SMT Stencil
What is SMT Stencil
An SMT stencil, also known as a PCB stencil, is a tool used in surface mount technology, primarily for the precise printing of solder paste on a PCB. It is usually a thin plate made of stainless steel or other materials with a precise pattern of openings that correspond to pads on the PCB.
Benefits of SMT Stencil
Highly Accurate
stencils are able to print solder paste very precisely into the specified position, which is crucial for the tiny and high density solder joints of modern electronic assemblies.
Repeatability
In mass production, stencils ensure consistency and repeatability from one print run to the next, which is important for maintaining product quality.
High Productivity
Solder paste printing can be accomplished quickly and efficiently with SMT stencils, greatly increasing productivity compared to manual printing.
Reduced Defect Rates
Due to the consistency and accuracy of the printing, the use of stencils significantly reduces soldering defects such as short circuits and bridging.
