Question about tape & reel

to

o

something like this?:

ice-tapes

-Lasse

That is for splicing two reels together. I need the stuff that peels of easy to let you leave the leader clean for a component feeder. Thanks for trying. :)

How about a rubber band?

Cheers

They aren't anti-static, and have a very short life in Florida. They either harden & crumble or turn ito a sticky mess. :(

Or buy the tape and cut an 8mm long piece. Then the tape 'width' becomes your 'cut length'.

So, 8mm long segments of any ESD safe tape will do. Even 7mm.

Get the two inch wide stuff, and then your 2 inch piece can have a small release tab folded onto the end of it.

Get the clear stuff, and you can encapsulate a small printed ID tag inside the tab.

Even the PVC ones? Latex, that I believe.

Cheers

I've never had any last over a year, so I stopped buying them. I have no idea on what the few that I run across are made of, but most are deteriorating when I get them.

How about this stuff?

(other widths available, of course) or go fancy (and overkill for reel-ends) with a low-static Kapton like

Probably 3M and others. Maybe you could call one of the places that both sells cover tape and does reeling as a service?

Eg.

I've had trouble buying specialized tapes in relatively small quantities.. usually they want a minimum of one roll.. but what they count as a roll is the original 36" wide roll, cut to whatever width you want. At, say, 5mm wide you'd get almost 200 rolls out of the mother roll, which might be more than you need atm.

I may have to resort to that, but not while I don't feel well enough to deal with a phone.

It's no wonder that some partial reels I have arrived with cheap cellophane tape across the ouside of the reel. You would think that it would be readily availible from anyone that sells a lot of tape & reel components.

You would think places selling reels, carrier tape & cover tape would sell the other type.

Why worry about ESD for taping the end of a reel of resistors?

Because I may try to sell off some of the full reels. I don't have a lot of need for multiple reels of the same values of .1 and .01% resistors

I also have some reels of transistors that I am going to use for some projects.

How do your production people handle partial reels?

We just stick a bit of tape on the end to keep them together, usually the tape that the reel came with. But the resistors are tucked inside the reel, so I can't see the type of tape mattering.

I see some partial reels in pink zip lock bags and others with loose ends. How many types of SMD resistors do you carry in inventory?

Types? Lots. 2512, 1206, 0805, 0603, a few 0402s in 1% thickfilm. A few legacy 5% parts, although all new thickfilm resistors are spec'd as 1%. Then we have thinfilms down to 0.05% and 10 PPM. And some carbon/metal axials, power resistors, networks, shunts, weird stuff. We have over 1200 resistor stock numbers, maybe a million pieces.

We try to avoid adding more resistors to stock, but that's mathematically tricky some times.

The color dots thing was my idea. It reduces wrong-bin errors a lot.

Nice. Where did you get those cardboard holders from ?

The big reels (eg. for TO262) are a pita.

I meant the total number of different resistors. We had to deal with over 4,000 in the Microdyne inventory going back to their oldest products. We also had engineering kits for a lot of families, which was a PITA. We would need an odd value for a S.I.T. and have to beg engineering for one. If they had remembered to reorder what they had used up. The guy in charge of their inventory thought that he should wait till they had between 50 & 100 values that needed to be ordered. They would pay more for 100 in a zip lock bag than we paid for entire reels. :(

I used them 30+ years ago to color code repairs on CATV equipment. Three colors for electrical, mechanical problems and abuse. I could write up to 13 lines of notes on a 3/4" Avery dot. The colors work OK, as long as you don't end up with several new parts in the middle of the current layout, and have to reuse a color too soon. :)

Graduate to two dots!

All I could find were white the last time I checked the local office supply stores.
