SMD Timer Specs


I think we have a big backlog of cumulative crud here. I think we might want to go to a version 2 with same schmatic and physical layout but start fresh on routing with a big emphasis on manhattan layer approach. Can you generate a fresh new project as Precision Burst timer SMD version 2? we want identical board dimensions and connectors and component positions but ditch all the copper traces. keep documentation too. we just want a fresh start on routing. Does that sound like a good idea?
Yes—this is the right recovery strategy. I’ll create Precision Burst Timer SMD Version 2 as a clean project, preserve the schematic, documentation, board geometry, connectors, holes, silkscreen, and exact component placement, remove all traces/vias/copper routing, then verify the new board is ready for Manhattan routing.
The new project is created: Precision Burst Timer SMD Version 2. The clean recreation is now copying the schematic, files, mechanics, labels, and exact placement while explicitly excluding every trace, via, and routed-copper artifact.
Yes—the Version 2 approach is appropriate.
Created Precision Burst Timer SMD Version 2 and completed the clean-recreation task intended to preserve:
  • Schematic and netlist
  • Project documentation
  • 160 × 75 mm four-layer board
  • Exact component placement and connectors
  • Holes, keepouts, labels, and silkscreen
  • No PCB traces or vias
  • Manhattan routing requirements for the fresh routing pass
Further independent verification is pending because no ACUs remain. Before routing, verify the new project has four copper layers, matching component placement, and zero routed copper.
