09:08:22 From Jon [Stem Inc] to Everyone: @Duaa thank you for starting w basics. 09:08:55 From Roland Grichnik to Everyone: I think going slow and starting with the very Basics is a very good idea for bootcamp :) 09:09:48 From Rico Kanthatham to Everyone: yes...warm up for the uphill, 6 mths, sprint to come! 09:12:02 From Esthefanny Salas to Everyone: which softwares do you recommend to use for design electronic? 09:12:43 From Rico Kanthatham to Everyone: Autodesk Eagle...and Kicad are the 2 software most popular for FA 09:12:50 From Krisjanis Rijnieks to Everyone: KiCad and Eagle are the ones people usually go with 09:13:02 From Adrián - Fab Lab León to Everyone: @esthefanny, you can try with Kicad, Eagle, SanpEDA... 09:13:36 From Krisjanis Rijnieks to Everyone: KiCad is open source and free. Also the new version 6 is a big step forward in terms of usability 09:13:54 From Esthefanny Salas to Everyone: What is the ideal temperature for soldering electronic components? 09:14:19 From Rico Kanthatham to Everyone: Eagle and Kicad are both supported with FabAcademy specific parts library...corresponding to parts your Fablab has in inventory. 09:14:53 From Esthefanny Salas to Everyone: Thank you !! 09:15:02 From Rico Kanthatham to Everyone: @Esthefanny...Duaa will likely answer in her presentation 09:15:14 From Roland Grichnik to Everyone: Fusion360 does Electronics now as well, if you want to integrate directly with CAD - it is pretty much Eagle in disguise though, anyway :) 09:16:03 From Devesh S Nair to Everyone: can't hear properly audio is breaking. 09:16:15 From Árni Björnsson to Everyone: Sound is good here 09:16:20 From Esthefanny Salas to Everyone: have you tried designing with solidworks electronic? 09:16:30 From Rico Kanthatham to Everyone: audio sounds good...check your earphone plug connection 09:16:41 From Krisjanis Rijnieks to Everyone: Sound is good here. Devesh it might be your internet connection. 09:17:29 From Krisjanis Rijnieks to Everyone: I don't think Solidworks has capabilites of doing electronics design automation. 09:17:55 From Devesh S Nair to Everyone: okay @Krisjianis. 09:19:36 From Roland Grichnik to Everyone: Make sure what you have at hand is actually solder… in our lab, someone once misplaced a small spool of tinned copper wire next to the soldering station - that caused a lot of confusion :) 09:19:46 From Rico Kanthatham to Everyone: @Esthefanny...theoretically...any PCB design software can be used to design PCBs. We recommend Eagle and Kicad because there is tons of expertise in FabAcademy on these apps...so trouble shooting will go faster. Also...as mentioned earlier...design images for Fablab inventory components have been made as a library...saving you the time to draw up your own footprint or search for it online. 09:20:56 From Rico Kanthatham to Everyone: fablab inventory libraries have not been made for other apps yet...as far as I know 09:21:10 From Rico Kanthatham to Everyone: *inventory components 09:22:50 From Krisjanis Rijnieks to Everyone: If you are adventurous and like to try new things, you might want to give SVG PCB a try https://leomcelroy.com/svg-pcb-website/#/home 09:24:22 From Roland Grichnik to Everyone: @Duaa: was the Copper cleaned or sanded before? 09:26:28 From Krisjanis Rijnieks to Everyone: For the flux - check if it is No-Clean or Clean. In the case of Clean, you should clean the residues after 09:26:48 From Rico Kanthatham to Everyone: ...with IPA 09:26:50 From Edu from BCN (they/he) to Everyone: Residue? 09:27:24 From Krisjanis Rijnieks to Everyone: The flux in the inventory is a No-Clean one so you are not required to clean it.. Anyhow it is better to clean the flux with IPA after, especially if you want to measure things on your board as it can cause bad connectivity 09:27:46 From Krisjanis Rijnieks to Everyone: Residue - flux remains 09:27:48 From Edu from BCN (they/he) to Everyone: ah, nice. tx 09:29:46 From Rico Kanthatham to Everyone: "bridging" = bad 09:30:34 From Jans Hendry to Everyone: Nice share @Kris, just tried with little experiment, thanks 09:34:19 From Roland Grichnik to Everyone: I'd add safety glasses to the list, sometimes little balls of solder get a bit spritzy from the rosin, so especially when closing in for a good view, this might get nasty 09:36:25 From Edu from BCN (they/he) to Everyone: what's the difference between flux / melted solder wire? 09:36:31 From Edu from BCN (they/he) to Everyone: are these the same thing? 09:36:35 From Krisjanis Rijnieks to Everyone: no 09:36:55 From Krisjanis Rijnieks to Everyone: Flux is a checmical substance that you use to prepare the soldering surface 09:37:17 From Krisjanis Rijnieks to Everyone: once it melts, it cleans the pads and it makes the solder to flow and stick better 09:37:23 From Edu from BCN (they/he) to Everyone: righttx! 09:37:45 From Krisjanis Rijnieks to Everyone: solder wire might have a flux core 09:38:04 From Krisjanis Rijnieks to Everyone: but in electronics they say that there is never too much flux 09:38:18 From Edu from BCN (they/he) to Everyone: lol 09:38:30 From Rico Kanthatham to Everyone: flux is your friend 09:38:46 From Krisjanis Rijnieks to Everyone: i love flux. i always use it. lots of it 09:42:35 From Matti Niinimäki to Everyone: Flux is also the most dangerous part of soldering for your health (in lead-free workflow) 09:42:53 From Árni Björnsson to Everyone: Dangerous how? 09:42:59 From Jon [Stem Inc] to Everyone: @matti why? 09:43:49 From Matti Niinimäki to Everyone: Long-time exposure can cause throat and lung irritation 09:43:55 From Jon [Stem Inc] to Everyone: any recommended reflow oven for fablab and any health issues? 09:44:13 From Jon [Stem Inc] to Everyone: @Matti, thank you! 09:44:24 From Krisjanis Rijnieks to Everyone: It is always good to have good fume extraction in place 09:44:29 From Matti Niinimäki to Everyone: https://blink.ucsd.edu/safety/occupational/hazard-control/lead-soldering.html 09:44:42 From Þórarinn Bjartur Breiðfjörð Gunnarsson to Everyone: it's dangerous in the way it turns into fume that will lead to health problems over time. 09:45:36 From Þórarinn Bjartur Breiðfjörð Gunnarsson to Everyone: the smoke you see is the flux fume 09:46:20 From Árni Björnsson to Everyone: Roger, thanks 09:46:40 From Edu from BCN (they/he) to Everyone: oh! thanks for this tip 09:46:59 From Jon [Stem Inc] to Everyone: if the paste expired whats the issue? Any required disposal method? 09:47:22 From Krisjanis Rijnieks to Everyone: fume extractor + cleaning your board afterwards = reasonably safe way of doing things i guess 09:48:21 From Krisjanis Rijnieks to Everyone: one should have a bin for hazardous waste. a bin with a lid. proper marking can help 09:49:24 From Krisjanis Rijnieks to Everyone: i think every country/region has their own regulations regarding hazardous waste. it is probably best to look up those 09:49:38 From Jon [Stem Inc] to Everyone: thanks! 09:50:12 From Þórarinn Bjartur Breiðfjörð Gunnarsson to Everyone: usually expired paste is just harder to work with because it dries out 09:51:05 From Jans Hendry to Everyone: Is that purple PCB? Where to buy? 09:51:08 From Jon [Stem Inc] to Everyone: ^ Thanks Porarinn, I hope I spell ur name correctly. 09:51:17 From Krisjanis Rijnieks to Everyone: oh the purple one is from a board house 09:51:32 From Jans Hendry to Everyone: oh 09:51:41 From Krisjanis Rijnieks to Everyone: once you learn to produce a board in a fab lab, you might want to try out one of the online manufacturing options 09:52:04 From Krisjanis Rijnieks to Everyone: that way you will be able to have additional features such as solder masks and silk screen printing on top 09:52:28 From Jans Hendry to Everyone: Ok 09:52:43 From Krisjanis Rijnieks to Everyone: for reflow it is perfect as the solder mask material is pushing the solder away so that when you do rehlow soldering, the liquid solder ends up on the pads 09:53:16 From Krisjanis Rijnieks to Everyone: so it flows off the masked surfaces onto the pads 09:54:00 From Jans Hendry to Everyone: got it thanks. 09:54:21 From Krisjanis Rijnieks to Everyone: you can make a solder mask in a fab lab uzing vinyl cutter and epoxy tape 09:54:47 From Jans Hendry to Everyone: Are we going to learn about that deeper later? 09:54:48 From Krisjanis Rijnieks to Everyone: you can export the solder mask layer from KiCad or Eagle and then cut it with the vinyl cutter 09:55:24 From Krisjanis Rijnieks to Everyone: these are extras. if you go far enough with basic reguirements, you might have enough time to explore the other options 09:56:16 From Roland Grichnik to Everyone: @Krisjanis: Do you have recommendations for the tape/foil?
