I don't think it's good industry practice to do it this way. As a general rule, don’t put component values on the silkscreen, just the component designator.
It might make it easier for beginners, but it will be difficult when it comes to troubleshooting and articulating which component is being referred to. |

I am arguing that I feel it is exactly the opposite for DIY stuff.
Think about this -- how are you supposed to read the resistor designators (ie: R1, etc.) once all of the resistors are installed? They're covered up by the resistors. You still need the component designator overlay in the build documentation when you have to troubleshoot, so may as well forget it all together on the PCB when it could make room for something actually useful during assembly.
Thus, there is almost no reason to prioritize component designators over parts values when it is a human being assembling the circuit board.
Nobody cares what specific 100k resistor in the schematic it is that they are installing, when they have 42 resistors to install! They just want to get it over with ASAP and get onto making sounds!
I think you should put the designators in the build documentation (a good component overlay that the user can print out, should they need to troubleshoot/whatever). Assembly is so much easier and faster with part values on the board, and means you do not have to muck around with printing stuff out/having a computer beside you if you don't want to. _________________ hexinverter.net -- Shop DIY projects and modules for modular synthesis

Hex
i'm hearing you on this, your doing small runs for folk of different skills levels, i personally find it frustrating when i'm faced with no component values on the silkscreen, i understand that it may lead to other complications. But sometimes i feel i'm more likely to make a mistake when there is no component values on s/screen and it takes longer, it's helpful to have as much info as someone is willing to provide when building up modules. |

I don't care if you put component value or D1 - D29 or silly names like ralph, bob, and sam!
I do, however, want at least 2 pcbs.

The old Postman came knocking at my door today!
Unfortunately, I have 4 exams over the next week and probably won't get time until after to assemble and test them all before I can start shipping them to people Sorry guys. I still haven't made a BoM for this either! Argh! I need more time!
Will keep you all updated!

I got an idea
so will need 4 boards now.

Haha.... No only 8 but i was thinking complex envelopes for the moment unless i go really insane.
I am working on a CV "any pattern" bidirectional 8 way switch.
[ it is possibile to go 'n' variable I/O's with the architecture employed]
not sure what the max could, be, havent calculated that .
anyway quite a stupidly large number of switchable I/O's would be possible in theory.
this will form the basis for a matrix sequencer eventually _________________ In an infinite universe one might very well

I just finished testing the Postman EG PCBs and everything is a-okay!
Feel free to order from my shop! I restocked a bunch of other stuff as well.

not many times when you hear that indexes make processes slower but i guess i agree in terms of populating boards
i think at a minimum there needs to be a diagram in the build docs with the part index overlay corresponding to the schematic - that makes debugging circuits a lot quicker _________________ problemchild

Sorry, forgotten I had posted here. Yes, it may seem idiot proof to print the values on the pcb. The advantage may become apparent when later you realise one of your components needs to change value. |
