Stop Mask,: If there are silkscreen objects drawn in layers 21, 25, 27 for components on the Top layer, and 22, 26, and 28 for components on the Bottom layer overlapping the area of a solder ,stop, symbol generated in layer 29 and 30,
Masks,. The ,Masks, tab defines the dimensions of solder ,stop, and cream ,masks,. They are given in percent of the smaller dimension of smds, pads and vias and can have an absolute minimum and maximum value. Solder ,stop masks, are generated for smds, pads and those vias that have a drill diameter that exceeds the given Limit parameter.
4/5/2011, · here is an example where to use the solder ,stop mask,. The voltage regulator is mounted horizontally on the PCB and you don't want the solder ,stop, underneath the IC for better cooling. Using the solder ,stop mask, in that area the PCB manufacturer will leave a …
Layer 35-36: tGlue/bGlue. These two layers include both the top and bottom side of your glue ,mask,. This ,mask, is useful for securing components to your board that you expect to encounter stress during daily use, such as switches, jacks, or connectors.
You can ignore ,Stop Mask errors,. This indicates a section where silkscreen overlaps exposed portions of the board. This is automatically corrected during fabrication, and does not need to be corrected on the design. Generating Manufacturing Files. We accept ,Eagle, .brd files directly, so generally you will not need to generate the manufacturing ...
28/3/2010, · After you've updated the library, try adding another of the parts that had the drill size/,stop, size ,errors,. ,Eagle, will see there are differences, and ask if it's OK to update the part in the schematic. Let it update the part in the schematic, but don't actually add the part. Then go back to your ERC and DRC to see if the ,errors, have cleared up.
10/4/2014, · When you draw a surface mount pad in a custom ,Eagle, library package, it has a solder paste stencil aperture (aka "cream" layer) and a solder ,mask, aperture (aka ",stop," layer) automatically generated with it. I think these can dynamically change when the component is …
EAGLE, generates by default a solder ,stop mask, for each Via (also for Pads and SMDs, of course). This means the Via is free of coating material. The solder ,stop mask, is drawn automatically in the layers 29, tStop , for the top side and 30, bStop , for the bottom side.
with a zillion ,stop mask errors, - essentially everywhere there was a ,stop mask,. Turn off visibility and no more ,errors,. Why does making the ,stop mask, layer visible affect whether or not there is an ,error,? I am using ,Eagle, 6.0 on a Windows 7 computer. Robert Scott Ypsilanti, Michigan
always generate solder ,stop mask, By default a via with a drill diameter that is less than or equal to the value of the Design Rules parameter ",Masks,/Limit" will not have a solder ,stop mask,. The above ,STOP, flag can be used to force a solder ,stop mask, for a via.
