Core Capabilities & Specifications
Stencil Types & Precision
Stencil Varieties: Laser cut stainless steel (standard), electroformed (ultra-fine), step (mixed thickness), flexible polyimide (prototypes)
Aperture Tolerance: ±0.025 mm (25 microns) – ensures consistent solder paste volume for fine pitch components (01005, BGA, QFN)
Thickness Range: 0.1mm to 0.25mm –Adapt to different solder paste quantity requirements (fine pitch 0.1mm, large components 0.25mm)
Maximum Panel Size: Up to 600mm x 600mm – supports large PCB panels for mass production
Lead Time & Surface Finish
Lead Time: Prototype orders (3–5 business days); mass production (7–10 business days)
Surface Finish: Electropolished (minimizes solder paste sticking)、chemically treated (enhances paste release) – reduces printing defects

FAQ
Q1: What is the advantage of laser cut PCB stencils over other types?
A1: Laser cut stencils offer higher aperture precision (±25 microns) and sharper edge definition than etched stencils, making them ideal for fine pitch components (01005, BGA, QFN) – they reduce solder bridges and insufficient paste defects by 40% on average.
Q2: What stencil thickness options do you offer?
A2: We provide thicknesses from 0.1mm (for fine pitch 01005/0201 components, ensuring minimal solder paste) to 0.25mm (for large passive components or through-hole-in-pad designs, delivering sufficient paste volume).
Q3: Can you produce step stencils or partial panel stencils?
A3: Yes, we specialize in custom step stencils (e.g., 0.1mm for resistors + 0.2mm for BGA on one stencil) to solve mixed component height issues. Partial panel stencils are also available to reduce material waste for small-batch PCBs.
Q4: What is the typical lead time for laser cut stencil orders?
A4: Prototype stencils (for R&D or small tests) are ready in 3–5 business days, including Gerber file review and aperture optimization. Mass production orders (10+ stencils) take 7–10 business days with batch inspection.
Q5: Do you provide framed and frameless stencils?
A5: Yes, both options are available. Rigid framed stencils (aluminum frames) work with automated SMT printers for mass production, while frameless stencils are cost-effective for manual printing or lab-scale assembly – both are compatible with most industry-standard equipment.
Applications & Customer Considerations
Key Applications: Laser cut stencils are essential for high-precision solder paste printing, especially for advanced components like 01005 passives, QFN (quad flat no-lead), BGA (ball grid array), and fine pitch ICs (≤0.4mm pitch) – they directly determine assembly yield and reliability.
Thickness Selection: Choose 0.1–0.12mm for fine pitch components (avoids solder bridges) and 0.15–0.25mm for large components (ensures sufficient solder joint strength) – our engineering team provides free thickness recommendations based on your BOM.
Finish Impact: Electropolished finishes are recommended for fine apertures (≤0.2mm) to prevent paste sticking, while chemically treated finishes are better for high-volume production (enhances paste release speed).
Design Optimization: We offer free Gerber file review to adjust aperture size/shape (e.g., teardrop apertures for BGA) – this reduces printing defects by 30% and improves first-pass yield.
