... cases, the customer or design requires that soldermask be applied between surface mount lands. If the air gap falls below the minimum, then the | PRINTED CIRCUIT BOARDS SHOP | manufacturer will request a window void of the soldermask at that location. (Also take into consideration that there will be some etch compensation enlargement prior | PRINTED CIRCUIT BOARDS SHOP | to plot. This often times causes the CAM operator to shave the sides of the surface mount lands to ensure that there will be no | PRINTED CIRCUIT BOARDS SHOP | lifting and redepositing of soldermask flakes onto other features of the part.) Open Road: The standard rule should permit the windowing and voiding of soldermask | PRINTED CIRCUIT BOARDS SHOP | in the area. Otherwise, construct the land width small enough to permit a 0.007" air gap. SOLDERMASK CLEARANCE Bottleneck: Many Gerber files for soldermask come | PRINTED CIRCUIT BOARDS SHOP | with the clearance for the features as one-to-one. If the manufacturer left this artwork as is, the result will be end product with soldermask on | PRINTED CIRCUIT BOARDS SHOP | lands. This is not acceptable in most cases, though IPC standards permit encroachment ...
