Hello, eveyone.
I want to share some PCB layout rules that i summarized and collected.

1. Heating components The arrangement of printed wires should be as short as possible, especially in high frequency circuits. cannot be in close proximity to the wire and the heating-sensitive components; the high-heating components should be evenly distributed.
2. The arrangement of printed wires should be as short as possible, especially in high frequency circuits.
3. In order to make sure the electrical property, the element shall be located on the gridlines and in alignment, to keep it natty and artistic.
4. Metal shell components and metal parts (shield boxes, etc.) can not touch other components, can not be close to the printed lines, pads, the spacing should be greater than 2mm.
5. Polarized componentsshould be as consistent as possible in the direction marked by the polarity on the same board.
6. When the circuit board is larger than 200MM x 150MM, the mechanical strength of the circuit board should be considered.
7. The patch is unilaterally aligned, the characters are in the same direction, and the package direction is consistent
