I appreciate the ambient noise and birds

The wielding of the precision tools, the melting flux, the cleaning and application.
“Hardware surgeons” on their own operating tables 🔥
🥰
You have to be talented, follow the rules and know what you're doing.
And I always thought those connections were part of the chip, when in actual fact they are on the board, thank you I have learnt something new today.
🥰
It depends on the package of the integrated circuit. "Older", SOIC, TSSOP or TQFP packages have legs. Newer QFN and BGA packages don't. They are smaller but very hard to work with.
The solder blob under the chip was too much
Soldering job looks excellent! But your tip is running way to hot which is why it's going blue. I'd recommend sticking to 360c unless you really need better performance for you job.
How do I know? I made the same mistake haha.
You are correct, that soldering iron was bad, i replaced it
Dear,
1. Which Flux you used?
2. Furthermore, Temp and Air settings.
Your Humble response would be of great help to me
At what temperature was the hot air gun set to?
350c
Pouco fluxo, bote mais 😂
🤣🤣🤣
Очень мало флюса, надо больше! а вообще надо всю плату во флюсе держать так лучше паяется 😂.
🤣🤣🤣🤣🤣
Я такие микрухи вообще без флюса выпаивал, не понимал зачем он вообще нужен при выпайке. А потом понял: флюс плавится и более равномерно распределяет тепло по плате и микросхеме, нет большого перепада температур между платой, ногами микрухи и корпусом. Это я к тому, что большой расход флюса, на мой взгляд, оправдан.
@@AClockworkParrot А как же основное предназначение флюса, а именно удаление оксидной пленки? Или вы даже микросхемки с зелеными контактами выпаиваете без флюса?)
@@AClockworkParrotЧто за флюс такой? Как называется?
Depois que comecei usar o fluxo aprendi a retirar sem estragar componentes.
🥰
Way too much solder on the center pad. It will ooze out and short out one of the leads around the perimeter.
I hope not
Yes, top much solder on the pad !!! The vídeo was cut...
Was this clearish paste some type of flux? Was that paste heated with a heat gun? How was the solder between the pins and PCB removed to get that chip off?
Please can you indicate us what is the ideal Temperatur to desolving
Que satisfacción 😅💯🤯
🥰 🥰
Надо было ведро вылить 😂
🤣
Really cool man. Not sure i have hands for that lol
The tip of your soldier is so beautiful lol is colorful
Simply put IMPRESSIVE.
You just discover warm water

A vasão de ar é baixa? Quanto tempo de aquecimento?

Cool and clean

Nicely done.
🥰
Very nice work❤
Thank you 😊

Exceso de estaño y exceso de flux
😁😁😁😁
Nice video can you mention what is the temperature and time?
Did you used board preheating here? Found quite hard to replace QFNs without preheating at bottom on thick PCBs only with hot air.
There is never too much flux :)
I preheat always for few minutes before i focus the heat on one spot
@@f1lab535 i had a no lead mosfet near electrolytic caps that are smd so i cant remove them without fear of damage, how would you keep them from popping?
I get flux at the end. What did you use at start to release
What liquid you have used for desolder. The components
Bga soldering flux
Wow its will useful 😊
🥰
A video of "how" whiteout instructions, brilliant 😢
😁
What are you wipeing it with?
Saya juga tukang tapi heran lihatnya Kren saya blum punya Alat untuk buka IC kaki kecil😂
🌷😁🌹
What all are you using in-between the main Soder sorry if miss spelled? Heat gun with what to release? Copper/silver strip to lay down?

Hi,what are you using to remove that IC so easily. I normally use a hot air gun but it is not that easy.it takes time to remove.
The video seems to be edited.
What is the temperature that you use to remove and what's the temperature to reinstall that you use?
350c ---300c
@@f1lab535 thank you.
bonjour, cest quoi la marque du flux que vous utiliser ? peut on s en procuré, Il a l'air bien efficace merci
Looks like way too much solder on the thermal pad
😁
what did he do? "yes"
How does all the pins are connected to the board? Even if 1 pin is missed, the IC is useless 😮
Yes 🥰 🥰 🌹🌹🌹
Procedure with things using details provide?
Hi, which flux and soldering paste are you used ?
Bga soldering flux, and low melt solder Www.c8ke.com/GRTSHOP
@@f1lab535 Malwarebytes says website blocked due to phishing.
What is the recommended temp??
Make it look so easy these damn high quality motherboards and GPUs dont want to melt worth a squat *kicks a pebble*
It needs to be accurate and away from error ❤🚫
🥰
Blue colour on the soldering tip means the temperature is to high....
You are using to much flux and You put it on chip. Why? There is no pins!!! You should to put it on the chips bottom.
I dont remember the temperature but usually i dont go above 400c, and use alot of flux to avoid the pcb being burned, so i always clean the used flux
Are you using a preheater? Because I can't unsolder.
I pre heat the board with hot air for about 3-5 minutes slowly before focusing the heat on one spot
@@f1lab535 It's just, I have tried to unsolder the EC on my customer's laptop and have accidentally damaged the contact plates... Now they're trying to send a hitman after me...
Oui ! c'est bien ! mais les composants électroniques vont TRANSPIRER !! voilà voilà
🌷😁🌹
What is that black and yellow in the lower right side?
I think you are taking about the small yellow and black dots, they are viers that penetrate the pcb and go to another layer

Sir what kind of light you have installed on your desk? Do you have any link to purchase?
I will send you the link tomorrow

Wayyyy too much solder on the slug, next cut fixed it

what your flux? i like

What temperature is used sir?

super 👌

What is that white glue

Enough solder left just to put another one on with flux paste
😁
так себе, работаю на производстве. за 20 секунд поменяю такой. и будет не отличить менялся он или нет.
🥰🥰🥰🥰
Why did he applied it on the chip, but the legs?
Needed it melted?
It flows with heat
@@f1lab535 Thanks, bro!
Никогда так не делайте
😁🙏
what is the name of that gel like material? p
ls
Bga soldering flux
The solder in the middle of the chip is used as a heat sink, dont solder wick it
Okok
what set temperature in hot air ?
350-400
Why you don't show what's the problem with it? How do you know if it's good? Or because you're just taking it out. But you're not the same and this good. Is boys bad like why you've finally default on it before honey on the car
Flux name and Amazon buying link give me please
Www.c8ke.com/GRTSHOP you can find the flux i use at the bottom of the list.
appreciate if you could tell me the best temperature for that
You need to practice to find the best temperatures, its different from board to board, its also about timing, you can use 600c and must be very quick and precise, or you can go gently with 350c and the time will change, but like i said some boards will not resist high temperatures, and preheating is a must always
Thank @@f1lab535 for the kind advice.
@@f1lab535❤
what temperatures?
350c
Okay. Do that in your cell phone.
It is my laptop
