A method for mounting an LED (light emitting diode) on a substrate, includes following steps. Firstly a substrate and an LED are provided. Secondly a surface mounter is provided, which includes a nozzle and a sensor in the nozzle. The nozzle includes a first electrode and a second electrode. Thirdly the nozzle is used to pick up the LED. The LED electrically connects with the first electrode and the second electrode of the nozzle to emit light towards the sensor, and the sensor detects optical characteristics of the light. Fourthly it is decided whether to mount the LED on the substrate or not according to the optical characteristics of the light detected by the sensor. An LED surface mounter which includes a vacuum nozzle and an optical sensor in the vacuum nozzle is also provided.
