Frameless PCB stencils are designed to work with stencil tensioning systems and are optimum for short runs, prototyping and hand printing on Printed Circuit Boards (PCBs). The PCB stencil’s smooth aperture walls work well for ultra fine pitches, micro BGAs, and small bottom-terminated components. Frameless PCB stencils mount directly into a frame system without the need for glue or mesh.
