Board size won't come down? Too many components to fit? Single-side already maxed out?
Try double-side.
| Comparison | Single-Side PCBA | Double-Side PCBA |
|---|---|---|
| Component Layout | All on one side | Both sides |
| Board Area | Large | Can be reduced by 30-50% |
| Component Capacity | Limited | Doubles |
| Pick-and-Place Runs | 1 pass | 2 passes (top and bottom) |
| Reflow Soldering Passes | 1 pass | 2 passes |
| Through-Hole Soldering | Wave soldering, one pass | Selective soldering / post-solder |
| Process Complexity | Simple | Complex |
| Bulk Unit Price | Lower | 30-80% higher (but smaller board, smaller enclosure — total system cost may be lower) |
Specialized Quality Approach
We don't claim "zero defects." But we admit: the most common mistakes are reversed polarity and wrong orientation.
So we focus our energy on: first-article verification + dual-operator confirmation + feeder error-proofing + orientation photo documentation.
Other factories treat these as "normal waste." We treat them as "must-stop points."
