High quality PCB common layout principles
1.Component Arrangement Rules
1). Under normal conditions, all components should be placed on the same side of the printed circuit, only in the top layer of the element too dense, can be some highly limited and small heat, such as SMD resistors, SMD capacitors, SMD IC on the bottom.
1.How to select PCB material?
For the selection of PCB plate, must meet the design requirements and scalability and cost of the middle to achieve a balance point. Design requirements include two parts of the electrical and institutional components. This material problem is more important when designing a very high speed PCB board (greater than GHz frequencies).
