The PCB circuit board is a support component of components and devices in electronic products.Even schematic diagram is correct, but uncorrected PCB layout design will also effect the reliability of electronic products. In the design of printed circuit boards, attention should be paid to the correct method, to comply with the
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,
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
The wiring switching power supply contains high frequency signals
Any printed circuit on the PCB can play the role of the antenna,the length and width of the printed line will affect its impedance and inductance, thus affecting the frequency response.Even the printed lines through the DC signal are coupled from the
Seven steps of LED switching power supply PCB circuit board design.
In the switching power supply design, if the PCB board design is incorrect will lead to too much electromagnetic interference.There are seven PCB design steps will great stable power supply.Through the various steps in the need to pay attention to
