IPC-7525 does a good job of giving guidelines for designing stencils, including stepped stencils

Nowadays is not a big deal to cut step stencils. Stencil houses charge you around 100USD per step in addition to your regular price. Some places are welding the step area with a very small clearance and I have to say mostly it is pretty accurate. In

The main feature of the step on the stencil is the excess of paste on adjacent components. Clearance between step and fine pitch components must be at least 10 mm. Might better try over printing?

We will be exploring the exciting world of step stencils for the first time and I am looking for any advice from anyone using regularly. This direction is because we have large caps and soldered standoffs along with medium pitch LGA's and QFP's on sa

For components with the large pads, you can also use secondary soldering dispensing. Some printers like DEK have an option to mount a syringe with an auger valve to do dispensing after the printing step process. Obviously will not work if you have to

Looking for better design information than is contained in IPC 7525A. Specifically the minimum trough width and length of the step to achieve the necessary paste reduction.

I have that article. While some of the information is helpful, there is no direction as to the length and width of the step to achieve blade deflection to reduce paste.

Leave it to the Eurolanders to come-up with a goofy, confusing name for something simple. Stepped stencils are chemical etched or laser cut. IPC-7525 provides guidelines on designing stepped stencils. Look here http://www.ipc.org/TOC/IPC-7525.pdf
