Thank you for taking the trouble to perform the very experiment that I was planning to do for a few years! You have saved me a lot of time (and money) ! I particularly liked the fact that you took the time to combine the results on one screen.
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.
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!
I didn't think there would be enough people interested in contributing on my Patreon but there's been a couple of direct requests lately so I think I'll get that done for the start of 2019. Thank you for your donation!
@@voltlog Even if it wouldn't be that many, it'd likely pay for a few more rolls of tape if nothing else! Of course if setting it up is a huge hurdle, then it might take a while for it to pay back the time spent doing it...
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.
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.
Vou usá-lo na memória de vídeo de uma placa de vídeo, vou usar uma fita adesiva de 0,15 mm e ele fará a interface entre a memória e o calço de cobre. Eu não vi nenhum vídeo que usasse fita adesiva térmica, todos eles usaram pasta térmica ou almofada térmica. Acho que serei o primeiro a testar, filmar e postar.
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.
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.
just bought the thermal tape, marketed as lcd tv backlight double tape.. glad i didn't use it for cooling application, I use thermal glue instead. however, the stickiness quite good for non thermal related electronic application, compared to black 3m double tape.
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.
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.
An excellent video I would say! Short and on topic. You are saying that it is not scientific, however testing in your way is exactly one of the scientific approaches for proving the theory! Good job! Thanks :)
Would you describe how much force is needed to break out the heatsink from the component with thermal adhesive? Is it designed to never be replaced or it's possible to remove and reapply practically.
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.
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.
I dislike that you like the dislike button, but I still liked (the video that is). Thanks for the video, been trying to solve a heat problem and I think it's from using tape vs using paste.
I had opened my cable box because it was getting hot so I had bought thermal tape and I used it on the inside of the cable box. Now we I touch it the cable box fell cooler
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.
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.
@@voltlog If you mount a metal plate, preferably aluminum, on the tip of your temperature controlled soldering iron and set it to say 100 degrees Celsius, then stick 2-3 pieces of the thermal tape you bought, next to them same number and size of pieces of regular double-sided tape, hang equal weights on them and after heating up the soldering iron see which one stays stuck longer. And maybe try raising up the temperature until they start melting and get unstuck. They should hold up to 120-130 degrees maybe. Also make sure you degrease the surfaces before sticking the tape.
@@111chicane In minute applications, instead of using two layers, I use a razor to cut a small island in each patch and apply a corresponding amount of thermal paste (usually one drop); this way the tape holds the heatsink to whatever I'm applying it on, while the thermal paste transfers heat.
Just found this video 2 mins after ordering that blue tape from AliExpress. Oh well, it'll be used as normal double sided tape then. By the way I'm actually surprised how bad this tape is!!!
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.
I didn't realize they stopped making silver impregnated epoxy and I threw my tubes out because the plastic was dirty and I was being lazy. KICKING MYSELF
