Stencil is used to mask the PCB when applying the solder paste before reflow soldering.
The stencil can be cut correctly if the Gerber files contain the solder mask layer. The extension of the required Gerber files are .GTP and .GBP.
In absence of the layer the stencil is prepared with automatic methods. In this case we do not take responsibility for the inaccuracy of the stencils.
The stencil thickness is 0.15 mm. The thickness may be thinner if our colleagues think it is better for the application.
Stencils can come with or without framework:
- With framework
- Without framework
The compact stencil is a 200 mm x 190 mm big piece, that comes without framework.

The four options are
- The Top+Bottom (on single stencil) option will place the pattern of the bottom layer and the top layer next to each other, on one stencil. ATTENTION: The valid area has to be twice the size in this case.
- The Top option will place the pattern of the top layer of the board on one stencil.
- The Bottom option will place the pattern of the bottom layer of the board on one stencil.
- The Top+Bottom (on separate stencils) will place the pattern of the bottom layer and the top layer.
Electropolishing, also called BGA plating, is highly recommended for boards with BGAs or ICs with pin to pin spacing that is less thanequal to 0.5mm. The process will help the paste detach from the fine stencil apertures.
Fiducial marks are alignment marks for surface mount assembly machines. Generally, these are a must for machine operation. Not necessary if the parts are places by hand.
Order process
- Upload your Gerber files in zip format to begin the order process.
- The uploaded project is automatically analyzed by the system and sets the basic parameters of the PCB in order to make a quote.
- To finalize the quote, change the parameters of the stencil. For additional information click (?) signs.
- The expected price, production time and product weight are automatically updated after each parameter change.
- Adding the order to the basket is possible using the "ADD TO CART" button.

Additional information on the stencil
- For accurate cutting of the stencil it is important to have the Gerber files with extensions .GTP and .GBP . in abscense of these files, the stencil will be cut using an automatic process that could result in inaccuracies. We do not take responsibility for these inaccuracies.
- The thickness of the prepared stencil is 0.15 mm. It will be thinner if our colleagues think it is more appropriate for the application.
