In a previous job, we used mask color to specify rev or phase of the product. Development was red, confirmation prototypes were blue, and mass production were green for cost reasons. Made it very easy to see what version a board was

As a 35-yr+ veteran of EE, I can always tell the level of the designer by just looking at the bare PCB.

Except on white boards, I always put a rectangular box of silkscreen, to allow writing on with a fine permanent marker - useful to note issues while inspecting/ testing, numbering etc.

Teardrops are also good for mechanical strength for larger parts, connectors etc. to avoid fracture of tracks where they meet the pad

Back when I did PCB layouts aesthetics were always important to me. It seemed that many engineers and other PCB layout people couldn't care less about the look, just get the layout done ASAP. One engineer did complement me when he said "Wow, I can SEE the signal flow!"

Been designing pcb's for 20 years now.. My motto is that if it looks good, it will work good! 😊

16:49 Green Vs Black or other solder masks : the human eye is more sensitive to green and red colours making it easier to see the copper traces under green and red rather than black solder masks. This helps with debugging especially where traces are parallel with each other. Great video thanks for sharing

Yeah, I love using inverted silkscreen for things that the end user wants to find. The user quickly learns to tune out the noise silkscreen, and just see the inverted, end-user things.

I think 0.5mm (or 0.25mm at a push/with smaller than 0402) placement grid should be a legal requirement for PCBs 😅 it makes boards sooo much nicer looking, quicker to arrange components (less options), easier to assemble… Easily the best board design tip I ever learned.

Thanks for making a video on this topic. The aesthetics bring me joy while designing, and that has to be worth atleast a teeny bit. :)

A tip: As Phil alludes, some of the aesthetic appearance tuning steps tend to come at the end of the pcb design steps. This is right when there's pressure to get the design files to the board house ASAP. To avoid forgetting one of these satisfying appearance steps, it's a good idea to maintain a checklist of items to perform at that stage. Both standard items, and any items that occured to you earlier for this specific board. And of course rerun the Design Rule Checks when done.

Another good looking thing is to use the gold plating as a font/indicator. We usually don't use silkscreen, but often the customer wants some indicators, then I place a mask on the solder layer and the same on top to have a nice shiny looking indicator.

Lots of good stuff here - thanks for sharing. My two penn'orth: I like to add silk screen rectangles and text around lower-level functional areas (e.g. regulators, filters, etc.) - I think of the person who might be repairing it in 20 years time...

I usually try and focus on adding as much symmetry as possible, if the deign allows for it. Most people seem to be drawn towards symmetric designs in general. Love the video as usual!

This is very informative and well done. Thank you.😀

I started layout on circuit boards around 1979 on a light table, two sheets of frosted mylar, rolls of 40 thousandths tape and an xacto knife! For a hobby now I use Fusion360's integrated electronics module with the 3D CAD so I can make sure my boards fit into the enclosure. How far we've come!

Thank you for all your remarkable and fruitful videos Mr. Phil 🙏🏻🙏🏻🙏🏻

Immidiately respect to UKposts video ep creators that number their videos, makes it so mich easier to find useful ones. 👍

Phil, huge thank you for your videos, just thanks to you, and your videos, I started designing my own circuit and PCB. And just thanks to you I realized I can avoid soldering it by myself, and order complete assembly. Though my own designs are quite basic compared to your masterpieces, still I feel more confident with my habit. Thanks a lot!

What a great week, two videos in one week

Thank you so much Phil. Great video!

This is one of the things I like about your boards, they look aesthetically pleasing.

Great video Great points in PCB design/fab. Thanks for sharing your expirence with all of us 👍 😀

very professional and helpful ,Thank you for sharing

Let's just all accept that we love the beautiful PCBs since the childhood when we used break open old electronics to stare at these PCBs and we just absolutely love it when we get stare at the beauty of the PCB we freakong designed ourselves. We get to be the artist we used admired since childhood. And for that my friend, asthiestics is absolutely fucking worth it

PCB layout is like town planning. Where to put McDonalds... I hate seeing old PCBs in landfill or at the dump. They're so often works of art. Even your average motherboard is replete with care, inspiration and artistic flare - and somebody probably put their heart and soul into making it real. I have PCBs hanging on my wall (single sided naturally). Sad I know but it inspires me. Good job we have multi-coloured solder resist otherwise my bedroom would look like Kew Gardens!

Tks a lot for sharing your knowledge. Subscibed and liked all your videos. Really. TKS A LOT

All the manufacturers I've ever used automatically punch the resist layer through silkscreen so you never get silk on pads.

I often spend way too much time making tracks look neat...

Nice topic! I always make sure of the functional parts, but I treat them as art as well.

David Jones's PCB Design tutorial (i think I read a while ago on your recommendation) mentions only ever using thou/mils and metric only for manufacturing dimensions. I noticed you using metric. Wondered what you thought on this topic as someone brought up with metric. On a different tangent: It depends what you are optimising for but I feel better to use fonts that are optimised for legibility at small sizes, typically newspaper fonts excel at this, century gothic is OK. Generally sans serif is a faux pas for small text when legibility is the priority. Counterpoint; Bell Centennial is a good example of a sans serif font optimised for density and poor printing used as small as 6pt, ideal for silk screen. Typically Egyptian style fonts excel. An equivalent Egyptian font like Lucida will be more legible than a san serif. Guardian Egyptian is a nice modern example of a font optimised for newspaper sized text. The grotesk style font used in most youtube thumbnails is often not great at peoples natural astigmatism leads to edges being blurred :)

Thanks for your videos🚀

Hey Phil, I have a request. It would be great to make a video on how to look for pcb design jobs. What could be the requirements or interview topics? etc.

I couldn't agree more with this and I believe any PCB designer will say they love the 'end bit' of tidying up ! and your right It gives you a bit of an artistic outlet like solder mask colours for instance. I like Matt black, as many do but I like anything Matt, my second choice would be green, I dislike red PCBs because a firm I worked for made all prototypes in red so they couldn't get out in the wild ! from then till now I consider red PCBs to be unfinished or simply wrong ( PCB prejudice ? Lol ! ) Regarding fonts only use one or two at the most as loads of different fonts look awful, apart from that it's about time we had a vid talking about this as it IS important...cheers.

Awesome video !

Thank you for sharing

I have never used Altium, but Kicad automatically takes care of most of the problems you mention. For example silkscreen on top of cover is automatically removed unless you specifically ask for it.

Great video, but regarding the grid size of not going smaller than 0.25mm how do you get the components to line up and the traces to enter the pad uniformly without making the grid smaller? Every time I use a 0.5 or 1mm grid I end up having to go smaller because it never looks quite right. Either the component isn’t lined up or the trace isn’t straight. I’m use Ki Cad 6 for my designs for reference btw.

Hi Phil, great video as always. I am a strong proponent of aesthetic PCB's. I do have a request to make a tutorial on routing in Altium. I find it very hard to route since Altium doesnt always allow me to place traces the way I want. It seems to fight me for it. And moving components after routing is a nightmare since the traces dont move with the component gracefully. Thanks

I have OCD, so this is very important to me

This is a really important aspect when designing prototypes for clients I've found. I work in the creative/event industry and the people I design for are very interested in aesthetics, even though as you say, nobody will see the tech in the actual product/event. Also, I recently made some business cards that can also play Tetris and hiding the vias under chips and between the LEDs in the 10x20 matrix - and even the routing of the tracks - was important (the card itself is only 1.6mm thick + the height of the LEDs, as the battery sits through the card - it all runs from a single ATMega328pb chip - and also shows other info and animations on the matrix depending on the mode its in :) ). Of course it helps that I'm VERY OCD when placing parts :) I also tend to place parts that need to fit through a casing on cm boundaries when possible, as it makes it much more simple to measure and cut/drill casings accurately.

Nice lecture.

Thank you

Aesthetic is appreciated when sit and debug our designed boards, on commercial dev boards this is very much applicable.

For the ground edge of the board trick what’s the fastest way to do it? Did you just manually use lines and arcs or is there like a trick to do it quick?🙂

I am doing most of your recommendations not because I am a good engineer but because I have a form of OCD:))

Glad to hear you’re a fan of Century Gothic

My latest board had a big arrow on the bottom of it, with the lettering “this board is a skeleton, do not trust what it says”. Wonder what was below it in the shared panel?

I also like the aesthetic of rounded corners, and use that for all my PCBs, but I don't really see that PCB manufacturers can't mill sharp corners, as long as they are not internal sharp corners.

I once built an ITX computer, and the tiny motherboard (Asus Z590-i) was so good looking, I just kept staring at it like a piece of art, before installing all the other components.

I think your boards would make great commercial success, I hope one day I can buy some.

how do you make vias and pads have the same color as your layer?

Note that for scoring/snap options, rounded corners should be avoided. Panelization with these methods can dramatically reduce the cost in larger quantities.

Hi Phil. I often see stitched mounting holes which are also PTH. What are you thoughts? I just assume that the stitching is redundant unless it has to do with inner ground layers or better purchase with mounting hardware.

Can you show use how to lay out a complex board (8-12 layer etc) such that the tracks aren't crossing constantly. It's seems that you have the ability to layout without crossing at all. I hate how crossing looks.

I made the mistake of having the font size so small the power and ground marking couldn't be distinguished. Looked huge on the preview

I love your videos

Its so informative video , but I hv a question, for beginners pcb designers what kind of staff they need to study to be able to design

Just checking, when you talk about silkscreen on copper around 13:20: you mean exposed copper right, and not that there is copper under the soldermask?

I've been following for a while and this weekend I just managed to get my first full signal path through my code. Now I have no excuse but to try and learn to speak "Greek". I just get lost as soon as you start speaking in Mathematics. Literally as soon as I see a w (omega) I switch off. It's gibberish to me. Sometimes I can "see" what you are doing and understand what the code is doing, but I can't understand that in the language of Maths and I just don't speak it. I'm hoping to find a library and aid my learning by me only havng to figure out what I want and how to set it up.

If I may suggest one public project as a universal PLC with STM32 with CAN Ethernet Wifi with lot of IO for Home automation programming with ST Software

I add logos on the copper layer with enig finish, is this bad interms of functionality?

Aesthetics are primary indicators of if something is going to work, work well, and be maintainable. If the producer can't make it look good, they probably struggled in other areas.

How did you get the yellow colored silkscreen? There’s only black and white to choose on their site 🤔.

Hi, I'm a beginner, I have a question, if you are working full time for a company and making a PCB for them, they are the product owners, so should I sign the PCB with my name or just put the company logo and version number?

where can i download this PCB file

Can we talk about Smile Wang from Pcbway lol

square corners should be fine with vscoring

❤

I see you removed all your designators, don't you think it would be more easy to have them at a lower font size and do add them?

👍👍

Tenting vías is not recommended because some acid may remain inside and destroy the copper.

I end up needing my pcbs to be as small as possible, and to use only components I have on hand, and I hand solder everything. All my pcbs are ~20mm2, asymmetric and ugly as hell! ;D

I picked up on a trend of putting totally useless information on boards silkscreen. For example: "WARNING: FOR EXTERNAL USE ONLY" or "NOT TESTED ON ANIMALS "

👍🙏❤

I would actually buy an aesthetic PCB (preferably populated) as art - if I come across one...

No designators in your silkscreen?

Those mounting holes rub me the wrong way - annular rings are berely there, that machining around them is wtf.

It basically is proof-of-work for humans.

I'm beginning to think that Phil has an OCD when it comes to PCB design hence why he's so meticulous. This topic is not widely talked about in the technical space. After all, PCB design is not only purely engineering but also art.
