This service provides quick and high quality laser cut stencils. There are two kinds of stencils,one of the stencil without frame;the other of the stencil with frame. If your design meet the requirement, the stencil will be fabricated in 24 hours and shipped in 2-3 days.

Gerber file requirement (The following layers are needed):
| Top Paste layer: | pcbname.GTP |
| Bottom Paste layer: | pcbname.GBP |
| Top Silk Layer: | pcbname.GTO |
| Bottom Silk Layer: | pcbname.GBO |
Note:
- Stencil material: SUS304H-TA/AB glue/Aluminium-frame.
- No limitation on panelizing.
- The Gerber file must be RS-274x format.
- If there are GBP layer and GTP layer(Bottom Paste layer and Top Paste layer), please also provide the Bottom silk screen layer. so that the stencil engineer will know whether mirror the bottom layer or not.
- We will open all the paste layer, but there are also some exception sometimes, such as standard golden fingers, standard RF antenna.
- If there is no paste layer, but there are Solder Mask layer, Top Layer and Bottom layer. we will manufacture it according to Solder Mask layer and the size of the pads
- The regular thickness of the stencil will be 0.1mm,0.12mm,0.15mm,0.18mm or 0.2mm, if you need other thickness stencil, please contact us via email: pcb@elecrow.com or order@elecrow.com
- The shape of holes on the stencil for the SMT pads may a little difference from the gerber file. especially for the big pads
