Artwork checklist

Minco strongly encourages customers to use the artworkchecklist provided. If you answer 'yes' to all the criteria, your art- work will probably not need adjustment. Conductor width
Is artwork conductor width:•at least 0.001" (25µm) over the specified minimum for unplated 1/2 oz. (18µm) Copper?•at least 0.004" (100µm) over the specified minimum for unplated 1 oz. (35µm) (or thicker) copper?•at least 0.005" (125µm) over the specified minimum for platedcopper? Note: Depending on the size/complexity of the circuit, the criteria may differ. Dim e n s ion s

•Are all features of letters and symbols at least 0.010" (0.25mm)wide?•Are letters and symbols clear of conductors and borders? Is artwork conductor space:•at least 0.001" (25µm) over the specified minimum for allunplated copper?•at least 0.002" (50µm) over the specified minimum for all plated copper? Bord e r a nd cutout s
•Is there a trim border (part outline) on at least one layer?•Do nominal borders allow for tolerances in the table on page 10? Conductor routin g Non-wirin g ho le c lea r a nc e
•Are conductors perpendicular to bend lines?•Have you avoided the I-beam effect? (See page 15 or Glossaryfor a definition of I-beam effect) •Are non-wiring holes at least 0.007" (0.18mm) (more pre-ferred) over the specified minimum distance from conductors and borders? P a d s a nd a nnu la r rin gs
•Are there pads on all layers for all plated through-holes?•Are non-exposed pads (via pads) 0.020" (0.51mm) larger thanthe through-holes (not applicable for micro vias)?•Are center locations provided for all drilled holes and/or slots? •Are the annular rings on all holes at .east 0.007" (0.18mm) larger than the specified minimum?•Are access holes in cover layers at least 0.007" (0.18mm) (more preferred) over the specified minimum distance from conductors and borders?•Are all pads filleted? 25
