You should not need to check the mcu -> pad connections, unless you suspect a broken trace somewhere. Just use a multi-meter from the mcu pin to pad. Using a good flux will make sure there are no solder bridging issues too.
I started learning. Soldered a couple MOSFETs and driver chip on a laptop for it to work again but they fail soon after. Think I'm not getting the heat pad parts soldered well enough. Think I need to pay more attention to quality of flux and solder and play with temp more. More difficult than it looks from pros on UA-cam. I'm getting a little frustrated actually but I'll keep practicing when I get the time. I wish people would use temp gun to show actually temperature of surface they are shooting at.
Multilayer Boards always need a heater from downside to pre-heat the board. There are educational videos available from well-known manufacturers of soldering tools, like WELLER and ERSA.
Hello, I do it the same way you do but the chip doesn’t go back when I push it a bit and it burns every time, I tried lower and higher temp and air flow. Any tips?
Hi Faysal, make sure you have enough flux. When you move the chip just a bump should move back. To prevent burning, make sure you heat the board around the part, not the part itself.
It's hard to put a specific size per wattage, if you work on pcbs of varying size or pcb larger than 4 inches on a side, I would go for the 1k Watt station.
Hi thanks for watching; check the video description I have more info there . The temp is 385 C and 36 for air speed. You can regulate the temperature and the air speed by adjusting the distance the air nozzle is from the board. In Spanish: checa la descripción del video, ahi hay más información. Uso 385 C de temperatura y el aire a 36 de velocidad. Puedes regular la temperatura y el aire ajustando la distancia a la que sostienes la boquilla de aire caliente con respecto a tu tarjeta.
Ali, that is a valid point. Had there been any part in that area too sensitive, I would have covered it in kapton tape. But all those parts can tolerate the ~180C it took to melt the solder.
Ever tech seems to have their own unique way of doing this. Nice work!
Thanks!
I'm about to reflow a QFN and 0402 chips. Just watched and got some feelings about it. Thanks.
New subscriber here. That's a good way of showing different video angles. Thank you.
Good job, very illustrative. Thanks.
Glad it was helpful!
Very clear and insightful video. thanks!
Glad you enjoyed it!
I always wondering if the chip will stay healthy under these extreme temperatures. B.t.w. many surrounding components came lose.
Good job, well done. Is there any possibility to check the connexion between the chip termlnals and the different pads before putting it to work?

@@solderingironguide All right, thanks a lot.

please make an video with title : How to discover if a capacitor is in parallel or serie - thanks
Thats a clean board, did you design it?
Yes, also had help from my Altium designer. You always want to have more than one person involved in hardware design/layout.
@solderingironguide ideally yeah.
Looks really nice!
"and that is excellent" did you test it ?
temperature in 3:35 (soldering iron) ?
soldering iron is at 300 C, but you should vary it if you have a larger part or pcb.
@@solderingironguide kthanks
Qual nome desse flux ??

I don't know why there is solder mask on the bottom exposed pad footprint. That proably makes it more difficult to solder properly.
You might be right, but we follow the ref designs from TI when making our PCBs.
Super SIR
Verygood 👍👌
Thank you 👍
Hi, would a 500W station do the job?
It depends on the size of the pcb and the part you are working on.
@@solderingironguide For a job like this in the vid?
The pcb in the video is small, so the 500w should work fine.
@@solderingironguide Thanks mate! What size of pcb's are max for 500W?
It's hard to put a specific size per wattage, if you work on pcbs of varying size or pcb larger than 4 inches on a side, I would go for the 1k Watt station.
What temperature you set up?
I just set to 380 C.
a que temperatura usas la estacion y cuanto de aire.
Hi thanks for watching; check the video description I have more info there . The temp is 385 C and 36 for air speed.

@@solderingironguide thanks
How you do that, iam heating since 1h nothing happened
You need to have a good hot air station, recommend 1000 watt
This is a helpful video. I am a beginner and always worry about having to take a component out and replacing or repositioning it…
CC3220 SimpleLink WiFi, baby!
Yes. I love working with that chipset!
You don't renew benith the ic
the brush is really gross, any reason for using that ?
It's a disposable brush that's doing a dirty job. 🪥
Just budged that one chip above it.
If I was to send you a small board with a few parts that need reflowed , would you ?

Why didn't you cover the crystal oscillator?
It will be damaged by heat, right?
Ali, that is a valid point. Had there been any part in that area too sensitive, I would have covered it in kapton tape.
But all those parts can tolerate the ~180C it took to melt the solder.
I doubt crystal oscillator can handle that temps.
@@hazim38780 I never protect cristal oscillators while soldering with hot air and I haven't had any failure.
LoL . . . . . No heat protecting tape to cover the surrounding components

You should use flux ..and cap tape ...you have many small components near ...it's not indicated your method...good luck
