Overview of three prevention process and design requirements in PCB
In electronic processing, the essence of "Three Prevention" is to apply a protective film on the protected surface, and the protective effect is related to the coating method and coating process. The spraying part is the protection of PCB surface, and dip coating can protect components. Due to the fluidity of the coating and the non-uniformity of the substrate surface, the corresponding relationship between the coating times and the three prevention effects is determined.

Answer four possible questions in HDMI HD line connection
A friend thought of putting the HDMI video signal on the video receiving and display device, and found that the interface of the display device was VGA interface, which did not match. HDMI to VGA converter can solve this problem perfectly. One end adopts standard HDMI male port and the other end adopts VGA female port, which has strong compatibility and is more convenient to use.
