SMT StencilSMT Stencil or Surface Mount Technology Stencil is a fine laser-cut stainless-steel sheet, ideal for using in PCB assembly. The PCB stencil helps in transferring the solder paste with precision and accuracy. The types of stencils that we can provide you are:

Internal size is the size compatible with that of PCB ready to be assembled while overall size refers to the size compatible with printer parameter limit. As long as both sizes are accurately designed, stencil will be able to make full use of its functions. Internal size of stencil can be figured out conforming to the following rule:
Width of Framed Stencil = width of PCB + 100mm while its Length = length of PCB + 100mm For example, if one circuit board size is 50*50mm, then the size of its framed stencil should be around 150*150mm and the size of its frameless stencil should be around 250*250 mm. It's easy to remember and operate so it worked for manual solder paste printing in SMT assembly prior to the advent of automatic printer. It can be said that different PCB sizes lead to generations of different internal sizes of stencil. When it comes to automatic solder paste printer, however, it's relatively solid. Overall size of stencil has to be determined by parameter limit of the equipment, that is, printer, because stencil has to work within the range of printer with a frame. Different printers feature different parameter regulations. As far as POE is concerned, the stencil size compatible with our printer can be either 650mm*650mm or 736mm*736mm. |
