Soldering MCU & QFN IC Chips with Hot Air Station

This video will show you how to reflow solder a QFN chip.
We will remove, inspect, and replace an MCU (microcontroller) using a hot rework station.
The hot air station is 1000 watts, and the flux used is ChipQuik NoClean 30cc Syringe.
Hot air temperature setting is 385C and 36 air speed.

I'm about to reflow a QFN and 0402 chips. Just watched and got some feelings about it. Thanks.

LoL . . . . . No heat protecting tape to cover the surrounding components

[curtisnewton]

"and that is excellent" did you test it ?

[blackfish]

Very clear and insightful video. thanks!

Ever tech seems to have their own unique way of doing this. Nice work!

New subscriber here. That's a good way of showing different video angles. Thank you.

I don't know why there is solder mask on the bottom exposed pad footprint. That proably makes it more difficult to solder properly.

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?

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 YouTube. 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.

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?

[GeItron]

How you do that, iam heating since 1h nothing happened

[seanocansey]

Thats a clean board, did you design it?

[rodrigozaracho]

a que temperatura usas la estacion y cuanto de aire.

[curtisnewton]

the brush is really gross, any reason for using that ?

[cynthiajimenez]

This is a helpful video. I am a beginner and always worry about having to take a component out and replacing or repositioning it…

[DiversificationPlus]

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

[corychamberlain]

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?
