Structural Classification Single-sided board: The … Read more
(1) Pre-define digital, analog, and DAA signal wiring areas on the PCB. (2) Separate digital and analog components and their respective traces as much as possible, placing them in their designated wiring areas. (3) Keep high-speed digital signal traces as short as possible. (4) Keep sensitive analog signal traces as short as possible. (5) Allocate … Read more
In the field of electronic engineering, printed circuit boards (PCBs) are indispensable components that carry the connections and communication between electronic components. A PCB is not a single-layer structure; it is composed of multiple layers, each with its specific functions and roles. Let’s discuss them below. 1. Mechanical Layer Definition: The mechanical layer represents the … Read more

1.First, we will place the components that have structural requirements, paying attention to the placement position of pin 1 of the connector according to the imported structure. 2.During layout, attention should be paid to the height restrictions in the structure. 3.If you want the layout to be aesthetically pleasing, generally position components based on their … Read more
Before the advent of PCBs, circuits were made through point-to-point wiring. This method had low reliability, as aging circuits could lead to wire breakage, resulting in open or short circuits at connection points. Wire winding technology was a significant advancement in circuit technology, enhancing the durability and replaceability of wires by winding small diameter wires … Read more
Although PCB manufacturing online has become very quick and cheap, with some manufacturers even offering free test board production, compared to making a test circuit board in “one minute“, sending out for board production still takes too long. For circuits that need testing, quick prototyping allows for rapid iteration to complete experimental circuits. The final … Read more
