pcb layout of the vehicle led lights constant current control module
2016
The present invention relates to a vehicle control lights LED PCB layout structure of a vehicle with the module LED signal constant current control. The present invention comprises a device layout, the control module when the SMT process with the use of the LED load the bottom surface of the circuit board is connected to the network design and the metal pad shield. The present invention has particular limitation on the layout of the device, the bottom surface of the pad using SMT technology and network LED circuit board connected to the load control module has limiting design space design and power ground through the metal shield reflux. Were based on this technology PCB layout can be better EMC performance, reduce the costs of trial and error. Limiting network design and the bottom surface of the metal pads used in conjunction with the shield such that the control module has a good performance particularly in radiated and conducted EMC aspects. It provides new methods and ideas through EMC experiment.
