3d Printing Solder | Hackaday

March 10, 2016 by Bob Baddeley

The general process of circuit board assembly goes like this: You order your PCBs. You also order your components. For surface mount components, you apply solder paste to the pads, put the components on top, and then heat the board up so the solder paste flows and makes a bond. Then for through hole components you put the leads through the holes, and solder them with an iron or a solder wave or dip. Then you do an inspection for defects, program any microcontrollers, and finally test the completed board to make sure everything runs.

The tricky part is in volumes. If you’re only doing a few boards, it’s usually easiest to assemble them by hand. In the thousands you usually outsource. But new tools, and cheap hacked tools, have made it easier to automate small batches, and scale up into the thousands before outsourcing assembly.

In this new series which we’re calling Tools of the Trade we’ll be covering a variety of tools used for building products, and we’re starting with circuit board assembly. Let’s investigate our tools of the trade: solder paste dispensing.

[Bam] from the LulzBot forums  has successfully printed metal using his 3D printer and a Budaschnozzle 1.1 hot end. Well, solder to be specific — but it’s still pretty awesome!

He’s making use of 3mm solder purchased from McMaster (76805a61), which has a blend of 95.8% tin, 4% copper and 0.2% silver. It took quite a few tries to get it extruding properly, and even now it seems to only be able to print about 15mm before jamming up — a more specific hot end with a larger thermal mass might help. He plans on trying a thinner filament (1.75mm) as it might help to keep it at the proper extrusion temperature, which in this case is around 235C.

During our research we found another user from the RepRap blog who has also been experimenting with printing low-melt point alloys — and he’s even successfully created an Arduino compatible Sanguino board using the printer!

If you want to try this yourself, you’ll need a nozzle you don’t care about, bored out to about 1mm — any smaller and it won’t extrude at all. Be warned though, the solder will corrode brass and aluminum, and [Bam] notes that after going through 1lb of solder, the nozzle was closer to 2mm in diameter when he was done! Oh and for the love of hacking — use ventilation!

Stick around after the break to watch a video on a professional version of this system — which is essentially a repurposed welding robot, using electron beam direct manufacturing. These technologies can’t make nicely finished parts, but they excel when considering they can make near net-weight parts, requiring only a small amount of machining to finish.

Solder dispenser. Another one, "at the request of the workers";)

There were some interesting suggestions and comments in the dispenser's past review. I carefully read them all, thought it over, and here it is, our answer

to Chamberlain

Perinsky, and to all commentators.


So, one of the options “on the topic” was this photo

As it turned out, the author’s name is Valery Perinsky and he lives on thingiverse, and this model is here.
I tried to print this dispenser and I had a few questions. in particular - what for was it to break the coil into THREE parts? At least the middle one can be combined with the top one. Moreover, the author used two magnets - one 10mm in diameter and 4 thick, and the second - 9 mm in diameter and 5 thick. I must say that this is quite some kind of rare earth magnet. In the sense that you will not find it in every land. On Ali, in particular, I found such a miracle from only one seller, and I didn’t like the price with delivery. The second question is how, in fact, to unwind the solder ?! Reel rotation? Hmm... but that's not our method!

Next, we watch this video and admire the idea, we are impressed by the implementation:

Hmm... And if we combine brands? ©

At first I wanted to fix the existing model, and then I decided that it would be easier to redraw from scratch. Almost. We take a sketchup…

Well, we print. I printed, as is easy to see, in a mirror image. Coil:

The dispenser itself.

We need a wheel from a lighter and a plate made of something springy, like brass, which needs to be bent at an angle of about 120 degrees somewhere around 0.3mm). Well, cut the M3 thread in the housing for the screw securing the cap. You can go through the holes for the wheel axle with a drill - they may turn out slightly out of size, they are small. Well, it is possible that the wheels themselves come in different sizes - this is China ... These wheels are also directional, but in my opinion there is no difference in this application.






Actually, I liked it so much that I printed another one so as not to rearrange the solder.

As you can see, there are no magnets. They are already ordered, but everything works in principle without them. How exactly - look at the video

IMHO the result turned out to be quite sensible. It is both aesthetically pleasing and comfortable to use. Thanks to everyone who pointed me to these dispensers (both on Singivers and on YouTube), thanks to the authors of the developments, and use it to your health.

ATTENTION! The file has been re-uploaded, for some reason there was an error in the original. Moreover, I edited the model again and ran it through netfabb for the lucky owners of simplify version 4
