Meaning
Surface mount technology processes use specialized joining techniques to maintain continuous operation of pick and place machines. Performing component reel splicing allows a new reel of components to be attached to the end of a nearly depleted one. This prevents the machine from stopping due to an empty feeder.
Mechanical Execution
Precise alignment of the sprocket holes ensures that the tape advances correctly through the feeder assembly. A technician uses a splicing tool to cut the tapes and join them with adhesive tape or brass shims. Successful component reel splicing requires the pitch of the components to remain perfectly consistent across the joint.
Standardized tools are necessary to ensure the joint thickness does not cause a jam in the feeder mechanism.
Feeder Efficiency
Production uptime increases when the machine does not require manual reloading for every reel change. Since component reel splicing happens while the machine is running, the line maintains its hourly output. Material waste is reduced because the leader tape of the new reel is not discarded.
Quality Risk
Improper joins can lead to mechanical jams or misaligned components during the placement phase. If component reel splicing is handled poorly, the feeder may fail to peel the cover tape back at the correct angle. Optical sensors on the placement head might detect the splice and skip the affected area.
Maintaining a clean splice area is necessary to prevent adhesive residue from contaminating the machine nozzles.
