... most cases, the customer or design requires that soldermask be applied between surface mount lands. If the air gap falls below the minimum, then | CIRCUIT BOARD | the manufacturer will request a window void of the soldermask at that location. (Also take into consideration that there will be some etch compensation enlargement | CIRCUIT BOARD | prior to plot. This often times causes the CAM operator to shave the sides of the surface mount lands to ensure that there will be | CIRCUIT BOARD | no lifting and redepositing of soldermask flakes onto other features of the part.) Open Road: The standard rule should permit the windowing and voiding of | CIRCUIT BOARD | soldermask 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 | CIRCUIT BOARD | come 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 | CIRCUIT BOARD | on lands. This is not acceptable in most cases, though IPC standards permit ...

... are usually preferred by fabricators because they're easier to work with and have smaller file sizes than positive layers. Remember, boards are manufactured en | CIRCUIT BOARD | masse and must be stepped out into a panelized form. The result: Data sets with lots of unnecessary positive planes swell exponentially, bog down CAM | CIRCUIT BOARD | systems, and crash photoplotters. After the basic prep work is completed, step into the fabrication analysis arena, where the game is one of checks and | CIRCUIT BOARD | balances. You've got your design rules; fabricators have theirs. Checks and balances can resolve any conflicts between the two. Take soldermask layers, for instance. Often, | CIRCUIT BOARD | these layers are not "intelligent" layers within a CAD tool; that is, there is not much in the way of capability checking within the tool. | CIRCUIT BOARD | As a result, these are among the more troublesome layers for fabricators. The solution here is a fabrication analysis tool that can handle such issues | CIRCUIT BOARD | as clearances, coverage, webbing, and so forth. For instance, most ...
