    hi i recently sent an order to jlcpcb for some panels, i followed your steps for the graphics as f.mask however when my panels turned up the f.mask graphics were in a silver tin finish and not the exposed copper, what did i do wrong?

    • @worriesinthedance

    • @eurorackDIY
      @eurorackDIY 2 роки тому

      So sorry to hear you didn't get back what you expected. The layer in KiCad that allows the gold (or silver in your case) to show is labeled "F. Mask". That's for the front solder mask which in the case of my boards I've selected to be black. The graphics displayed in KiCad are the inverse of that mask so where you see text or graphics will be an area that doesn't get the mask when the board is manufactured. While the copper traces are indeed under the mask, the manufacturing process at most processors puts one more coating over top of the copper, the surface finish (at least that's what JLCPCB calls it). This finish is there to make it easier to solder to the area not covered by the mask. The default for this finish is solder (either with lead or lead-free) so ends up coming out silver colored. To get the gold color you need to specify a surface of ENIG or electroless nickel immersion gold (it costs extra but for me and the aesthetic I'm going for it's worth it). The gold coloring literally comes from gold as it's the final layer of the process and specifically there to prevent tarnishing so that the board can be soldered to after a significant amount of time has passed.

    • @eurorackDIY
      @eurorackDIY 2 роки тому

      For sure, it's fine to have it be silver and make that the basis of the look you're going for. But you don't need to make all your panels the same and you can vary knobs and knob colors, solder mask color (so the overall background color) or whatever you like - that's the beauty of DIY - it can be your own personal style!

    • @worriesinthedance
      @worriesinthedance 2 роки тому

      @@eurorackDIY that explains, i did check with jlcpcb and they mention choosing a different surface finish as you've suggested, the add-on price is quite steep imo, especially since it is diy for me effectually ;) maybe ill give it a one time run and see the results for myself, I might just get swayed

      If you're talking about the version of KiCad I'm using in the video, it's unfortunately going to happen that it gets updated and will be different from videos I've made in the past. While I show some specific ways to use KiCad to create boards for modular synthesizers I'm not sure I'm ready to make this be all about that particular tool. There should be plenty of other great videos by other UA-camrs that better track KiCad's capabilities.

    Thank you for a really good tutorial! When i ordered from JLCPCB there wan an option to replace the FR-4 with aluminium. This turned out great! My gold (f.Adhes) layer turned out silver thou. Maybe that has to do with the aluminium body. IDK. But the silver is not aluminium. Any thoughts? Thank you again :))

    • @eurorackDIY
      @eurorackDIY 2 роки тому

      I'm glad the tutorial was useful, and thanks. As for using aluminum instead of FR-4 from JLCPCB, the layer that I use to get the gold coloring is what they call the "Surface Finish". There are three options they offer for that, two are solder masks (with lead and lead-free solder) and the third is ENIG or "electroless nickel immersion gold". It is only the ENIG finish that will give you a gold color for that layer. Unfortunately, they don't offer ENIG as an option when you choose aluminum boards. The inability to get the gold for my front panel graphics is why I've stuck with FR-4 for my designs and so far I've not had any problems using it. JLCPCB upgrades their processes frequently so perhaps someday this may become available.

    • @eurorackDIY
      @eurorackDIY 2 роки тому

      I have not tried it as it doesn't offer the ENIG surface finish (at least yet) which means I don't get the gold graphics which I guess I'm both willing to pay for and forgo the option of aluminum. I've been completely happy with FR-4 as a material for my front panels and so far have seen no drawbacks from using it for that purpose.

    Instead of making yourself suffer, setting your reference point and board edge boundaries, here's a suggestion. Set the grid to 5mm and set your reference point. Then select the tool to draw the board outline and set the first corner on the reference point. Change the grid to 0.5 to scan down to 128.5. Change the grid to 0.2mm and scan across to 9.8 mm. Change the grid to 0.5 again, and scan up again, until you reach the same horizontal line you started from and then on to close the rectangle.

      Getting features to match and placed exactly where you want them always seems a bit difficult in KiCAD so I'm looking for new suggestions. I'll give this a try on one of my upcoming projects.
