In video I missed to explain that the 4-layer mother-board have 2 other layers with grounded polygon pours.. Also as pointed out in some comments below, the long grounded thermal-track might act as antenna picking up rf noise. This is a trade-off for this self-reflowing concept, but to minimize the noise I added the possibility to short the track to ground from the two ends.

I build circuit boards for small satellites. Because they operate in space, keeping them warm is extremely important, and we attach external thermal heaters to them. I've thrown around the idea before of using an internal heater wire just like you have here, but never thought of using it for soldering. Very neat, will be interesting to see if this can remain reliable for other circuits!
@mandi8345 Рік тому
On a side note, I wonder how solder in micro-gravity would react.... Like, if there was a fault somewhere, and it got zeroed down to a bad joint, would it be fiesible to send the board through a quick reflow cycle. Of course depending on the instruments onboard it could be a bad idea, out gassing or having essentially a big antenna in the board (although....could it be used to pick up external EMI and used for data correction possibly increasing sensitivity or detecting some kind of EM event to protect the rest of the circuit.... hrmm, Im not into RF voodoo enough to know, just a random thought...), but integrating a heater strip in the PCB would certainly cut down on the individual components provided someone doesnt put a backup external heater in the SOP.....

I can't speak for Carl, but perhaps the inspiration was a short on a board. They can get very hot. It's not much of a stretch to go from there. I think the main reason for not doing this is that it's a slow process compared with simply running it through a reflow oven. Or a hot plate for that matter. The person who had the idea of putting tiny balls of solder in paste flux is the real genius. Why mess with an iron and solder wire when you can just smear past and heat it up.

It's a very inventive idea! I might worry about using a long meandering trace as a ground plane afterwards. If there were no taps to the circuit except in one place, the 'plane' might act like an antenna and pick up RF noise. If there were multiple taps instead, I'd worry that they may offer alternate current paths during soldering.
@Mr_Lambda Рік тому
You will need to create an additional layer with a proper ground plane and yes, a whole layer made of a long coil might create some issues, especially in high frequency applications. That's basically a huge inductor it might even create a large parasitic capacity on the board

@sebastian.salmhofer Рік тому
I wonder if you could just use a regular ground plane as the heating element. One connection along each side of the PCB. It would require much higher currents and it might not heat the plane evenly, but since copper is very thermally conductive, the plane could maybe spread the heat well enough. Could be worth a try. A welder might work as the power supply if the current can be adjusted down low enough so the PCB doesn't instantly vaporize.
@SpaceMarshalGyorni Рік тому
You could always shorten the trace by adding vias in various points connecting it to the top surface, where you could connect them later via more zero-ohm resistors, perhaps. Not sure how practical that is since the bridges would have to be added after the initial reflow is completed.

Absolutely. I think this is a huge leap forward for small/individual board designers.

Now anyone could use this approach to sell small SMD kits without the need to pre-build boards. Only issue is the cost Carl mentioned. Sometimes I forget I'm not watching a big electronics R&D company channel when I'm watching Carl's videos.

@conorstewart2214 Рік тому
@@gd.ritter if you are going to the effort of buying a kit where you need to tweak smd components you can at the very least buy a hot plate or something. With this you need a power supply, constant current is probably best unless they can work out what voltage works for that specific board which would take a bit of effort on the designers side and it needs to be quite a powerful power supply since there probably isn’t that much resistance on the heating trace and it will need relatively high current to get it to the required temperature. This isn’t just a one off solution since you will still need a decent power supply to get it to work. Edit: this is more complicated than buying a PTC hot plate and wiring it up, since they are self regulating and that would allow you to use normal solder paste to reflow it, not low temperature stuff.

There is one more thought - you can not use a thermocouple - you can connect the heating layer periodically - first to a current source, and then to a resistance meter - copper has a very linear function: R=f(t°) - so you can find out the temperature knowing the resistance of the heating layer.

Very "out of the box" thinking, really like it.

The next thing you have to do is cleaning the flux off with alcohol and you are ready to go! Pure magic! Love it!

Really cool idea though! One major downside to using this as a primary gnd plane though, would be that youre likely creating nasty inductances that can show up as ringing along your supply lines if there are many pulsing currents on this board.

Its even greater because you could potentially have boards where most comoonents will stay the same but where you leave extra tracks just in case you need to change the configurwtion and you can then do so at home just with component placement on a more hobby friendly pick and place like the LumenPNP

But the connectors I am thinking about, which need somewhat lower temps, only introduce low amount of mechanical stress, no matter how you solder them, because of the relatively long and flexible leads (they are designed not to add extra stress, because being connectors already adds external stress). Lower profile parts would likely heat up better with inside PCB heating, compared to connectors. So using PCB heating does not seem an instant death sentence as you seem to imply. You do have to rate each component for this process though, and doing an x-ray on every BGA part after reflow would be highly advisable to catch cracked balls!

Outstanding. I am very glad that someone did this. You are great!
@simonbaxter8001 Рік тому
Nice idea, BUT you really need to appreciate the very real EMI, EMC, RF and signal cross talk problems that those heater traces are going to cause! Maybe you need to learn some PCB layout fundamentals and signal integrity knowledge before pushing this idea too much as your stepping into design integrity minefield here.

I'm pretty sure anyone who is making a PCB capable of self heating and including a USB-programmable MCU and thermocouple probably knows what a wire antenna is... Relax a little.

@@ryanchojnacki4421 Not sure they do. And I'm pretty sure all those that think it's a good idea on here are being taught a really bad idea. This needs a followup with some real electronic principles and a demonstration of the issues it causes. Definitely not one for the average maker, but definitely one for those that will do electronics as a career.
@CarlBugeja Рік тому
It is definitely going to be a problem when the circuit on top is operating at high speeds. The examples I have given are all operating at slow speeds, expect for the clock source which I still think it's safe considering it's very close to the mcu and there are other grounded polygon pours on other layers.. But I intended this idea to be used for maker projects, and not something that can pass esd/emc/emi .. Maybe I can explore that in the future but as you pointed out rf is not my field of expertise
@simonbaxter8001 Рік тому
@@CarlBugeja Thanks for the comment. Anything above 10Mhz which any digital signal will produce (edge frequencies in fast rise times), the micro itself if it has a PLL, usb is above 10MHz, any SPI bus to peripherals port displays, etc. Robert Ferenac demonstrates in his videos the effects of these issues and the frequencies at which they become an issue. You idea is pretty innovative, but in my experience it would cause anyone who takes up electronics, as a serious career or business, some headaches. But I would hope that before applying this idea to a design, that they would understand the implications and rule it out as a very bad idea!

Cockbite. See if anyone lets you implement waveplates in PCB layers going forward.

Magic smoke just got a completely new meaning! I really like the idea. Might tinker with some of my designs soon.

Whoa. I'm currently working on a LiPo battery discharging circuit - want a super cheap board I can make 50 of and use them to keep my LiPos at storage voltage, and the entire back layer is just a long trace to use as a power sink when discharging the battery. This is literally the *perfect* idea for this project as I already have the trace, and need an easy way to solder up a large number of them!! Crazy, just crazy. I never would have thought of that. This is brilliant.

Just created a whole new kind of diy self soldering pcb, brilliant
@AgentPothead Рік тому
I like how at the end the pcb is charred and destroyed but the copper tracks inside look good as new, just looked cool.
