In PCB design, consider signal quality control factors, the general principles of PCB layer stack up should be follow below:
The second planes adjacent to the component surfaceis ground plane, providing device shielding layer and referenceplane.
All signal layers are adjacent to the ground plane as much as possible to ensure
What are the basic principles of PCB design for whole board layout? How to optimize and analyze?
Reasonable layout directly affects the life of the product, stability, EMC (electromagnetic compatibility), must from the overall layout, circuit board wiring condition and PCB manufacturing, mechanical structure, heat dissipation, EMI (electromagnetic interference), integrated and reliability,
When we design a project, we care more about layout and wiring, and often ignore the additional PCB manufacturing costs in the design. Here are some of the factors that affect PCB prices in the design and avoid increasing costs to customers.
PCB Layers number:layers good for layout, but the price
PCB (Printed Circuit Board) is an important electronic components, it’s base board of electronic components and carrier of electrical connections. it is called "printed" circuit board because it is made using printing technology.
Double-layer circuit board is layout wiring on both sides, but to use the two sides of the wire, must have appropriate circuit connection between
New PCB designer always confuse how to build the min trace width and space for heavy copper PCB. Now PCB manufacturer engineer tell you how to do?
The min. trace width/space at inner layer :
The min. trace width/space at outer layer:
