Excellent video.I think this could explain voltage regulator failures I've had with some of my pt2399 boards in cb radios this last year.

Sad to see the thermal tape is not efficient but good to see thermal adhesive works okay. I've got both and I will now use them according to the heat transfer needed, so thank you for this comparison!

Thank you very much for such video. I've always wondered about real specs of this "thermal tape". Good comparison

Hi, Thermal Double Sided Adhesive Tape actually for application of bonding two surface that it will hold it adhesion at high temperature, for example 3M thermal DS tape for short term at 150C and long term at 60C. It's not really meant for heat transfer. However, it is more convenient to use than thermal glue as it does not require to wait for it to cured and not messy.

@class-A tow Because there is a proper thermal tape, like 3M 8810 tape thats actually have a proper thermal conductivity. However, as always Chinese will make a Chinesium grade of the proper thermal tape by using light blue color like what 3M do to their 8810 tape product.

I'm so glad I found this video. I was about to order some of that blue tape!!!

Thanks for this. I was getting ready to drill 3mm holes in my board and buy a push-pin solution for an embedded chip, now that I see silicone adhesive is almost as good as thermal paste, I'll just use that.

I am planning to use this on a CPU to cover entire area and except the die area where i intend to use liquid metal.. and make sure if this leaks it should leak on top of the tap instead of damaging small diode or capacitor.

Hi could you test adding thermal paste to thermal adhesive? Apparently its a reliable way to make it thermal adhesive easier to remove without harming its thermal transfer.

Hi, great video. I want to attacu small aluminium heatsinks to my GPU's memory module, what kind of material do you recommend? Thanks

There are these tiny, shiny, metal prongs that stick up and are located around the "M1 ,2 ,3, etc". I'm assuming those are memory pieces and need to have a pad and heatsinks. Is it ok if the pad/heatsink touches the metal prongs that are based around the M cubes, in addition to the M cubes themselves, or should I avoid contact with the surrounding Shiny metal prongs?

thanks very much

What do you think about using this thermal tape to mount heatsinks onto ICs or power FETs? The thermal conductivity is clearly not as good as thermal paste or silicon adhesive, but these solutions would be too messy on boards with lots of surface mount components.

Try repeating the test with kapton tape, there are various thicknesses of kapton tape intended to be used as TIM, either plain or with one side adhesive. I've successfully used general use self-adhesive kapton tape bought on ebay, though this may not be recommended for higher voltage insulation as it may have imperfections allowing punch-through.

Is thermal tape for heatsink better for transistor, mosfet in order cool down temperature fast?

The best method is, polished metal to metal contact, with thermal joint compound in between. screwed down tightly to the heat sink to squeeze out any extra compound and air bubbles.. Even anodizing of the heat sink, affects the contact area, hence the performance. Anything else, is a compromise that will deteriorate the heat transfer process. Convenience at the cost of performance.

You also have to consider thermal expansion. With some devices like GPU type chipsets, you can't have that type of rigid heatsink to device connection, you need to use a thermal silicone pad to allows for thermal expansion without cracking something.

Nice video

What about phase change tapes they have just come out! And claim up to 3 w/mk!

Would liked to of seen one test with no tape or compound just cooler direct on chip I'm sure it would have better results than with a tape or pad

i bought a few rolls of this optically same from aliexpress and thought about the same a few days ago. Thanks for testing, guess that thermal tape is not that great but still, it has excellent adhesive properties and it is cheap. i use it for different stuff but also thermal applications where it it not critical.

I would say the same about the tape, use it in places where the thermal transfer is not critical.

Would’ve been interesting to see if you’d have used thermal adhesive tape from a know brand with actual claims about thermal conductivity. I’ve got tape from Akasa and they list the thermal conductivity as 0.9 W/mK. This seems rather poor when you have thermal pads claiming 10 W/mK or even more. But hou have to keep in mind the ‘m’ (‘meters’) from ‘W/mK’. Thermal pads are thicker than thermal adhesive tape thus diminishing the advantage, greatly so if you use pads with 2 or 3mm thickness. I’m using the tape on MOSFETs which are vertically oriented so the heatsinks fall off if I’d use paste. Pads have somewhat stickiness, but still the tape performed better because of the more solid connection and thinness. Adhesive would perhaps work better, but is messy and doesn’t come off as clean as the tape does.

steel [JB weld epoxy]. non elect conductive and is better than any other thermal stuff!

This thermal tape does not have the best thermal conductivity, it's only high temperature resistant double-sided tape (the cheap one in the video). If you want to greatly improve the thermal conductivity, just stick it at both ends of the component as 2 strips and apply thermal paste between the strips. This way you only rely on the tape to hold the component or the heatsink in place and on the thermal paste for good thermal conductivity. It's usually applicable for components bigger in size, where you have big enough surface for both tape and paste. The thermal paste should be a very thin layer between the component and the heatsink, so the described method is no better than thermal glue but you don't have to wait for the glue to cure.

The video is very superficial, I'm sorry if it was informed but I did not see where, for example how thick the thermal adhesive tape ? What is her exact ad/model? There are dozens or hundreds selling on Eastern sites, each with its own specifications, some equal to the others and some not ... one cannot generalize as it was done.

No a good test. 30 degrees? Come on now, that's nothing. You didn't even test the bond strength. A power led runs at 70 degrees, bump it up to at least that and hold it for a few hours and then see how your normal tape fares, I bet it won't last long! These tapes typically advertise a temperature stability of 120 Degrees constant. The thermal tape should also preferably be firmly pressed when it's hot the first time to properly bond it. Thermal double-sided tape is the bottom-rung of thermal conductive solutions, but it's not just "regular double sided tape with a fancy name", it's designed to transfer heat AND to remain a relatively strong bond under high temperature and fluctuation, something that regular double sided tape is not going to do, not for long at least. If you can use thermal paste and screws/clamping hardware, or thermal adhesive, or even a sil-pad and screws/clamping, then you should, but thermal tape absolutely has it place. I use it all the time for sticking 1 to 10W leds onto heatsinks (actual heatsinks, or improvised ones like metal surfactes), or adding little heatsinks onto the top of ICs, or ....

Thermal adhesive tapes require not only to be pressed down for some time during curing at 50-60 degrees Celsius but also for its application to be absolutely voided of air bubbles, and in general it's the bottom of the barrel when it comes to thermal conductivity. So I, too, think the test wasn't fair to be honest.
