Is there any /diy/ guide for beginners who want to design their own PCBs for first time?
I want to know this too
>>2968047It depends where youre coming from.Got a solid understanding of electronics?Download KiCAD and do the first project that comes to mind. You'll stumble upon the 'PCB design' specific things along the way and just read up on it, be it power, HF, EMI, thermal or whatever else PCB specific things there are.As someone who has no idea about electronics? Read Horowitz The Art Of Electronics first. Once you understand breadboard or perfboard a few things and then go to the step where u dl KiCAD.
Oh and... BRO WTFBURN IT WITH FIRE NOW
I just use easyeda, simple as drawing the schematic in the site, click on "make pcb", move around the components so they fit nice, then click on auto route.
>>2968047Thread I started here >>>2962509It was my first PCB design.Learned EasyEDA from scratch and then I went down the rabbit hole of impedances and signal integrity.Find something you want to make or upgrade.Get an old Computer case and update the IO PCB like I did for example. I haven't tested my work yet as I screwed up and needed to reoder the PCBsBut finger crossed it will work right out of the box.
Just figure it out Be prepared to fuck it up six million fucking times though. Get a lazer printer, blue toner transfer paper, ferric chloride, copper clad board and an old iron and just fly at it
Idk how well the ferric chloride works for super fine pc parts but for this univibe thing it seemed to work breddygud. This is the smallest tolerances i have fucked with
>>2968284
>>2968283lmao why turn your workstation into a toxic waste dump, just order the $5/10 pcb from jlcpcb lmao nigga what are you doing
>have compoenents>know where they gotta go>draw lines between them until they stop overlapping>pay 5$ to have it made for you in china and shipped by airsimple as but even then>don't even bother not overlapping>just pay the extra 2$ for a multi layer pcb>>2968283my landlord did his own PCBs at home and it did not look like this. this anon is just a nigger and even had to pose extra "tools" to increase the niggerism (you should not be using a file, iron, radio, or fucking driver set to make PCBs)
>>2968047jlcpcb and easyEDA is what I use. I never bothered with making circuit boards before I used this company. I've made all sorts of stuff since.too bad it will all be inaccessible when china invades Taiwan in the next year or 2.
>>2968057it's an stm32, there is nothing wrong with that on a low frequency board. That shit only matters on GHz and even then it doesn't matter as much as people say.>t actually works in robotics and develops pcbs at multi GHz range
>>2968459basically only matters for high end rf, it's all about the inconsistent impedance at the corner.also, high current stuff, but we are talking like super high current where the trace will see like extremely high temps and like 400+ amps. then don't have anything but obtuse angles.
>>2968369>even had to pose extra "tools" I dont think you ever made your own pcb's at home. You most definitely need an iron to transfer the prints to the copper clad (when not using uv transfer film) and you then require a file to blunt down the razor sharp cuts on the copper clad so you can handle it without cutting yourself. He is using toxic chems (ammonium phosphat is weaker but much safer) in the dirty shed and not in the kitchen which is a positive..has radio to pass the time filling those 100 joints on the board, I dont see any problems here and his end product is pretty good.
>>2969085Yeah that guys full of shit. My setup is pretty cave-man but it works. What you got there? Some audio amps? I also like the boards your using, where'd you source those from? They have a "retro" vibe to them compared to the copper clad stuff my supplier has.My UNI-vibe thing is going pretty gud. I just got the chassis all done up. I repurposed some broken japanese radio for the case/chassis
>>2968459It never 'doesn't' matter. Also noise is always present and sure, most of the time the little noise there is wont harm a thing. Until it does. And also sensible layout simply means the final product will be less sensitive to noise, so it can operate reliably in a higher EMI environment.But all that don't matter: It's ugly, it's not right, you shouldn't be doing that. >t. works as communications front end / radio head dev
>>2969094The copper clads were from ebay - china, i think it was just an older cheaper batch i was using, they varied in color, it was just what arrived that one time.I dont find them desirable because it might have an effect when applying silkscreen / uv paint but i never tried. The amps parts i am using are an older obsolete tda2030A , i just reverse engi the traces from those 2 dollar kits also from ebay and made my own board and sourced heat sinks.. they work pretty well and sound alright for what it is.Univibe looks crazy, so many parts, pretty good drilling as well, i would of been more impressed if you were rebuilding the actual radio though :D. I found this at a flee market in east euro last year.
>>2968369>this anon is just a nigger and even had to pose extra "tools" to increase the niggerismhe looks legit, only concerning thing is that coffee mug next to the batch tray
>>2968056solid first option. just beware of downloading random component libraries. they are a pain to maintain in actual jobs..
>>2969158see >>2968461it literally doesn't matter for low end boards, i'd rather people build shit sub-optimally at all than have them follow esoteric engineeringif you came at me with but 45's give you more space, i'd have agreed, but it only matters to you and me and other in rf/highpower
>>2969737Again: It never doesn't matter. It is just that in many applications you get away with it because your noise floor is so far away from what you're doing, you just have the budget.But you will reduce this budget. No need to sweat about it but just don't up your noise floor on purpose.It just makes it more likely - even when it's entirely unlikely - that you find your noise budget isn't all that much after all.It also means whatever you're making can operate in a bit noisier environment - even if you don't expect it to ever need to.It's like building a house and you get strength in load bearing walls for free, without downsides, but you choose to forego it and go with something weaker at the same cost. It probably makes a fine and stromg enough house. One will go down in a 5 and the other in a 6 earthquake. And there's no earthquakes in your area.
>>2969739You are one autistic faggot
Dave Jones' guide is a pretty good place to start.
>>2968057So what's the right way then?
>>2971580It's probably fine for what you're doing but generally avoid sharp corners for EMI reasons, because you can accidentally make something that's like a little horn antenna, and historically to avoid acid traps in PCB fabrication, though that's not as much of a concern at well-controlled modern fabricators.
>>2968047You basically start with a big, fat ugly pcb, then you shrink it down with more efficient pathways and layers every time.
>>2968057It doesn't matter on a low bandwidth board, smooth brain. So cute to see people like you spend hours "making it pretty" and the only measurable difference is that your boss had to pay you for that extra time you were indulging in pointless busywork to calm your autism. Modern manufacturing methods also don't have issues with acid traps in sharp corners like that.
>>2968422>too bad it will all be inaccessible when china invades Taiwan in the next year or 2lmao nc try chang
>>2971580its just bad jujuthere is no real reason other than avoiding comments from people trying to show off how much more they know than youetching wasn't ever an issue unless you were routing 3thou track, ironing toner transfer and etching in your bathtub.emi is a 'black art', its an excuse you pull out to cover something ugly because nobody can call you out on it. not the other way round outside of general ground plane-ery.>why have you done that? oh...for uh..emi...yeah sure we tested it...weird huh...track angles should be obtuse. you break a 90 into two 45s. a tee should be something like three 120s which is mental to do in cad or just a 90 off a 180 but you fillet the corners.you just do. its just 'how its done'
>>2973630>So cute to see people like you spend hours "making it pretty"on the other hand there is no harm in making it look nice.there are two rules to follow in life:1) if somethings worth doing, its worth doing well2) never waste time fixing something that worksyou might find these contradictory but they aren't, as long as you do it right the first time. which takes practice.certainly its worthwhile being neat because it is much simpler to inspect/debug/fix. more so in a circuit diagram of course.
>>2973633Sure, especially in schematics I rather spend some extra time to make things neat so it's unambiguous which label belongs to which part, which is my pet peeve when I have to decipher sloppy schematics that take extra work to understand. My point was just to not get bogged down (too much) by minute details that do not matter to have more time for things that matter like supply-chain management (by choosing the right components/packages, etc) or any of the things that go into bringing a product onto the market (legally).I have colleagues that spend 10x the time I need to finish something because they can't distinguish between sensible fiddling and fiddling to calm some OCD or tism and it drives me crazy. For example, they shift around cosmetic elements like company labels before setting the isolation distance in HV circuits and then take days to manually "fix" their mistake with a dremel and hotglue. And that was a circuit he designed so why on earth didn't he know which trace has a high potential referenced to GND and therefore needs to be isolated? Or, spending time on useless shit before labeling every connector WITH THE INTENT of the connector? It's a "trigger output"? Then why isn't it labeled as such on the PCB or at least in the schematic? I had to redo multiple designs that I inherited because these basic rules were not followed to the point I think he was there to sabotage us. I refuse to believe that anyone can be so fucking stupid.
