1. Layout 10 Rules for Component Layout: 1. Follow the principle of “large first, small later; difficult first, easy later,” meaning that important circuit units and core components should be prioritized in layout. 2. The layout should refer to the schematic diagram, arranging major components according to the main signal flow direction of the board. … Read more
Route according to the 50-ohm impedance line width, try to route from the center of the pad, keeping the lines straight and preferably on the top layer. When a bend is necessary, make it at a 45-degree angle or as an arc, preferably bending near capacitors or resistors. If routing meets the matching requirements of … Read more
