With the orientation of marketing, the base of quality, and the assurance of efficiency, our mission is to provide top-ranking products and services for customers and continuously improve customers’ satisfaction.

PCB design is the first step in PCB industry. Before carrying out the production, PCB design drawing should be checked after the system layout is completed in order to make sure that it’s reasonable and if it can achieve the optimal effect. Here is a manual on how to examine the placement in PCB Design for the beginners in the field of PCB.
 

1. Ensure that the PCB design can guarantee the reliable cabling circuit performance. Make an integral comprehending and planning with the direction of the signal, power and ground wire.
 

2. Make sure that the measurement of the PCB is consistent with the processing drawing, whether it can meet the requirements of PCB manufacturing process or whether there is any action tag. Some of the layout and wiring PCB design seem to be perfect, but the precise positioning of the positioning connector is neglected which may leading to the failure of the connecting between the circuit and other circuits.
 

3. Ensure that there is no two-dimensional or three-dimensional conflict among the components. Take note of the actual device size, especially the height of the device. The height should not exceed 3mm while welding of the components that are free of layout.
 

4. The components placement should be completed with proper density and order. Beside the direction type of signal, the overall density of the components placement should also be taken into account.
 

5. Make sure that those components that will be changed frequently can be easily replaced and inserted into the device conveniently.

6. Ensure that the adjustable components are easy to be adjusted.
 

7. Ensure that the distance between the thermal components and the heating element between is appropriate.
 

8. Take care of the cooling of the components and circuit boards. Some devices should be equipped with heat sink or fan to make sure that the air flow is smooth.
 

9. The signal routing should be smooth with the shortest interconnection.

10. The plugs and sockets should be consistent with the mechanical design.
 

11.  The problem of line interference should be taken into consideration.
 

12. Take note of the mechanical strength and performance of the circuit board.
 

13. Finally, if the PCB design is perfect in appearance, it’s better.

A good PCB design is the precondition of a successful PCB board. So the final examination of the placement in PCB design is very important.
