Normally, the electronic equipment is easily broken in autumn and winter, including the LED screen. As an expensive electronic product, how to maintain the LED screen during this time? Besides the normal maintenance, there are 3 aspects that need to be attention: static electricity, condensation, and low temperature. The static electricity is one of the Killers of LED screens. Not only will it reduce the service life of the screen, but also it will damage the electronics components and screen. No matter the indoor LED screen or outdoor LED screen, it is easy to produce static electricity and cause a…

The key to PCB EMC design is to minimize the reflow area and let the reflow path flow in the direction of the design. The most common return current problems come from cracks in the reference plane, changing the reference plane layer, and the signal flowing through the connector. Jumper capacitors or decoupling capacitors may solve some problems, but the overall impedance of capacitors, vias, pads, and wiring must be considered. This article will introduce EMC’s PCB design technology from three aspects: PCB layering strategy, layout skills and wiring rules. PCB layering strategy The thickness, via process and the number…
