PCB Panel Utilization Calculator
From board size, panel size and spacing, get the number of boards per panel and the area utilisation — check it before quoting or designing V-cuts.
Key points
PCB Panel Utilization Calculator: From board size, panel size and spacing, get the number of boards per panel and the area utilisation — check it before quoting or designing V-cuts. Formula: n = ⌊(L+spacing)/(l+spacing)⌋ × ⌊(W+spacing)/(w+spacing)⌋. Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Quotes are based on panel area including rails, so low utilisation is wasted laminate; rotating 90° sometimes fits another row. Keep panel edges under 250mm (a limit on some lines); extreme aspect ratios distort V-cuts.
Inputs
n = ⌊(L+spacing)/(l+spacing)⌋ × ⌊(W+spacing)/(w+spacing)⌋Calculation model (updates with parameters)
| Array (length × width) | 3 × 3 = 9 PCS | |
| Area utilisation | 56.3 % | 180.00 / 320.00 cm² |
| Usable area | 190.0 × 150.0 mm | |
| Remaining strip (along / across) | 36.0 / 26.0 mm | |
| Rail area per board | 1555.6 mm² | Rails and gaps shared across the array |
| Rail-to-board area ratio | 77.8 % |
Engineering notes
- Quotes are based on panel area including rails, so low utilisation is wasted laminate; rotating 90° sometimes fits another row.
- Keep panel edges under 250mm (a limit on some lines); extreme aspect ratios distort V-cuts.
