    Maybe it's just me, but there's something really trippy about the way that microscope is set up and how well it is lit, it looks like we're watching 3D rendered stuff but it's actually real life

    • @Pi7on
      @Pi7on 3 місяці тому +69

      I'd say it's mostly due to the focus point being stationary when both the microscope and the board are moving. Looks like the focus is at the center of the 3D rotation.
      Also the lack of vibrations.
      It really does look like a 3D render lol

      exactly, it looks like orbiting virtual camera around 3d model in blender/3ds max.... The mechanical precision of this makes it look like a 3d environment. This just not happens while hand operating camera or even with simple camera rig therefor the motion itself sells it as a 3d. Funny thing is, it can happen in reverse. Motion capture human operated camera apply it to fairly photoreal scene and motion itself helps to sell that 3D render as a real video.

    I have a soldering certification that is even more stringent than what NASA requires. Towards the end of the course we solder a 140 pin flat pack using a soldering iron only with a 0.5mm pitch by hand and the expected quality for certification is as you described where the solder flows up a specific ammount at the front and back of the lead, but we also look for stress cracks, pitting, deweting and the tiniest traces of flux. Basically, the solder joints all end up with a mirror finish to it.

    6:10 This is something that many of us know, but few teach. Touching the solder to the iron as a catalyst to get it flowing. Once you have a little liquid solder, all is well. You can really overheat the pad/component trying to get the solder to melt without touching the iron.

    • @goodun2974
      @goodun2974 3 місяці тому +10

      Soldering instruction is often incomplete ---- they always tell people not to touch the solder to the tip of the iron but to apply it only to the parts being connected, which invariably leads to poor thermal transfer from the tip of the iron, which means that you end up applying heat to the connection for so long that you can damage the board, lifting and delaminating foils or, in the case of the header pin with too much solder shown here, melting the plastic strip and pushing the pin off-center. Anyway, I have been soldering for nearly 55 years, and for as long as I can remember I have done it the way it's shown in this segment of the video, where you touch the solder to the tip of the iron just for a second and then move the solder away to the other side of the connection.

I've personally never been able to examine BGA soldering from that kind of perspective before, since I'm usually staring at the chip from above through a microscope and positioning my tweezers to ensure the chip doesn't fly away when I'm using hot air. I see the end result though, as I tilt the board to examine each side of the chip to ensure, at least along the edges, there aren't any complications. Very impressive stuff!

    At 06:05 you should place the iron and the solder at the same spot on the pin simultaneously, the solder will help carry heat into the pin. You should also remove the iron and the solder at the same time, or the iron very shortly after the solder. If you leave the iron on too long you boil off the flux and the solder wants to "follow" the iron off of the part (makes little solder-sicles).
    When you see the pin push free to the left it indicates that you held the iron on the joint too long and melted the plastic holding the pin on the other side.

      I was taught differently. Put a drop of solder onto the tip of your iron and add more solder from the other side. This avoids „cold“ joints brcause The additional will only melt if both the pin and the eye are both enough the be wetted by the solder.

    • @donbarr9487
      @donbarr9487 3 місяці тому +1

      @@MrAranton I think the same result is obtained either way if you do so at the joint. If you do so too far from the pin the flux will boil off the iron before you get to the joint. You just don't want to hold a "dry" iron to the joint while waiting for solder to melt on the other side of the connection. The iron, solder, and flux all work together to get a good joint.

    At 7:07 , the header pin actually goes a little crooked and stays there because heat was applied for too long and the plastic strip on the other side softened and melted, allowing the pin to shift as the soldering iron puts excessive sideways pressure on it. When the solder hardens, you can see that the pin is a little off-center.

    Hand soldering: it looks like you shouldn't keep that much heat, so the pins are starting to wobble in melting plastic holder.
    I often rise up iron's temperature to make it solder faster, so plastic have no time to melt.
    Also proper surface tensioning flux helps to fill all gaps with solder fast.
    Thank you for making and sharing these great shots! Really helps to better grasp on what's happening over the pads

    • @goodun2974
      @goodun2974 3 місяці тому +2

      Yeah, I saw that header pin shift sideways when the (unseen) plastic strip softened and melted. Unfortunately turning up the temperature of the iron isn't a very good solution because the higher temperature tends to quickly oxidize both the connection and the tip of the iron, and so neither one wants to really wet to the solder unless you use extra flux or the flux contained within the solder is particularly active and effective. It's better to make sure that the tip of the iron is scrupulously clean and freshly wetted with a thin coating of fresh solder, and the connection being soldered similarly needs to be oxidation free. Under those conditions, if you're still having problem then you can try turning up the temperature of the soldering station a little bit. It's also important to use high quality, name brand tips in your soldering iron because most of the bargain-pack tips sold directly from Asia or China are made of iron or steel, not plated copper, and have poor thermal transfer characteristics. High quality, plated copper tips will be attracted to a magnet only at the pointy business end where they are intentionally plated with iron to resist the dissolving effects of molten solder and flux. Cheap tips will invariably be attracted to the magnet throughout and at the back end of the tip. I posted a video about this on my channel recently.

      Unfortunately, leadfree solder is an all-too-frequent exception, where finished connections often look dry, grainy and dull ( like the BGA soldering shown). Perhaps it looks better if you're using one of the fancy and expensive soldering stations that have a hose where you hook up a nitrogen tank to it...... but if a solder alloy is so finicky that you need to flood the area with inert gas to keep oxygen out of the connection, then it's not really practical for home hobbyists......

    Thanks for a cool video. To be picky, the lead free soldered joint looks like a 'dry' joint. Also, when hand soldering, try adding a spot of solder to the iron before putting it to the item to be soldered, then add more solder to the side opposite the iron, this will stop the tendency to push too hard with the iron because the heat transfer from iron to joint will be faster.

    Reminds me of my old job, did repair all kinds of mainboards (PC's), like Asus, Abit, MSI, Aopen, Gigibyte. Did replace all kind of chips and other components like CPU, PCI, AGP, USB you name it sockets. Had a great time back then ;) Anyway great video.

    Nice! As I only know about hand soldering, I missed the part how the PCB is heated while soldering. Is it heated locally? How is overheating damage to electronics prevented? Will other components not come loose while trying te solder a new component?

    • @goodun2974
      @goodun2974 3 місяці тому

      Heated with hot air, perhaps even from underneath the board, or top and bottom simultaneously.

    • @goodun2974
      @goodun2974 3 місяці тому

      Heated with a directed stream of hot air, perhaps from underneath the board or from both sides simultaneously.

    How do you know that the pins underneath are soldered properly? Do the chips have scan path diagnostics to verify soldering? Verifying no shorts to nearby pins?

    what are you using to solder especially the QFN? I'm guessing at least an under heater, but surely that can't alone be enough? so hot air from above? it didn't look like it because i couldn't see any optical distortion from the heat. but perhaps it's too magnified to see it.

    How are the BGAs produced? Same sized balls production and then placed? Maybe you can make a video on that one day!

    • @ProtonOne11
      @ProtonOne11 3 місяці тому

      Yes, they are prefabricated balls of solder. You can even buy them, just like soldering paste, in different sizes for "reballing" a chip if you need to rework a bad solder job.

    Very cool! That is one hell of a scope! I tried to look at pricing but it bugged me for my email then didn't work when I gave it. Oh well. I'd imagine these are quite pricey. Is there a software subscription license for the software component?

  • @d614gakadoug9

    Even with the correct amount of solder paste you can get the paste spreading excessively if you are not careful with preheating. It takes a considerable amount of time to properly preheat so that any volatile constituents of the flux are driven off slowly and don't boil. Proper preheating and limited rate of coiling are also critical to reliability with multilayer ceramic capacitors.
    With leadless IC packages the part of the "pin" that is easily visible does not need to be neatly soldered in order to produce a reliable joint. This part appears to be bare copper because that is exactly what it is. Low-activity flux, which includes almost all "no-clean" types, may not be adequate for good flow on the bare copper. Added to that is the possibility of some smear of the plastic from the package on the bare copper as a result of the trimming process.

    Great demonstration of capillary action that causes the solder to creep up the leads.

    • @user-ns7qw9hd5y
      @user-ns7qw9hd5y 3 місяці тому +1

      i think its not even (just) capillary action, but also "normal" adhesion, no? the liquid solder sticks to the metal, but not the pcb?

    • @goodun2974
      @goodun2974 3 місяці тому +1

      ​@@user-ns7qw9hd5y, the PCB is coated in "solder mask" or "solder resist" to prevent solder from sticking to it. Surface tension of the molten solder tends to make it form into a ball when it's sitting on something like a coated PCB that it cant wet to, and the only reason that a solder ball might stick to the board is because of the flux acting like glue when it cools.

  • @Blue-Maned_Hawk
    @Blue-Maned_Hawk 3 місяці тому

    I find it quite interesting to see the capilary action of the liquid solder traveling on the leads and pads-it's not really something that one would think about, but makes complete sense when you do think about it. After all, capillary action doesn't care what liquid it's acting on, so molten metal is as good a liquid as any!
