SMT stencil preparation: tips & tricks, and design software
Why do we talk about printing the solder paste and the importance of SMT (surface mount technology) stencil design? Once the PCB layout is finished, the stencil may be the last way we can enhance PCB assembly quality. But currently, stencil design work is typically knowledge-driven, relying on human processes, and can easily cause issues…
Impedance control issues in PCB manufacturing
Impedance control requirements often accompany the fabrication of complex multilayer printed circuit boards. Understanding the peculiarities of meeting these requirements helps not only to reduce the time for launching boards into production, but also contributes to obtaining a better result. Impedance control at the PCB factory can be roughly divided into several steps: Selection of…
How to make sure that the PCB impedances are correct even after routing changes?
Do you agree that the work of a PCB designer is not always noticeable to others, but very important? The boards you make are built into the latest equipment, often into equipment for responsible use, on which the comfort, health, and sometimes life of people depend. But since these boards are hidden inside the body…
