Present the Stencils Unlimited staff with the mechanical datasheet of the part, GERBER drawing including the paste layer section of the site you would like to rework or a dxf or dwg file and after order entry we'll let you review the stencil design prior to fabrication.
StikNPeel ™ stencils can be manufactured and have been tested for use for leaded devices down to 0.50mm pitch, 0.25mm aperture with 0.25mm spacing between apertures. Below these guidelines we suggest using a metal rework stencil or StencilQuik ™.
StikNPeel ™ stencils can be manufactured and have been tested for use for leaded devices down to 0.50mm pitch, 0.36mm aperture with 0.14mm spacing between apertures. Below these guidelines we suggest using a metal rework stencil or StencilQuik ™.
There is no practcial limit on the aperture opening but the webbing limit (ie the distance between 2 successive openings) is limited to 0.4mm (15mils). While smaller webbing distance can be machined using a squeegee to roll the paste in to the aperture openings becomes the limit.
