What kind of adhesive is used to attach heatsinks when they are installed from the factory?? Or what do you use when you want to attach a heatsink to a device as far as glue?

Re: How to attach heatsink?
Artic Silver Thermal Epoxy remains flexible unlike some of the factory adhesives i've seen.
Artic Alumina adhesive looks appealing for this reason;

.Arctic Alumina Adhesive is a pure electrical
insulator, neither electrically conductive nor capacitive. -
Re: How to attach heatsink?
Ok, so is there any that allows removal without destroying the device? Just curious as if you use them on certain devices you may need to replace that device at some time in the future. I seemed to have read somewhere that a heat gun or blow dryer could be used to remove heatsinks so I wanted to find that particular adhesive

Re: How to attach heatsink?
if you mix in some arctic silver in with the thermal adhesive (i forget the ratio) then it can still be separatedComment

Re: How to attach heatsink?
Ahhhh, so thats the trick. I will hunt down the ratio now that I know the formula

Re: How to attach heatsink?
From what I quickly searched its 1 to 1 parts at minimum and most likely more of the AS5 (Arctic Silver 5) to insure removal without damage. The epoxy of course is 2 separate parts so 2 lines of equal length for the epoxy and 1 line of at least the same length or up to 1.5 of the thermal compound (AS5). Its an experiment waiting to happen.
On the other hand I found some thermal tape that is probably an easier option so I am all set. Thanks!

Re: How to attach heatsink?
If you think you will need to remove it I suggest you use frag tape instead and settle for the lower thermal transfer efficiency.
The types of thermal material you remove by heating the 'sink with a hairdryer/etc are only a permanent interface material that "can" leave the sink stuck to the part when they have cooled, but becomes more fluid when it heats up- this is a substitute for grease, not for semi-permanet cement-like action on a sink that doesn't have another mechanical attachment.Comment

TL;DR: Looking for as-close-to-genuine as possible iMac Thin Panel (2012-2019) Adhesive.
Long Rant: I run a tech shop that has a specialty in Macs. We've been doing upgrades and repairs on the thin panel iMacs as long as they've been out, and I've always had the issue of being unable to get something close to the OEM Adhesive for the Display Assembly, i.e. a 'two-part' adhesive, extremely thin but durable and can be cut easily with a thin wheel cutter. My replacement adhesive has always been essentially standard thin adhesive. For a long time, the biggest annoyance with this was having... -
Hello everyone,
I'm looking to upgrade the heatsink on the main processor of my TV's motherboard for better cooling performance.
The current heatsink is a square-shaped one (2.8cm x 2.8cn) with a basic design, and I believe a more efficient heatsink could help with thermal management and potentially extend the life of the TV.
I'd appreciate any advice on the best type of heatsink to use, specific product recommendations, and tips for installation.
If you've done a similar upgrade, I'd love to hear about your experience and any challenges you... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Macbook Pro A1502 Adaptor Shorted When Battery Attach
Unit works on Battery Mode
Unit works on Adaptor Mode
But When Adaptor and Battery both attach, the charger plug overheat so much, when using PSU it draw 3A when battery is attach
Checking battery connector when adaptor only attach, J7050 PPVBAT_G3H_CONN measures 12v- 0v- 12v cycle and the mosfet driving Q7155 pin 4 measures 5v then 12v cycle -
Dear forum members,
I am replacing the touchpad of Dell Inspiron 5520. I removed the old touchpad. It was glued to the palm rest. Now I should glue the new touchpad by some adhesive to the palmrest. but I do not know what kind of adhesive to use.
Once I used some wood adhesive. but the touchpad did not work when it was touched. It seems the adhesive blocked the sensing properties of the touchpad. So I removed the wood adhesive.
By inspecting the smell of the adhesive, I discovered that the adhesive of the old touchpad is not an ordinary adhesive such as super glue, or...
