 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Trivial, yes but there's just something satisfying about this:    |

I tried it but we didn't get along. If you start doing things like moving traces around or deleting them once the teardrops have been applied they become a track plus two triangles, which have to be deleted separately. You can remove all the teardrops at once but not individual ones. I'm flippin' rough, me. No niceties. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I went through that, Mick but I have mastered it and now it's 2nd nature. Not a hassle at all. Probably not important in this context but I just don't like abrupt transitions. Comes from machine designing, I guess. |

Phenix, PCB manufacturers do not like this:  Volhout PicomiteVGA PETSCII ROBOTS |

The pointy bits? Do they reject the design or do they make changes? |

Pointy bits can cause the copper to peel during etching, you tend to get bad edges. Also watch out if you are running parallel tracks and there is a miniscule area of ground plane between them - it can get etched away. In fact it usually doesn't matter, but you might be affecting the ground plane in some cases and lose a connection. Whether a design gets rejected depends on how good the checking is, I suppose. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Do you use ground-planes, Mick? I see lots of boards where there aren't any. |

Almost always. Now I usually use the top layer as GND. That way it's easy to get a connection on all the components anywhere on the board, even on SMD components. I often use the top layer for 5V traces too, as they tend to be fairly large. The bottom layer can be different and I've used it in various ways. Sometimes it's good to connect it to 3V3 for easy distribution, other times GND to get round awkward bits, other times just floating (although I prefer to use it for GND if possible). I take the ground plane off on both sides where I want to put an antenna on a module or, usually, where I want to put mains-carrying components because I want electrical clearance. PCB manufacturers like ground planes as they require less etching. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Hi Phenix, Groundplanes contain a lot of copper. As such they are typically low impedance. And therefore it makes life for a designer a lot easier. You do not have to think about return path (star ground) that much. Except in RF and high power design. Just think about the audio equipment from the 70's and 80's. Single sided phenolic boards, cluttered with ground traces to feed everything back to the one start ground. Volhout Edited 2024-12-05 23:54 by Volhout PicomiteVGA PETSCII ROBOTS |

Thanks guys...I got rid of the pointy bits  |

One should never overlook the damage that can be caused by pointy bits in the wrong places. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
