PCB stencil manufacturer is a key search term for anyone involved in SMT assembly today. In 2025, with shrinking pitch sizes and increasing demand for tighter tolerances, choosing the right stencil partner is more critical than ever. Whether you’re a high-volume EMS company or a small-scale startup, selecting the right SMT stencil manufacturer makes a big difference in your production efficiency. Let’s explore key aspects of stencil design and production and uncover the top global and Indian manufacturers worth trusting.
Best Technology is a professional SMT stencil manufacturer. We have our SMT factories in China and Vietnam respectively. We provide SMT stencil, PCB fabrication, and turn-key PCB assembly service. In Best Technology, there are standard stencils, step stencils, and nano-coated stencils. Two critical considerations for stencil fabrication are dimensions and thickness. If you have any needs for PCB stencil, just provide us with GTP/GBP, GTO/GBO, Gerber file format (RS-247-x), and Fiducial Mark Data via sales@bestpcbs.com. It’s our pleasure to cooperate with you.
What is the material of the PCB stencil?
Most stencils are made from stainless steel. It’s the go-to material because of its strength, reusability, and precision. It can handle fine-pitch components and supports repeated solder paste printing without wearing out. For ultra-precise applications, nickel stencils offer smoother apertures and better paste release.
On the other end, polyester (Mylar) stencils are budget-friendly and ideal for quick prototyping. They’re easy to cut manually or with plotters but don’t last long.
Some stencil makers also offer nano-coated stainless steel, which improves solder paste release and reduces bridging—especially helpful for ultra-fine-pitch or micro BGA designs.
What is the thickness of the PCB stencil?
Stencil thickness plays a big role in paste volume. The standard thickness range is between 0.10 mm to 0.20 mm, depending on the type of components and their pitch.
0.10 mm (4 mil): Best for 0.3 mm BGA or 01005 chips.
0.12 mm (5 mil): Suitable for 0.4 mm BGA and mixed SMT components.
0.15 mm (6 mil): Used for 0.5–0.65 mm pitch ICs.
0.18–0.20 mm (7–8 mil): Ideal for large components with bigger pads.
If you go too thick, you risk bridging and excess paste. Too thin, and you may face cold solder joints. Always match the thickness with your smallest pitch. In Best Technology, the common thickness of PCB stencils are 0.06mm，0.08mm，0.1mm，0.12mm，0.15mm，0.2mm. Just feel free to let us know what is the thickness of the PCB stencil you need.
How much does a PCB stencil cost?
PCB stencil cost depends on size, material, frame type, and cutting method. Basic framed stainless steel stencils usually range from $30 to $100. Frameless stencils are cheaper. In Best Technology, For 370*470mm framed, etched stencil, the cost is only $39; laser cutting one need $69. Custom features like step-up/step-down or nano-coating may increase the cost, but they also boost performance and reliability. There is a short lead time for Standard Stencil, whose production cycle needs 1 day. But for the nano-coated stencil, it will require 3 days to produce.
How do you make a PCB stencil?
Making a stencil involves a series of technical steps that ensure accurate paste deposition.
1. Design Generation: The Gerber file’s paste layer is used to define the stencil layout.
2. Material Selection: Choose based on project need—stainless steel for production, polyester for quick prototyping.
3. Laser Cutting: A high-precision laser cuts apertures into the sheet.
4. Surface Treatment: The stencil undergoes electropolishing or nano-coating to smooth aperture walls.
5. Framing: Optionally mounted on a metal frame or kept frameless for universal holders.
Each step affects paste volume and application accuracy. That’s why professional suppliers never skip proper surface treatment and post-cutting checks.
