Does It Make Sense To Hand Make Printed Circuit Boards? 196

      How often do you need it within an hour? If you're prototyping, then breadboards are usually fine. I'm a bit surprised that this is news: it was the advice almost ten years ago last time I did anything that required producing circuit boards. If you actually need a PCB, they're cheap to get professionally made and delivery is often next-day (or longer if you want to pay even less). Only make your own if speed is far more important than quality, and your time is cheap.

      Of course, that assumes that you're making a thing because you want thing. If you want to hand-print PCBs because you want to learn a craft as a hobby, then by all means, do so and have fun!

          I haven't found their one-off boards to be all that inexpensive either. And then there is rework.

          And the answer to the submitter of the article is that yes, it makes no sense to hand make PC boards. Nor does it make sense to make things at all. Just be a good consumer and purchase things to keep the economy strong.

            I dunno, I have looked at making pcb for projects, and mostly concluded that the time and cost to get started, chemicals or equipment etc wasn't really worth it. I think, in the end, it depends what your goals are.

            If all you make are one-offs, and want to iterate quickly, and do a lot of it, then maybe it makes sense for you. If you can't do prototypes on breaboard or other (I like breadboard layout PCBs myself) then maybe it makes sense.

I was working on a home automation project, perfect example, because once my design is fully prototyped, I want to send off and have a bunch of them made, because I need at least 2-3 for each room of the house.

              I am not making those pcbs by hand, and I don't make pcbs by hand now, so, it really doesn't make sense for me to start.

              For certain, the more boards you need, the more sense it makes to have a board house do them. The cost per board plummets.

        There's no doubt that a professional board house is a great thing, and I have no problem ordering something 3 weeks out for a project where I carefully build and select parts, but not all my projects were like that. Just the other day I made a board for someone who needed something the following week, except all the suitable components in my parts bin were surfacemount. I couldn't breadboard that, at least not in a way where it would last more than a few days.

        Try to do touch-related stuff on a breadboard. I dare you. Even if you do the actual sensor on a PCB, the parasitic capacity on the various wires will drive you nuts, not to mention that you have to painstakingly ensure the key wires don't run to close to each other, to cross each other and $deity help you if you should dare to move the board an inch.

        Another thing you do not necessarily want to do on breadboard is some of the more timing critical SMD shit. No, breakouts are not always an option.

        Considering how cheap the various parts are by now and that you can actually (some equipment, skill and training permitting) go from design to ready-to-test board in about an hour or two, depending on how complicated your design actually is, this means that yes, there IS still a reason to do your own PCBs. I prefer to test on breadboard, too. But there are a few things you simply can't do on it.

      There are also those chain-link boards that you can build on if you need a quick simple prototype. That's an easy way if you just want one or two circuits for your personal use. Etching a board from scratch is often quirky since you discover that you need "yet another component" that you didn't plan for.

      If you have a good circuit that you have tested then you can use Eagle to cad it and order more boards if you need a small series of devices.

      Been working in electronics for >30 years.

      If all you need is a simple PCB (even 2-layer with plated-through holes is not that difficult) with no silkscreen or soldermask, and you're willing to have the chemicals and a PCB drill press with appropriate PCB drills on hand to do it, then it's very convenient. If you want silkscreen and soldermask, then it's going to be fairly time consuming and require quite a bit more equipment. If you need more than 2 layers, you're having a fab house do it for you, unless your need is so frequent and regularly urgent that you can justify the huge expense; at this point you are a fab house. Of course in this day and age, you can build almost anything you want and never have a single through-hole on a PCB (with the exception of vias); if it's a single-layer board then you don't even need vias in the first place and are just etching; if you're willing to put up with the relatively low-quality results, there's the toner-transfer method. As with most things it all should be dictated by need. Unfortunately governments would just as soon take everything that's not a common household chemical out of the hands of common citizens, so I'm not very surprised that there's someone trying to discourage people from manufacturing their own PCBs.

    Well, he has got some points... i too hate making my own PCBs (i'm not a young enthusiast anymore).
    Most of what i make are only prototypes useful to me only and it is a huge waste of time to:
    1) create the layout via software (maybe i also need to create my own components before because i can't find a library with all the ICs/components that i need)
    2) go through all the lengthy steps to make a real PCB out of it
    3) get rid of the chemicals once done paying attention to not ruin anything (i ruined a whole wall one day when i was a teen at my first attempts...)

    There is a good, although a little bit forgot, alternative though... it is called "wire-wrapping".
    Yes, it is not as beautiful as a specialized PCB, but if you have the correct wires and tools it becomes quite a fast process.
    You don't need to use any software for the layout. Did you f*ck something up? No worries... just unwrap and fix the mistake! It is strong enough to be usable in real-world scenarios.

    Of course, if you need to make several copies of your board... then the PCB is the way to go. But if you only need one damn copy or you are just prototyping... then wire-wrapping makes a lot of sense.

      I don't make my own PCBs. I do surface mount stuff and I like going for small sized. Lots of tiny vias, tiny component pitches, double sided, and of course a solder mask.

      I know people who do make PCBs and they of course use it for big fat coarse things. You can do coarse pitch surface mount without a solder mask. That removes the need for holes, too and if you're size is large you can get away with single sided + a few jumpers too.

      - Drilling the holes dead center

      Etch a dot out of the middle of the pad. The drills self-align.

      - No plated through holes.

      or electroplating: []

    There is a strong sense of accomplishment if you are able to do things from scratch, or closer to scratch, where you are involved in more of the process. Saying I need a board with this spec to a vender and get an overnight shipping, vs. actually designing it yourself, printing it out.

    Efficiency isn't always the goal. Efficiency is boring, because it is about standardizing the process, it is about taking joy out of learning and just focusing on mass production. Building experimenting and learning have value as well. If you make your own board you get a good feel on how things are setup and working, if there is a problem you can more easily diagnose problems, and you really learn what is happening.

    Of course if your boss's Business school didn't cover Business ethics in nauseum, like mine did. that may not be the best argument. However you can bring up the efficiency of being able to print multiple per day allowing your development time to increase as you can try multiple versions per day, and the cost of man hours will be less than the cost to of the equipment.

      I second the toner transfer method. From the comments here, it doesn't appear to be anywhere near as popular as it should be.

      It works great with through-hole and surface mount devices, it requires no more special equipment than an $8 (clothes) iron from Wal-mart, and 2-layer boards are no problem. Not exactly easy, but certainly not hard either.

      If anyone is interested, buying a bag of "transistor sockets" off ebay is a good investment. They are solderable hollow tubes with a lip on one side. You press them in and solder to both layers and have a very robust via. You can solder and unsolder a leg there without disturbing your via.

      To be honest, I don't do it very often any more. I think I do more PCBs by hand with a sharpie now than I do using laser toner, but that number is small too. I rarely need a board right away, and I very rarely need just one board. For me, I tend to need a half dozen of something, eventually. Like 12v battery pseudo-UPS boards for my home's Raspberry Pi sensor network, or G-M tube alarm boards for a vehicle fleet.

      I tend to design the PCB directly, then build the prototype on a solderless breadboard using the netlist, feed corrections back to the design, then send it off for fabrication with oshpark.

      To do that, you need a good collection of SMD to 0.1" carriers. Carriers for most packages are readily available, but I've had to make a couple myself (by drawing up the footprint and pins and sending it off for fabrication).

    But he also wrote a more serious column for Car and Driver. He once talked about the decline of American motor cycle industry. Famous names like Indian Chief etc and how they all foundered. Basically they produced machines which were difficult to maintain at good condition. Every three thousand miles people had to disassemble the cylinder head and decarbonize them and reset the valves and timing etc etc. The honchos in the companies were proud their customers like to get their hands dirty, they like working on these engines. Jay Leno said, "no, we don't like messing with these engines. We want to ride and have fun. But it was impossible to get good performance without doing all these things. We were forced to do it because your engines were crappy". When Honda and Yamaha started making reliable machines that delivered good performance for long times without these messy requirements, they just ate the lunch of the old style American motorcycle manufacturers. Only Harley survived, but it was touch and go for even for them.

    People like making things that work. Ages ago the only way to do it was to make your own PCB. Now a days with one day turn around, most people would like to outsource making the pcb to make sure there are no accidental contacts, no mistakenly erased and redrawn line not making full contact, making sure all the holes are drilled all the way through and there is no delamination etc. Hand made PCBs are the equivalent of your motorcycle rider decarbonizing the engine head instead of riding fast on the wide open highways of America.

Maybe people disagree with the logic, or have different goals. Maybe they want to simply do something somebody else thinks is irrational.

      I had enough lectures when I was a kid. I'm grown now and don't usually put up with it when people lecture me. (But I try to keep my emotions in check and not get in a big fight with them; inst

    They just get fewer. A decade or two ago, doing your own PCBs was pretty much a requirement if you wanted to work with PCBs and wire-wrapping or pre-made hole boards were not cutting it for you. Today, for most applications you can easily and rather cheaply buy PCBs that are usually superior in quality and also usually more likely to work as designed.

    There are a few reasons I still do my own PCBs from time to time. Mind you, the applications get fewer and I think the last time I actually etched one has been at least 6 months ago.

    - You wanna.
    Always a good reason. You want to do it because it's for something special, maybe a gift or something where hand made from start to finish actually means something. Sentimental value and all that. Also, it's fun. At least the first couple dozen times, then it just gets boring.

    - Security/secrecy reasons.
    There are always those designs you can't give to someone else. This is less a concern for most people, but there are applications where I certainly wouldn't want the design to go to some Chinese company before I can present it at the next Security Conference. Because I wanna make the speech. ;)

    - Time
    Yes, overnight is possible. Expensive (around here overnight costs upwards of 50 bucks for a simple PCB), but possible. Still sometimes too slow if you need it NOW. Or if you can't wait the 4-6 weeks that the budget price could get you. Because ...

    - Some designs can only be tested on a PCB
    Especially touch designs are extremely hard to test sensibly on a breadboard because their behaviour depends highly on the layout of the PCB. Other times you're running into timing issues if you're working with very fast switching signals. Breadboards simply don't cut it with all applications you may encounter. More and more "modern" designs (wireless devices, PC components, etc) can hardly be remodeled on breadboards.

    As soon as the design is done and I need a batch of PCBs, there is no question about whether I want to do them myself or whether I want them to be done by someone who can crank out a few dozen per batch. Designing can actually still mean etching your own. Not as much as it used to, but there are still applications that give you an excuse to indulge in your rubber glove fetish.

    The beer-free tools for PCB creation have become incredibly good recently, with the exception of autorouting which is still not so great at the inexpensive end of the market.

    Small-quantity PCB services are ridiculously inexpensive at often only a few dollars per board, delivered.

    Component pitch has shrunk to the point that making fine lines for most chips is really hard with hobbyist etching tools. Forget vias.

    So when are DIY PCBs useful? Maybe with single-sided surface mount boards that have medium-pitch components when board quality isn't so important, and you need it in hours, not days-to-weeks.

    When does that happen? Never, for me. Really, never.

    Add in the storage and surface areas required for the chemicals and processing, the setup/cleanup time, the toxicity of the chemicals, and there's a very good reason I have not ever, not once, even considered making my own PCB.

    When I need to prototype circuits, point-to-point works really well, and using SMT adapters that are also ridiculously inexpensive. And even then, the battles you have to wage with noise coupled with the really inexpensive costs of professionally-made boards make it almost not worth constructing point-to-point (and in my experience, breadboards universally suck).

    So should you make your own PCBs? If the making of the PCB isn't an end until itself for the pleasure of constructing the board, then the answer is, "no." If you like playing with resist layers, electroetch, and stuff like that, then sure. I mean, you could wind your own resistors, too, if you really wanted to. And there's a fellow who makes his own tubes, too [] (he's amazing, and I admire the skill). But buy your PCBs, don't make them.

    Making your own circuitboards is almost never the best option. But making your own cloth with a hand loom is almost never the best option either, and people do that for fun all the time. If you're taking advice from a Hackaday author, you're probably a hobbyist, and you can hobby however you want to.

  • Does it make sense? Not really. As the HaD author pointed out: creating your own boards is more hazardous, offers fewer options for multilayer boards, and is less precise.

    On the other hand, we are talking about HaD. If the point was to get a device that does what we want of it, we could buy almost anything off the shelf and sites like HaD would have very little rational for existence. More critically the environment of learning, creativity, independence, and (insert your motivation to make/hack/DIY) wou

    I don't do much of this anymore, but I have designed hundreds of commercial boards and likely into the thousands of prototypes.

    In the late 90's people used routers and crude lithographic techniques; these got better, but the online services scale nicely, and if you add up all the costs, it's almost insane to try and do it yourself. Why?

    For entertainment purposes - that's different - but there hasn't been a commercial case for some time.

    In fact, they're so cheap now, what hands on work I do, I just spin a PCB even for prototype purposes.

  • IMHO, one big missing piece to ultra-short-run production of electronic products is the ability for a DIYer to make production-quality enclosures in small quantities that aren't stupid expensive. I had (and still have) high hopes for 3D printing to solve this but current technology is slow and prone to mid-print failures. Plus, the results are lacking in appearance of a finished product.

  • How about the various circuit printers that are coming on the market now, like the Argentum or the Voltera? They're not cheap ($1500-2000), but they're probably a lot faster/cleaner/more precise than trying to etch it yourself. Voltera is capable of printing pseudo two-layer PCBs, since it has both a conductive solderable ink, and an insulating ink ink: when a trace needs to cross another, it uses the insulating ink to create a bridge, and then prints the second trace crossing over the first.

  • ... then you may as well outsource your PCB creation.

    But I see the factor of a delay as less of a matter of whether or not one *NEEDS* to have it done quickly and more simply a matter of whether getting it done right away is simply something that they might *want*.

    But what would bother me a lot is if people didn't have a choice... or if any so-called choice was actually a non-issue because only one of the options is actually both practical and readily available to them.

  • The guy who said this seems to be disconnected from the "maker" world. Amateurs make stuff in the full knowledge that it would be cheaper and faster to buy a ready-made pruduct that would (probably) have more features, be more reliable, DEFINITELY have a better quality enclosure and in all likelyhood be smaller, too.

    But that's not the point. Amateurs make stuff: electronics and software because they like it. They know that there are alternatives that are better but there's no fun in that. There's no satis

    Calculus– Use pencil and paper. Lots of paper.

    Circuits –Yes, bread-boarding is fine, but when you want to prototype, tightly integrating the components, w/soldered connections, then you should go through the process and do it for yourself. At least once.
