Details :

• The primary function of a PCB stencil is to deposit a precise amount of solder paste onto specific locations on the PCB, known as solder pads
• Stencils are essential for SMT (Surface Mount Technology) processes, where components are mounted directly onto the PCB surface. 
• Stencils are aligned with the PCB using fiducials (alignment marks) to ensure accurate paste placement
• Proper solder paste deposition is crucial for forming strong and reliable solder joints between components and the PCB.
