“Splicing” stands for the tape joint process while the mounter is operated. When there are a few LEDs left on the reel which is loaded on the mounter, some customers cut off and joint the edge of the tape to the next tape without detaching the feeder from the device. The splicing is to raise the machine utilization without bringing the device to a halt.
The splicing, however, may lead to the LED mounting failure; the LEDs may be tilted within the cavities due to the external stress applied to the carrier tape.
As below there are a few LEDs left on a reel and The edge of the tape is cut off and jointed to the next tape.
Note: Some mounting techniques for LEDs with a lens are described herein; however, they don’t fit in with all the mounters. Please select the optimal mounting techniques depending on the LED model and the mounter.
