Stencil Specifications

Our Stellar Stencil are made in Germany.

Frame

We add a frame around the actual PCB dimensions so that it is easy to place the PCB beneath it. The frame has the following dimensions around the PCB:

  • Left and right: 20 mm (0.79 in)
  • Top: ≥ 48.5 mm (1.91 in)
  • Bottom: 46.5 mm (1.83 in)

PCBs with a width less than 40 mm (1.57 in) get a slightly wider frame on the left and right side:

  • Left and right: 28 mm (1.10 in)

Pad Shrinking

As we will take care of shrinking the SMD pads, the actual drawing should have no pad shrinking. Otherwise it’ll double. We shrink the pads by 15% in volume.

Material

We only use high quality Japanese-made polished stainless steel for our stencils. They come with a thickness of 100μm.

I got Stellar Stencil for the first time today. I don’t know how that works. The Stellar Stencil has holes and so does the frame of the board, but the two don’t match. If the holes match, the SMD don’t match. How does this work ?

Hi @Thomas_Pienkny-TP-Co ,

Welcome to the community!

I assume that you selected the Rapid Registration Add-On when you placed your order?

You will need a compatible registration device to align the modified pcb and stencil.

Please find more information in this article here.

Hello,
I want to order a stencil for a project and I cannot import a good file…

Can you please tell me what kind of file is needed?

Also, I have top and bottom paste: is it possible to have both in one stencil?

Thanks in advance
