Hi Guys
I found some people are using tscream and bcream layer, what are the usage of those layers? I seems to never submit a design with those two layers, is there anybody using them before and can explain the usage of them?
Thanks,
 

It is the solder paste later - a negative layer. It is used to create the solder paste stencil for manufacturing.

Dear Keith
Since I need to order stencil, do I need to include this layer in my design or not? If I do, how can I?
Thank you,
Brian

When I submit my design, I always does not include this layer. This time, I need to order stencil, do I need to include this layer?
thanks a lot
 

Yes, you need to add that to the CAM job when you create the Gerbers.

Do I need also include other layers? It looks like if I include all layers from 0 to 64, they will report some solder clearance problem.
Here is the link:

If I do need to include those two layers, how can I fix the problems?
Sorry for the endless questions.

How are you including the other layers? The layer numbers are 31 & 32 anyway - less than 64. If you add them to a CAM job, make sure that the file you create for the layer only includes the layers you want. For example, don't add layer 31 to layer 29 - they each need their own Gerber file to be generated.
