Heat transfer compound is a 2 component mix, that is poured in at final assembly, to fill all the voids. Stays flexible and somewhat sticky, as it will slowly flow with heat to help ensure all the voids are filled. Similar to the thick thermal pads used in equipment, in that it ensures better heat transfer from hot areas to the case, though it is not as good as a proper aluminium heatsink, but as it is cheap, insulating, and also helps with minimising creepage on the board, it is used.
That’s actually brilliant, you get great products when the maker isn’t copying everyone else. Makes me want to see if I can make that with heat compound and plain silicon.
Nice teardown video. It gives us more insights before buying a product with our hard-earned money. Having said that, can you make a video on a tear-down of the TESSAN 100 or 140-watt travel adapter?
Great teardown. That strange silicone seems an acceptable means of transferring heat, since heat transferred to the opposite side of the charger when desoldering the PCBs. Any solution is better than no solution in my mind.
It's his original audio, in japanese. Which is also why some of the translation and voiceover seems repetitive I think, in japanese you don't have to repeat the subject as much, like how he keeps saying over and over "heat dissipation" and "silicon". It's kinda weird though I can't find where he uploads the originals, I kinda hate the voiceovers so I would rather just watch in japanese if possible.
It depends, but in this case it's likely because of cost reduction. For screws, you need screwholes which are like "tunnels". This increases the complexity of the injection mold a bit, but it might impact cost of it in some cases. Installing screws is also more expensive than just ultrasonic welding (again, it depends, but I think it's like that at least in this case).
Safety is the main reason. You don’t want kids opening them, but above all, you don’t want them breaking off while plugged into an outlet, even if the thing gets bumped. And since it makes no financial sense to repair such low-cost products, it’s cheaper to achieve the desired safety by using ultrasonic welding than fasteners.
Pink, highly heat conductive materials always make me wary - could there be beryllium compounds in the mixture, which can be extremely toxic to breathe?
I didn't expect your understanding of electronic products to be so shallow. The first cover you pry off is to cover the thermal paste filling hole. The reason for the heat generation is because power and efficiency have little to do with space. This is done simply because a 65W charger will have a thermal power consumption of up to 7.2W even if the conversion rate is as high as 90%. What's more, the high frequency of GaN chargers will reduce the conversion rate.
Nobody fixes small chargers, it’s not worth the time. And as far as repairs go, they’re among the more hazardous repairs to do, so you don’t want unqualified people doing it anyway. Anyway, finned heat sinks work great. But the point of GaN chargers is to make the chargers smaller, which is not something a finned heat sink achieves.
Franz go to cambridge online dictionary, there is a UK or US pronounciation. This video for solder uses UK pronounciation. Travel more worldwide , and learn more. As i recall britain speak english well before north america was even discovered 😂. This video original language is japanese, he is kind enough to offer english dubbed over version. What good is there for you to be so insulting to someone's video who is not a native UK/US English speaker .. even if there is a simple pronounciation mistake?
@@suryaprihadi2258 I am from the USA and say "sodder", but I believe it is not only people in the UK but maybe most English speaking countries that pronounce it "soLder". Definitely some (extremely well-educated) Canadians do. It is kind of amazing that people assume that their own pronunciation is uniquely correct.

Comprehensive video, very interesting and informative, thank you!
That pink stuff looks like it came off a lot easier than whatever was all over the board in a laptop power supply that I recently tried to clean.
that was probably thermal paste
Guess you need to tell us 5 more times why they used the silicon.
It's silicone for heat dissipation.
The Apple 5W USB iPhone charger cube has used an active clamp circuit for more than a decade. GaaN is the major innovation in these Anker units.

Tonight I am sure I will have dreams about pink silicone.
Wow, some in-depth knowledge gained 😮❤

Howw are you doing the translation?? This is so cool
I wonder if they pull a vacuum to help fill these with that pink stuff.
Is it just me or is there something playing in the background (someone else's voice)... great info and breakdown...

I don't understand why they make changes almost unable to disassemble

Do you have another channel? Didn’t you make a battery welder?
Jesus Christ. Seeing all that thermal goo in the thumbnail I thought you guys did teardown of a human brain 🧠 🤣🤣
How many farad long capacitor?
1:16 It's filled with silicone, not silicon.
Its thermal paste not silicone..
@@gemamoch1 Tell him, not me!
By the way, it's 👉IT'S,👈 not "its".

I don’t think anyone has made mass-market thermal compounds with BeO for decades. It’s used in exotic applications, but not mass-market stuff.
Why on earth would youtube keep recommending this to me? Do they owe the uploader money or something?
What is this voice on the background?
I wonder why it is filled with silicone
It's for heat dissipation

Teradownって何？
Very poor, anti repair design. It's better to use simple finned heat sinks.

This is the nightmare of new disposable electronics 🤮
And Tesla car battery packs.... SIGH
Will you please stop mispronousing 'solder'. It sounds so stupid.
