For you with pick-n-place machines.
The cover tape needs torn off from the component strip to expose the next component to be placed.
If the cover tape is too short, you either have to waste some components by pulling the cover tape off long enough, or simply extend the cover tape and you don't waste components.
There are such tools available to tape the extension cover tape to the reel's cover tape, but are expensive (in my opinion) and is a stupid process, looks very fumbly.

There is a very easy way to join the cover tape.
I use a bag sealer, inexpensive and easy to use.

There is one small trick or the cover tapes won't join.
You have to use the upper side of the reel tape on the extension tape's upper side.
The bottoms have glue and often fine paper that tears off, and then plastics won't join.
You have to place the clean plastic on the clean plastic.

If you zoom in you can see the joints in the tape. I do two joints and cut any excess off.  As strong as the tape.

I have one of these.  I only run it at 75% speed otherwise it goes (feels) out of control fast.

It uses cameras to align view the board position and the components orientation and shows it on the screen too.
I place large chips like the ESP's in the front squares and it picks it up from there.  By telling the machine how large the chips are, it adjusts the vacuum to pick the chip up and I slow the placement down or it will move too fast and drop the chip.  The vacuum used is amazingly efficient, the pump runs every now and then for a short duration.

There are video's on the tube if you want to see it work.  ZB3245TSS, the baby model.
https://youtu.be/FhRlepCc_C0  I suspect the machine is set at about 50% speed and he places the ESP's at the end.  He uses one small nozzle and one large.
Mine picks up two components at a time and place them, like this one https://youtu.be/iQwhKeQKhRU.
You can tell it which nozzle to use or not for which components.

The Chinese even now after so long enquire once in a while that all is well.  Excellent service.

I named the machine Rina because Rina assembles the boards ;)
Besides feeding me coffee.
