (Surface Mount Technology) Process Process: Solder paste printing → Component placement → Reflow soldering Function: Precisely place surface mount devices (SMD) onto PCB pads and form … Read more
In microcontroller development, we often need to hand over the designed PCB files to the factory for production. Recently, one of our engineers encountered a troubling issue, as the PCB board lacked Mark points, resulting in deductions from the SMT factory. Today, we will discuss this topic: how important are Mark points in SMT processing? … Read more
For the layout of SMT components with small pin pitches such as QFP, QFN, and SOP, we sometimes encounter situations where adjacent pins of these components need to be interconnected. It has been observed that many designers, in an effort to save time, directly route the connection between the pads, effectively shorting the pins together. … Read more
