    I forgot to mention: application is done with a hot bar and mild pressure. My tape for example (AC-7106U) needs 180C and 2MPa pressure for 10-15 seconds. Strange Parts shows how it's applied to an FPC about two minutes into this video if you want to see it in action: ua-cam.com/video/ks-lS11TIaY/v-deo.html
    The adhesive ends up being closer to a permanent heat-set epoxy than a removable tape adhesive. I'm trying to debond the microchip right now to take a closer look, but it's proving very tenacious!

      Thanks for that additional info. That was the biggest question I had after watching this. Trying to work out how hard they need to push the component down on the tape to crush the balls, and how it doesn't just spring back off, In other words, what keeps the pieces clamped together? Also the example where the traces were contacting the pads without the aide of the balls, I was trying to work out how that happens when there should be some thickness of tape between them. Heating it must liquefy the carrier compound to an extent that it pushes out of the way, and cooling it would set everything and hold it in place.

    I suspect one of the reasons they used electroless nickel phosphorous plating on the pins, aside from corrosion resistance, is that it promotes surface uniformity and reduces surface porosity. Ensuring that there are no surface voids or pits is likely a fairly major reliability factor for applying the tape. Since bare metal is fairly porous, there's a tendency for hydrogen absorption (and adsorption), which might lead to bubbling and delamination of the tape as a result of degassing. A medium-phosphorous EN plating is a pretty simple and relatively cheap way to solve all of those problems simultaneously, and the tooling for it is pretty ubiquitous given that we do it all the time on ENIG / ENEPIG surface finished PCBs.

    If you have a green (best color for visibility) laser pointer, you can reflect it off if the surface of a TV or other screen and see the individual pixels in the reflection. You can also do this with a CD or DVD to see the track made of pits and lands.
    I've been fascinated with this effect of using laser light to view microscopic structures as a reflection. With no lenses. I'm wondering if this method is used in actual scientific applications to visualize microscopic structures.
    I always find my best ideas have already been thought of, so I expect that somebody would have discovered and exploited this in the last 50nor so years.

      Have you seen how holograms are made?
      Also, obligatory cheap green lasers can punch your eye out with invisible and undetectable 808nm and 1064nm infrared light. Any DPSS laser like the common 532nm is packing a pump diode that puts out much more than the "safe" 5mW legal limit. Some have IR filters, most cheapos don't.
      Most any other diode laser, including the new green ones (~500-520nm) is probably grossly underrated on output power due to marketplace regulations. Before those regs, they used to sell them as toys to light stuff on fire. Now they have to be below the legal limit to sell but of course nobody setting these rules ever checks anything.
      Be careful with those reflections!

    You're correct about the corrosion resistance for that nickel coating on the pads. We do the same thing for the copper IHS on CPUs. The nickel doesn't corrode away nearly as badly as copper will when just exposed to the atmosphere, let alone any moisture. You wouldn't want to have your traces going green on you, or the surface of your CPU becoming pitted over time.

    • @peoplez129
      @peoplez129 Рік тому

      Chips won't go pitted, because there's generally a layer between them and the IHS, such as thermal paste or pads. So even copper in contact with an IHS doesn't really corrode in its usable life, because it's protected from air at the contact point. Of course everything else would corrode, and that's mainly for aesthetics rather than functionality.

    • @DigitalJedi
      @DigitalJedi Рік тому

      @@peoplez129 It's not the inside we're concerned with. That is sealed from the outside world. The silicon itself won't corrode, since it already has a layer of oxide on it. The greater concern is the outer surface, which is exposed to the atmosphere for extended periods of time. Pitting takes a long time and is the extreme example, but even tiny copper oxide spots ruin the thermal properties of that area of the IHS and create hotspots.

    Fascinating, I guess the unsung hero here is the coating and construction of the spheres as at this scale the odds of them touching and forming a bridge are small but even if they do the 'point contact' area on the sphere is ridiculously small ! so the ability to be 'crushed' and spread out a conductor is the key to this. I wonder could the spheres be an insulator but the insides be a crushable conductor ? It would work a bit like crushing a profiterole and the cream is conductive, but it wouldn't matter if the choux pastry touched as its an insulator..... I love it....cheers !

    Thats amazing! You wouldn't think just a couple of those minute squishy metal coated balls would be enough to allow enough electricity across to pass the signal or power across, but I guess at those scales you don't need as much contact as I thought. It's kinda also amazing that glass can have so many electrical traces running across and through it, and yet still remain perfectly transparent to our eyes. You'd expect the glass to take on a sort of frosted appearance but again, I guess just like bacteria and microbes in water - once they go below a certain scale in size they effectively turn invisible to us. Hence perfectly clear water ends up being anything but, once you view under a microscope.

    It seems like the crushing of the balls not only allows a larger contact area, but also makes it possible to have smaller balls that reduce the probability of the hollow spheres bridging to each other

    This is one very good example and explaination of a phenomenon I'm still very much amazed by: micro- and nanostructure production is so much more cost effective then mini scale! You set up the general properties of the process and physics does the job for you, while with conventional manufacturing, be it subtractive or additive, you have to think of speeds and pressures of every single movement of the tool and the reaction of the blank to it.

    That small microchip is driver IC and connection points we call it Au bump.
    Usually made by sputter TiW and Au layer on IC’s Al pad (UBM layer) then plating Gold on it, also we have Cu Ni Au bump and Cu bump processing.
    In this video cross section is Au bump definitely.

    I love your video and since this is the first video of yours I'm watching, I subscribed right away.
    On the 'negative' side, your illustration at 0:55 shows the X axis in green, while you're explaining that the z axis is conductive. It created a great deal of confusion for me 😕

    Another cool product used in electronics is an adhesive thermal interface material that guarantees electrical isolation. This is a dispensible glue like material that cures and include small glass micro-spheres that guarantee a minimum gap when you apply pressure between the part that is being thermally bonded to the heat sink

And all your topics are so interesting, even the off tangent ones. And you visual explanations, i knew about this principle existing, but your explanation is superb. Thank you for making all your videos, really great work

    @912 - The pads seem to connect without the microspheres -- remember that the pad is going down into the microscope; you're just looking at a single edge, so there are probably 4 or 5 spheres deep for contact.
    It's probably also the reason for the enig process -- none of this works too well if our PCB (flex or not) gets oxidized.

    Hi Breaking Taps, I appreciate what you say at the end about skills and hats. As interesting as the content of the video is, your "rant" or lead-in to skill share, I found myself nodding in 100 percent agreement. The drive you must possess to produce your videos should not go unrecognized. Standing ovation for your determination. The world we live in requires all of us to wear many hats. Only the most dedicated and driven personalities could do what you do. A regular job that pays the bills has been or soon will be relegated to a moment lost in history. We live in an every increasingly complicated world. The knowledge that there is a valuable source for learning such as skillshare is possibly more important than knowing spheres make single dimension electrical connections. Question; who has an electron microscope in their garage? 🤔 Keep the vids coming, always interesting.

    Why do they cover plastic spheres in metal, and not the other way around? Wouldn’t that guarantee that even if the balls touch each other all the way to another contact, the shells aren’t broken, and therefore cannot conduct electricity?

    ok, I get how the copper tape at 3:06 is conducting to itself, that's obvious. But how is it conducting to the metal it's taped onto?
    Is the adhesive conductive too? Or is it so thin that the electrons just jump the "gap" between the tape and it's taped on surface?

    • @BreakingTaps
      @BreakingTaps  Рік тому +1

      My fault, I explained that poorly! The adhesive itself is conductive, I think it's doped with something like silver particles, and has enough of the particles loaded that there is always a conductive bridge between the copper and the underlying substrate

    9:06 Where does the substrate of the tape disappear to? Somehow it must be penetrated by the microspheres when they are crushed.
