All SMD components placed on the same side of the PCB.
This is not a "simplified version." This is the optimal solution.
| Comparison | Double-Side SMT | Pure Single-Side SMT |
|---|---|---|
| Pick-and-Place Runs | 2 (top and bottom) | 1 |
| Reflow Soldering Passes | 2 | 1 |
| Board Flipping Required | Yes | Not required |
| Component Drop-Off Risk | Yes (components on bottom side may fall during second reflow) | None |
| Carrier Fixtures | Required (trays / pallets) | Not required |
| Panelization Limitations | Limited by double-side layout | No limitations, fully flexible |
| Bulk Unit Price | Baseline | 20-40% lower |
Panelization Advantages
With all components on the same side, panelization design has virtually no limitations:
Any arrangement — maximum board utilization · Pick-and-place machine populates all panels in one run · After depaneling, each board is complete and fully functional
