PRODUCTION DATA
Table 9-2 shows the layer stack-up and copper weight for each layer. Small subplanes are allowed on signal routing layers to connect components to major subplanes on top/bottom layers if necessary.
| LAYER NO. | LAYER NAME | COPPER WT. | COMMENTS |
|---|---|---|---|
| 1 | Side A—DMD only | 1.5 oz | DMD, escapes, low frequency signals, power subplanes |
| 2 | Ground | 1 oz | Solid ground plane (net GND) |
| 3 | Signal | 0.5 oz | 50-Ω and 100-Ω differential signals |
| 4 | Ground | 1 oz | Solid ground plane (net GND) |
| 5 | DMD_P3P3V | 1 oz | +3.3-V power plane (net DMD_P3P3V) |
| 6 | Signal | 0.5 oz | 50-Ω and 100-Ω differential signals |
| 7 | Ground | 1 oz | Solid ground plane (net GND) |
| 8 | Side B—all other components | 1.5 oz | Discrete components, low frequency signals, power subplanes |
