How to Design a Perfect PCB

1. Layout 10 Rules for Component Layout: 1. Follow the principle of “large first, small later, difficult first, easy later,” meaning important circuit units and core components should be laid out first. 2. The layout should refer to the schematic diagram, arranging major components based on the main signal flow direction of the board. 3. … Read more

002. HTTP Network Request Routing Configuration

002. HTTP Network Request Routing Configuration

A standard network interface uses a single-node route for a controller, but multiple methods can be provided through hot reloading. Generally, a controller uses four types of request routes: Create, Read, Update, and Delete (CRUD).1. Get: This method requests data from the server, allowing only data retrieval without writing to the server.2. Post: This method … Read more

PCB Design Checklist: Routing

PCB Design Checklist: Routing

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
