Hi All,thanks all for this valuable comments. I see now that I should have studiedt more before creating the PCB. I really thought its just wiring the things together!I see that the arduinix layout is much cleaner, but does it fullfill all the arguments from Alex?I will take all this input in my version 2. Many thanks again Sergio On Wednesday, 15 May 2013 02:21:38 UTC+2, nixiebunny wrote: Sergio, I see the problem. As others have said, your PC board layout may be correct for your net list, but it is completely wrong for a switching power supply. The Nixie power supply design by Nick DeSmith is a good one. Copy it exactly. When doing a PC board layout, the first thing to do is to move around all the parts so that the connecting lines are as short as possible. This takes a lot of time. I will typically spend a day moving the parts around to get a nice placement. After I do that, then the wiring part of the job only takes an hour. Also, be sure to use heavy traces for power. Those bypass capacitors next to the ICs are essential too. A PC board layout that looks pretty is more likely to work well than one with the traces spread nilly-willy all over the board. > <https://lh4.googleusercontent.com/-PsF8r0jvHEQ/UZDN7eiidtI/AAAAAAAABH4/x_mkJRi4IPU/s1600/nixieclock_v1.1_Leiterplatte.jpg <https://lh4.googleusercontent.com/-PsF8r0jvHEQ/UZDN7eiidtI/AAAAAAAABH4/x_mkJRi4IPU/s1600/nixieclock_v1.1_Leiterplatte.jpg>> >-- David Forbes, Tucson AZ--You received this message because you are subscribed to the Google Groups "neonixie-l" group.
