Leveraging our high-quality SMT stencil to make your surface mount PCB assembly work easier and more convenient.
What Is SMT Stencil
SMT Stencils, also known as PCB stencils, have always played an important role in surface-mount technology (SMT) assembly. They are used to deposit solder paste onto the substrate to form the necessary electrical connection between the component and the substrate. In recent years, the use of stencils has evolved beyond the traditional function of depositing solder paste. As the pitch of component leads has decreased, the use of stencils for applying adhesive has become increasingly common.
Benefits of SMT Stencil
SMT stencils can be used for almost all PCB manufacturing processes, which are not limited to any specific fabrication technique.
It ensures that the position of the solder paste pads is highly accurate and the aperture is consistent.
With SMT stencils, the paste can be applied to the entire PCB in one go, reducing the assembly time significantly.
Using laser-cut stencils, you can apply a smooth layer of solder past, so there are no gaps in the soldering process.
Types of STM Stencils Available at MOKO
Framed SMT Stencil
This kind of SMT stencil is fixed in the frame permanently, with the aid of a mesh border, the stencil foil can be stretched tightly which is conducive to high-accuracy printing. Compared to a frameless SMT stencils, it is more convenient as there is no need to stretch the stencil by yourself, and it is more suitable for high-volume production runs.
Frameless SMT Stencil
Frameless stencils or foils are 100% laser-cut sheets. you can use them in reusable frames. Comparatively, it offers a cost-effective and environmentally friendly solution. As a result, it is best for short runs and prototype PCB assembly. Furthermore, you can use it for both hand and machine soldering.
Prototype SMT Stencils
These stencils are made from CAD files or Gerber files and designed for hand-solder paste printing. Using prototype SMT stencils, can eliminate printing mistakes, and save you from soldering components on the circuit board to speed up the PCB assembly process.
Electroformed SMT Stencils
If you require the stencil for the most precise applications, Electroformed SMT stencils are the best solution for you. They are stencils made with electroformed foils, the raw material is nickel. The initial costs of this kind of stencil are high though, and it requires longer processing time than other stencils.
