Thanks for your question and I'm glad to hear that our videos are effective. To answer the question about the DFN directly, Yes, you will need hot air/gas to solder or desolder the component. It's just not possible to get to the thermal plane under the center of the component with an iron. Some DFN packages are designed in such a way that it's not even possible to solder the individual leads since there's no toe surface or termination visible at the side of the component.

Very nice results as opposed to drag-style. This looks easier for beginners, but some of the drag-soldering videos produce same results in much less time. I will be getting a new station soon, so I can try both methods :-) Thanks for posting this, cheers.

Nice work. I've always wondered how people soldered these tiny pins by hand, and I actually imagined that you would solder across an entire row of pins and use a very fine cutter between the pins to make sure they didn't connect :)

Sorry, future tutorials will not have that on them. Thanks for the comment.

Lead free solder may be good for the environment but is not good for very many heat-cycles in real applications. BTW, that solder job in the video is pretty masterful. I loved the demo!!

John Thanks for the comment we try our BEST here at BEST to meet or exceed our customers expectations in our video tips as well as our training programs.

BOOM! Thanks for the hot tips, can't wait to try them out.

Fine video presentation. If solder truly sticks to the copper like that without bridging, then I should have no problem soldering.

Man, you are the best that i,ve seen ever!

Very good, clean job.

The equipment that I am using in the videos is a OK Industries (METCAL). I have used PACE, Edysin, HAKKO, Weller, and JBC. These technics work well with any type of equipment. Just practice. Thanks for the comment.

*I have been watching verious soldering training videos for the past two days now and is sad to see that nobody is telling us what type (make) of flux or solder they are using. I believe that is very important because there are quality flux/solder, and there are cheap ones. It makes all the difference including the iron temperature.*

Thanks for your comment.

It called dry tacking. This is where you don't use any solder but flux and heat. What is going on is there is some solder left on the pads site after the part has been removed and cleaned. This is enough solder to hold it in place once you apply flux and heat.

good videos and instruction, thanks!

Thanks for the video its a nice idea to upload many people can learn from it:)

Thanks, lots of practice.

Actually I am using a METCAL SMTC 0147 tip. So yes to your question.

Magnifying ring lamp

thanks for your comment

Excellent!

Its just wonderful!

this video is very good congratulations

That's a hot tip. How many watts is the soldering iron?

BOOM! CLEAN THE TIP!!!

With the hoof tip I can get more than one lead at a time but also it covers more surface of the lead at one time. With a chisel tip you have to drag it from the heel to the foot but with the hoof you cover the whole foot at once.

Aptly Great job Sir.. What is the soldering power (WAT) value.. It's looks 60w isnt it. ✌️Thanks v much.

Wow, that's like magic lol. Always wondered how those little legs got soldered in place.

Yes, and patients is next.

It is Alpha Rosin 800

Hi Norman. What soldering equipment are you using with that hoof tip? Also, what other soldering stations do you use on a regular basis, if any? Thanks and great videos!

how did you "tack" the corners? that is a new concept to me, mostly because i didnt see any solder involved.

I use ISP Alcohol to remove the flux residue. If left on the board it might cause issues.

What kind of system? That depends on how much capital you have. I generally don't recommend hand-held heat guns for any application. The time and temp profile created by using the heat gun is so variable that it can be very difficult to get consistent results. There are table top systems for less expense which will do the job sufficiently all the way up to monster, automated rework systems. It's up to you to do the math and the homework to determine what's best for your application.

Thank you sir!

So, do you just leave the flux on the circuit board or do you clean it up? Does it just dry into the circuit board? What do you clean it up with?

nice work tanq

any idea what type of solder apple uses on there iphones and what the melting point of the lead free solder is? thanks

thanks master...

What type of flux are you using? You injecting it as I see... I normally use flux pens... But never tried yet this type of soldering however it looks time saving so I might should try it! If you could point out what soldering iron you use and flux etc would be much appreciated! Cheers

Where do you get your no clean liquid flux, because the liquid flux I have leaves residue that is sometime a pain to get rid of especially if you are working in close quarters with other components?

whats that water stuff he put on there to souder it?

Excelent ...Thanks you

Hey! How did I end up getting a negative rating?

Which soldering iron, and which inspection camera is being used here? Thanks.

how can u tell which pin number on the IC? and where to place it? also is there many different ways these type of chips are lined up to the PCB?

What is the tip temperature you are using?

Norman (or others) - a question re: this technique. Out of curiosity, why use a Hoof tip vs a Chisel tip - of the width corresponding with the number of pins you're trying to do at once? It seems like the shape would more correspond with what is being done. But I'm likely not understanding something re: the choice. Thanks in advance!

Several solder distributors handle that size but it is expensive.

BEST, Inc

good....

Did he said hill fillets? Is he the fastest master solder out there?

Sorry, thanks for the tip and for the future videos we will try and prevent that.

cool..

Amazing :D

Please define your technique.

To me, that flat pack you put on is ok but the overall quality of the joints look un even.Yes its better than some people but I use the drag method,little as possible solder on the tip, plenty of flux and go! I like the whole 4 sides to be even just like it comes out of a machine.Brush up/clean with cleaners not alcohol.

I don't understand the question.

i dont know how to use flux can some one please help me!

looks like very good work, but much practice is required, isn't it?

Be warned... he makes it look easy. Wonder if he's ever used Sparkfun's "Special Blend" unleaded solder with 3% silver and what he thinks of it. It's actually easy to use compared to other unleaded solder blends I've tried.

@BlindedByEvil ok thanks

bup bup... nice vid.

Or I use the heat gun, (once chip is dry to eleminate white dry flux residue. I prefer a standard no8 chisel/conical tip bog standard weller to a better job than your vid. ;) If thermal exposure is a problem or pcb has lots of ground plane,then i use weller heat gun to warm pcb gently before soldering. This helps flow.

@sectoras rofl indeed

It is a good video EXCEPT, for that BIG RED BANNER that floats across the screen every five seconds reiterating what you already said. How about moving that banner into the top part of the video screen because on a few parts, it would cover some of the work you were doing. Lot of good info but a lot was wasted.

Well, why doing it Lead Free? Lead based 60/40 solder is better for any solder iron tip, because the copper can damage the tip. Also, you don't need to go as high in temperature.

Poor editing but great video!

I can't take advice from someone that confuses flux with solder.

stupid text in the middle of the video, remove it next time, cant see the important thing you are pointing

Annoying.

Which soldering iron, and which inspection camera is being used here? Thanks.
