Routing and Placement Initiation

flux

I've made a plan, and started work on it.
Place components
Set board size
Routing constraints
Run design checks

Started implementing a plan

#Goal

- Initiate PCB placement and routing for the current 9V battery-powered 1 Hz 555 LED blinker project, ensuring a compact, hand-solderable design by organizing the placement of critical components and achieving complete net routing on a 2-layer board.

#Implementation plan

1. Verify Board Setup

1. Inspect the existing PCB layout to confirm board dimensions, stackup (default to 50mm x 50mm, 2-layer if not set), and unrouted nets.

2. Confirm the presence of all through-hole components (555 timer, resistors, capacitors, LED, switch, and battery connector).

2. Component Placement

1. Organize placement by grouping timing components (555 timer and its associated resistors/capacitors) together.

2. Position the red LED in a visible area.

3. Place the on/off switch and battery connector at accessible board edges with generous spacing for hand soldering.

3. PCB Routing

1. Route power and ground nets using appropriate trace widths and clearance, ensuring reliable 9V power distribution.

2. Route the remaining signal nets (including the timing connections) with auto-routing, ensuring no airwires remain.

4. Verification

1. Run layout and ERC checks to identify any DRC issues such as airwires, overlapping components, or missing footprints.

2. Iterate on placement or routing as needed to resolve these issues.

#Success criteria

- The PCB layout is sized correctly (default to 50mm x 50mm if not previously set) and features a proper 2-layer stackup.

- All critical components are logically placed with proper spacing for hand soldering.

- All nets are successfully routed with no remaining airwires and pass all DRC/ECR checks.

Inspecting chip overlaps

I need to check for overlaps, probably starting around U1.8. There doesn't seem to be any timing near U1.6, and I wonder if the left vertical VCC could be related. Maybe VCC C3.1 directly relates to x3.82, y5 to 3.8, potentially overlapping with U1.6. I'm considering that the second trace from U1.8 starts at 3.82, 3.8, and maybe even matches the first trace. I think I need to inspect the full board for any overlaps around U1.4.
