A PCB stencil is a thin metal sheet used to apply solder paste onto a printed circuit board during surface mount assembly. The stencil contains cutouts at the precise locations where solder paste is required to mount SMT components onto the board.. This article provides a comprehensive overview of PCB stencils covering their design, manufacturing process, materials, critical parameters, usage ...
WhatsApp: +86 18203695377For 3D shapes like the yoyo project below, a 1/8" or 1/16" ball end mill produces the smoothest contours. For best results, keep a set of end mills specifically for Delrin and other plastics, and never use them to cut metal or PCBs. This allows for increased milling speeds and a better finish.
