The “Fatal Flaw” of Traditional Cleaning Methods As the “heart” of electronic devices, the stability of circuit boards directly affects the lifespan of the equipment. Traditional cleaning methods (such as alcohol wiping, water washing, and brush cleaning) are widely used but harbor hidden dangers: • Water washing: Easily leaves moisture that can cause short circuits … Read more
Let’s learn about the composition, design, process, workflow, and principles of component placement and routing for PCB circuit boards, along with some considerations for the later stages! Composition of PCB Circuit Boards 1. Lines and Planes: The lines serve as the conductive paths between components, and a large copper area is designed separately for grounding … Read more

The variable frequency air conditioner supports both online and offline read/write operations, requiring a programming socket to be inserted into the programmer. It can directly support reading and writing of .hex and .bin format files without manual conversion. When used with the RT809H programmer sold in home appliance repair forums, it supports both online and … Read more
The amplifier circuit can increase the output power of a signal. It obtains energy from the power supply to control the output signal waveform to be consistent with the input signal but with a larger amplitude. In this sense, the amplifier circuit can also be viewed as a controllable output power source used to achieve … Read more
