Reel unloading and preserving practice
« on: February 02, 2024, 12:35:52 pm »
What is the current best practice for unloading a reel of SMD components and terminating the tape end? I am think specifically of minimising the loss of components and ease of re-deployment of the reel when next needed.

We recently received leftover parts from our contract manufacturer and I was dismayed at the lack of care for preservation of the parts in the tape. In some cases, the tape had been pulled back by a length, exposing the components, and was then closed up with masking tape. On examination I could see that some parts were lying upside-down or rotated. What can they do to preserve the packaging of the parts in the tape? And how should they best terminate the reel in preparation for future use?

When removing tape from the feeder, depending on the machine being used, you can end up losing anything between 10-50mm worth of components on the tape due to the feeder mechanism.
So having a few parts at the end of the tape fall off, rotate etc is normal.

For high-value items, care should be taken to minimise loss but don't expect that treatment to small value Rs and Cs.

On my old P&P machine, it was possible to not lose any components, but not worth the trouble for cheap passives like 0805 resistors.  On my newer machine, I can usually save all but a couple parts.  **BUT** there is a procedure for doing this.  You have to cut the cover tape at the right spot, carefully pull the component tape back and leave enough empty component tape to re-thread the feeder later.  Of course, a contract manufacturer won't spend the time to do this all neatly for you.
