Unlike Framed stencils, frameless stencils are not permanently glued into a frame. They are designed to work within the “Universal Frame” system, also known as Reusable Frame Stencils. These stencils require less storage space and are economical for screen printing, for prototyping, or for small volume of PCB production. They are also less expensive than framed stencils, and save shipping costs.
For stencil without frame, pls tell us the size of it, or send us the outline file directly. Our engineer will follow your file.
SMT stencil is used to transfer solder paste to a bare printed circuit board. A stainless steel foil is laser cut creating an opening for every surface mount device on the board. Once the stencil is properly aligned on top of the PCB board, solder paste is applied over the openings (making a single pass, using a metal squeegee blade). When the stainless steel foil is separated from the board, solder paste will remain, ready for placement of the SMD. This process, as opposed to hand soldering methods, ensures consistency and saves time.
From Crown Key Electronics, you can order a stencil with any PCB together. Simply to write the size of the stencil you need, or let our engineer to suitable size according to your PCB design. There is some sizes and valid area of PCB stencil from Crown Key. See the below list for more details on the standard size stencils. If any special size or requirements, pls contact our sales by email.
