Double Sided Tape

[DanF]

I find myself needing double sided tape every now and then (especially with laptops and tablets). Most of the time due to some broken plastic holders and similar situations.

Problem is the one I'm using doesn't seem to be as strong as I need it to be. Are there any specific features / standards / metrics to look for when buying?

Thanks

Red 3m tape.

Red 3M is very strong, often used for security on retail displays. You can pick it up at Staples here in Canada.

Sometimes I use Silicone for adhesive situations, depending on the need, as tape works well for large objects, but smaller items it doesn't always work well for. I always use non corrosive silicone.

I use Tesa 61395. Its what is rumored to be the original Apple iPad adhesive. I've used both the red and black Tesa adhesives, and while I'd consider the 4965 (red) to be a reliable adhesive for most cases, I'd consider the 61395 (black) to be better in almost all cases. The difference in your application may be negligible though. But since they can be had for the same price, I don't see myself ever ordering the red again.

Never heard of the 3M Red tape though. Isn't that like mounting tape? Probably a bit too thick for doing tablets, no?

Obviously thickness is the key. The stuff I've seen on smart devices and laptops are in the 3-5 mil range, not including the release liner. Though some have been thicker. The MBP screens have a thicker one on some places. Looks like maybe 15 mils or so of butyl based adhesive. Not a double faced tape with substrate.

I'm using this currently and its been great so far. It's thin stuff and only 5mm wide so it is suitable for tablet/digitizer glass repairs. Super sticky too:

Search eBay for 3m red tape and buy every width.

Thanks all, really helpful.

Does this seem legit: AliExpress ... Seems to be really thick from the picture.

That does look really thick, which is what I expected from NviGates comment about it being used in retail displays. Not suitable for things like iPad, and probably going to cause a gap in laptop lid bezels and such that may lead to customers complaining.

It's probably great for general purposes that the public at large would need, but for electronics you need something designed to be thinner and with more specific use cases in mind. That's why I like the Tesa stuff. You could also try the 3M 300lse adhesive which is what I used before switching, though I don't see why you would get that unless you couldn't get the Tesa.
