 Jan-Peter | I have stacked my first plastic PCBs | 12:07:43 |
| Jan-Peter | Artur Scholz: Are you sure that the PCBs should be 10mm apart? It seems so close together ... | 12:08:22 |
 Artur Scholz | I did clearly say 16mm | 12:14:48 |
 cajt | Just out of curiosity, why did the structure get such a complex geometry (and so many screws in sizes I don't have on stock)? Is for specific solar panels or 3d-printing? (didn't see rationale in git) | 12:44:05 |
| Artur Scholz | The structure was (almost) not changed. The screws are now Torx, because Torx is just better for fastening those small screws. But you can still use the hex screws, the dimensions are equal. | 15:13:40 |

| Jan-Peter | He really did almost say it.
I just did it wrong anyhow 🤷♂️ | 16:37:57 |
 Husseinat Etti-Balogun | It's funny how our brains read over crucial information when we're excited to do something... have you tried the 16mm spacers now? | 22:13:06 |
| Husseinat Etti-Balogun | Welcome Dipanwita Das ! Glad to have you here. Would you mind introducing yourself to everyone? | 22:25:40 |

| Dipanwita Das | Hi everyone! I'm a recent graduate with a degree in CSE. I'm excited to join this community and contribute to different projects. | 03:16:24 |

It's funny how our brains read over crucial information when we're excited to do something... have you tried the 16mm spacers now? I have to order them first. | 06:20:05 |
| Jan-Peter | Its tricky because some dealers label them as 16mm and some as x+6mm
So in this case, the 16+6mm are the right one - 16mm spacer. 6mm thread | 06:21:25 |

| leslie7238 | Hi there, we are following the LibreCube/PC104 board spec to design our PCB. According to the specs, the PCB board thickness is required to be 1.57mm. However, due to complexity of the design, we may need to use a PCB thickness of up to 1.8mm. We are wondering if the thickness of 1.8mm acceptable for CubeSat integration? Or, what is the margin in the thickness of PCB boards? Thanks a lot! | 10:09:00 |
| Artur Scholz | The 1.57mm is standard thickness of double-layer PCB. But you are free to use any other thickness (eg for multi-layer boards). The main impact would be on fitting the board stack into the structure, which can be solved in various ways (eg user shorter stand-offs). | 11:10:03 |

| cajt | Or the stack just gets a bit higher. The integrated system has to take tolerances in PCB Manufacturing anyways. Also many board houses have high tolerances for thickness anyways. | 13:16:56 |

| leslie7238 | @Artur Scholz @cajt Thank you for your comments! Yap, in LibreCube Board Spec, only the thickness 1.57mm is given, no tolerances/margin is given. It would be better to have the spec updated/improved. | 01:18:09 |

| cajt | Formally not so nice, but board thickness is not extremely well controlled, even with the same design in the same procres. The flow of the resins and position of the fibres causes some variation. +/- 0.1mm would be a low tolerance, across many baords +/-0.25mm would be more reasonable (and yet someone might want some special PCB with like 2.5mm or some thing similar). | 10:45:00 |
| cajt | What would be the highest reasonable stack? Like 6 Boards? | 10:50:44 |
| Artur Scholz | 5 boards fit in 1U, 12 in a 2U CubeSat | 11:15:13 |
| cajt | 12 boards in one stack sounds like a not-so-comfirtable integration situation. Wouldn't one split the stack in that setting? | 15:08:43 |

| average1129 | Hey everyone just joined this group, super excited. I just started my Masters in Space Technology and I've been working on network/communication software for the past few years. I'm hoping to start contributing to the python libraries related to comm/networking. | 08:15:14 |
