The precautions for the direction and shape of PCB printed wire include using short and simple wires, avoiding sharp bends or acute angles, maintaining equal distance between wires and pads, adjusting wire width based on pad spacing, reserving copper foil for common grounding wires, and providing a non-conductive production line on the PCB board to increase peeling strength of the pad.
Experienced engineers find PCB board design straightforward, but for new engineers, mastering circuit board design skills can be challenging, requiring clear processing level, careful copper foil placement, proper pad drawing, avoiding ground coexistence with pads and wires, ensuring pad length, and preventing pad overlap.

Single-sided PCB is a basic circuit board with wiring on only one side, suitable for simple electronic products and beginner designs, and commonly made with phenolic paper, epoxy fiberglass cloth, or composite substrates. It is cost-effective, but has design limitations and is mainly used in household and commercial machines. Its characteristics include standardized design, high wiring density, and mechanized production.
What is a Prepreg PCB? Prepreg is a part of untreated FR4. The FR4 is utilized in the PCB manufacturing process, where it performs the function of binding the etched cores together. It can also be useful in gluing the copper foil with the etched core. Thus, the prepreg in…
