Enhance your surface mount technology process with our custom-made stencils
At UnityPCB, we know that accuracy is critical in the assembly of printed circuit boards. Solder paste deposition on PCBs needs to be as precise as possible, which is why our SMT stencils are designed to deliver great performance. Quality, reliability, and our many years of expertise make us your ideal contact for outstanding SMT stencils.
This kind of stencil is fixed in the frame, it has higher rigidity and stability. They are ideal for high-volume production runs and for products that require high accuracy.
Frameless SMT stencils are typically reusable, therefore they have lower costs than those with frames. Also, they allow for easy storage and transportation, ideal for prototypes and short-term production.
Prototype SMT stencils are fast to manufacture, and their prices are cheaper. They are most effective during the initial phase of the product development, because they allow to easy testing and adjustments.
Nano-coated stencils have a special nanocoating over the surface to provide easier release of solder paste and low defects, which yield high precision and reliability of PCBA.
This type of PCB stencil is made with electroforming process. It has very low aperture tolerance and smooth wall surface, well-suited for tasks that require high pin density.
These stencils have accurate aperture and come with a clean edge due to laser cutting technologies. They’re featured with uniform deposit of solder paste and ideal for different applications.

Our engineers work with you closely throughout the process, from designing to post-delivery, they provide expert guidance.
An SMT stencil is essentially a thin foil which is produced from materials such as stainless steel, nickel, etc which is used to apply solder paste correctly to a printed circuit board. It makes sure that solder paste is deposited on the PCB pads to where components will be installed.
SMT stencils are typically manufactured using one of three methods: by using laser cutting, chemical etching or even electroforming. Laser cutting is the most common due to its precision and ability to create fine apertures.
Using the appropriate solvents and cleaning methods to clean surface mount stencil, on the other hand, proper handling and storage are also important.
Yes, SMT stencils can be used repeatedly as long as they are well cleaned up and stored in the right manner after use.
Yes, UnityPCB offers custom SMT stencil designs tailored to meet the specific requirements of your PCB assembly process.
