Smart Water-Saving Irrigation Control System Solution Background Overview With the increasing global water scarcity, especially in large-scale agricultural planting areas, traditional irrigation methods face issues such as water waste, cumbersome manual operations, and imprecise irrigation control. To address these pain points, we have helped our customers develop a wireless smart irrigation controller PCBA. This controller utilizes...

When designing a PCB, one of the critical decisions you’ll face is whether to use plated or unplated mounting holes. These holes are essential for securing the PCB to an enclosure or package, but the choice between plated and unplated holes depends on your design requirements, grounding needs, and mechanical considerations. Let’s explore the differences, advantages, and best...
