Step Stencils for Mixed Component Height and Paste Volume Needs
XFPCB supports step stencils when a PCB assembly needs different solder paste volumes for fine-pitch and large components on the same board.
XFPCB Step Stencil Service
XFPCB supports Step Stencil for SMT projects that need stable solder paste printing. We help confirm stencil thickness, aperture design, frame option and special areas for fine-pitch components or mixed paste-volume requirements.
For stencil work, provide paste Gerber, panel data, component density and any fine-pitch or large thermal-pad areas. XFPCB will help choose stencil thickness and aperture strategy for stable paste printing.
For Step Stencil, XFPCB combines engineering review, manufacturing preparation, quality inspection and export communication so your purchasing team can move from RFQ to delivery with a clear build plan.
Order Workflow
Stencil Design
Choose stencil thickness, frame and special aperture strategy.
Stencil Production
Manufacture the stencil for prototype or production use.
Future Revisions
Use assembly feedback to tune future stencil revisions.
How XFPCB Controls the Build
- Paste Gerber, aperture areas, fiducials and panel data are checked before stencil production.
- Stencil thickness is selected according to component pitch and paste volume requirements.
- Step, nano-coating or electroform options are applied when the assembly needs tighter paste control.
- Stencil files and production notes are kept for repeat assembly orders.

step-up and step-down areas
XFPCB reviews step-up and step-down areas against your submitted files, quantity and application requirements before confirming the build plan.
fine-pitch ICs
Clear fine-pitch ICs requirements help our team quote accurately, prepare production data and reduce avoidable clarification rounds.
large connectors
Our engineers confirm details for large connectors early, so your team can approve the order with clear next steps.
Useful Terms
- Aperture
- The stencil opening that controls paste deposit.
- Step-up
- A thicker stencil area for more paste.
- Step-down
- A thinner area for fine-pitch parts.
- Paste release

Step Stencil FAQs
What should I send to quote Step Stencil?
Send Gerber files, NC drill files, board outline, stackup notes, material, copper weight, surface finish, quantity and target lead time. For PCBA or assembly-related work, also send the BOM with manufacturer part numbers, pick-and-place data, assembly drawing, DNP notes and test expectations.
Can XFPCB review the files before production?
Yes. XFPCB can review manufacturability and quotation details before production starts. We check material choices, via structures, component package data, tolerance requirements and inspection requirements before release.
Can XFPCB support both prototype and production orders?
In most cases XFPCB can support both stages. Prototype builds help validate the design, while production planning controls repeatability, documentation, component supply and cost for future orders.
How can I reduce quotation delays?
Provide complete files, expected annual or batch quantity, destination country, special standards, inspection needs and the target schedule. If the design is still changing, tell us which details are fixed and which are under review.
Request a Quote for Step Stencil
Send your project information to XFPCB and our team will review the key manufacturing or assembly details. A complete RFQ helps us respond with a more accurate quote and a clearer production plan.
- For bare PCB projects, include Gerber, drill, stackup, material, copper, finish, quantity and lead time.
- For PCBA projects, include BOM, pick-and-place file, assembly drawing, test notes and approved alternatives.
- For application-specific projects, share operating environment, reliability expectations and packaging needs.
