SMD Soldering - the easy way

I have been prototyping a number of small circuits recently each using SMD parts, each time a new board comes in I need to solder up a few of the boards for testing.
To speed up this soldering process I have come up with a simple workflow that doesn't require much set up, equipment or tidying up.

This was very helpful to me. Thank you for the attention to detail. Your commentary was insightful for someone who has done some through hole work and not yet done any SMD. :)

Melt a ball of solder onto one pad first, reheat the ball and insert one end of the component into the ball. Let it cool. Solder the other end. done!

After many many many failures I finally feel confident enough in SMD soldering I can't risk damaging.

I've found that it's nice to apply some extra solder to the first joint after the second one is done, the new resin will freshen it up/remove oxydation so it won't be a "cold joint" anymore.

I had solder paste gone bad once. It forms more unattached balls than sticking to the pad at all. It's the flux that does stop working. It also does not keep it's shape when applied with a stencil. Using a syringe with a nozzle is not easy. Pressing the syringe and holding it still at the same time is next to impossible. So appying it with a knife tip seems a good idea.

Take the IC flip it over apply paste to the pins then flip back over and apply heat ! DONE !

@shashankks1962 3 жыл бұрын

Good video for beginners. But you can use additional flux to make your soldering way more easier. Coming to your board design, your pcb routing can be improved a lot. You can add copper pours, have gnd and vcc plane and so on.

Did you ever consider soldiering by pre-tinnig the pads?

@mitchkolton6198 4 жыл бұрын

Pads that are NOT pre-tinned are copper. These are tinned as they are silver in color which indicates solder!

I don`t quite agree with the reducing the part count theory, but it is an example of reflow soldering.

If you have or know someone who has a vinyl cutter, you could use that to make a template to place over the board, then place the template over the board and slide the paste over the solder points, remove the template, place your parts, warm up the board and all of your parts will center themselves onto the solder points.

@ArthurGuy 7 жыл бұрын

I tried making my own stencils using a vinyl cutter and had some mixed success, the template I made did work fairly well but the effort to make one wasnt worth it for the very short runs I was doing.

@principedinerezza 7 жыл бұрын

Fair enough. I view everything from a graphic designer's perspective so I am willing to spend a little extra time building a stencil but I understand why many people wouldn't as mastering the skills to do it quickly could be very daunting and time consuming.

How long did it take for you to fweel comfortable doing smd soldering,I just bought a 898d soldering station with heat blower,and soldering pencil,so I can do this ,I have already mess up one cheap kit,the liquid flux I used seem to eat away some of my pads,imhave a thirty year old cream soldering paste I will be using,until I can order some like you use,is your paste lead type or non lead type paste

@ArthurGuy 7 жыл бұрын

If you can get away with it leaded solder is so much better. Solder paste will dry out so i'd replace what you have.

@cdevidal 5 жыл бұрын

When you order the board request a solder stencil so you don’t have to manually lay paste :-)

@cdevidal 5 жыл бұрын

Unrelated to the video content but it seems your board has too much etched away. I am expecting to see more ground plane. I’m an amateur though so maybe I don’t know what I’m talking about.

my smd solder paste is very thick how to thin solder paste?

@royglennie 6 жыл бұрын

Great video! Sorry noob questions here, doesn't the heat damage the chip? I thought they were very sensitive to being heated. How do you avoid this using the heat gun? Oh and did you use 320 degrees Farenheit or Centigrade?

@ultrapetey 5 жыл бұрын

He's British - it's Centigrade. Also, the melting point of Solder is around that temperature in 'C as opposed to 'F

@alphabeets 4 жыл бұрын

SMD parts are designed to be heated like this when they are getting soldered.

@mireazma 8 жыл бұрын

For the chip: how can you make sure that the paste has properly/equally retracted to the pins and not short circuiting or left a pin bare? It looks very straightforward, bother-free but is the result reliable?

@ArthurGuy 8 жыл бұрын

I use an eye loupe to look at all the contacts, it doesn't take long and it's fairly obvious when there is a short or the solder hasn't flowed.

@Pops180 6 жыл бұрын

The solder joint looks ugly because it's a cold joint. You should apply flux and reflow the first pad. This is how it's done using your method

nice boards ... why not use a stencil for the paste and a small oven for the overflow? the method is well described in elecktor magazine

@ArthurGuy 8 жыл бұрын

+Sérgio Jácome I have tried them both, stencils are really convenient but cost money and most of these are meant to be really cheap prototypes. I also tried making them with a vinyl cutter and had some success. Reflow oven was ok but for a small quantity of boards the hot air was more convenient. But I probably should have given that one another try.
