Tolerances

email this pageemail this page
  1. Inner Layer Clearances

  2. We require a minimum of 0.010" inner layer clearance.

  3. Copper to Edge of Printed Circuit Board

  4. Minimum of 0.010" (outer layers) and 0.014" for inner layers (0.020" preferred for inner layers). For scoring, minimum of .015 for outer layers and .020 for inner layers.

  5. Pad Size/Annular Ring

  6. Pad size should be at least + 0.010" over finished hole size for vias and + 0.014" over finished hole size for component holes. This means the annular ring (radius of the pad) should be at least .005" for vias and a minimum of 0.007" for component holes.

  7. Hole Size

  8. +/- 0.005" Prototype
    +/- 0.005" Production default
    +/- 0.003" Production upon request 1 oz and 2 oz finished copper weight only
    Minimum finished hole size; 0.010". Call your salesperson if you required a finished hole size less than 0.010".

  9. Printed Circuit Board Thickness

  10. Overall may vary +/- 10% (Minimum +/- 0.005")
  11. Minimum finished thickness for 2-layer: 0.005" (Call if you need a thickness of less than 0.005")
  12. Minimum finished thickness for 4-layers: 0.020"
  13. Minimum finished thickness for 6-layers: 0.031"
  14. Minimum finished thickness for 8-layers: 0.047"
  15. Minimum finished thickness for 10-layers: 0.062"

  16. Inner Layer Thickness

  17. Tolerances do not apply to the inner layers of prototypes.

  18. Rout (Board Outline)

  19. +/- 0.010" (+/- 0.005" available for Production upon request)
    Note: We rout to your board size using the center of the board outline on your mask layer.

  20. Copper Trace Width/Spacing

  21. This is the minimum air gap between any two adjacent copper features. Trace width is the minimum width of a copper feature, usually traces.
  22. For trace width/spacing, we require a minimum of 0.005" for 1 oz. finished copper weight on outer layers. Premiums are added for trace/space specs less than 0.008"
  23. For 1 oz. finished copper weight (inner layers), minimum trace width/space is 0.005"
  24. For 2 oz. finished copper weight (inner & outer), minimum trace width/space is 0.007"
  25. For 3 oz. finished copper weight (inner & outer), minimum trace width/space is 0.010"
  26. For 4 oz. f inished copper weight (inner & outer), minimum trace width/space is 0.012"

  27. Trace Width/Air Gap

  28. The greater of +/- 20% or +/- 0.002"

  29. Soldermask Swell

  30. This is the expansion of mask relief over pad area. Our minimum is 0.005" over pad dimension or 0.0025" each side. Advanced Circuits will modify files to meet the minimum dimension.

  31. Slot Width

  32. Minimum 0.031" in width. For smaller width, call your salesperson for pricing and turntime.

  33. Tab Rout Spacing

  34. Please allow 0.100" spacing between your individual pcbs for tab rout spacing. When scoring there should be no spacing between boards.

  35. Silkscreen (Legend)

  36. 0.005" minimum line width.
