StikNPeel™ FAQs

Q: How many times can a StikNPeel™ stencil be used to rework a location?
A: StikNPeel™ stencils are designed for single use.

Q: What thicknesses are available for the StikNPeel ™ stencil?
A: The StikNPeel ™ stencils are available for 4 (0.10mm), 5 (0.13mm) and 6mil (0.15mm) thicknesses.

Q: What files can Stencils Unlimited accept to design my customized StikNPeel ™ stencil?
A: 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.

Q: How small/large can the area of my StikNPeel ™ be?
A: The smallest area would be 2 x 2mm (75 mils) and the maximum area is 2.5"(63.5mm) x 2.5".

Q: What are the practical limits of this rework stenciling technique for leaded devices?
A: 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 ™.

Q: What are the practical limits of this rework stenciling technique for BGAs?
A: 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 ™.

Q: What is the shelf life of StikNPeel ™ preforms?
A: If stored in optimal conditions (see datasheet) the adhesive system of the StikNPeel ™ stencil has a shelf life of 2 years.

Q: What is the smallest aperture opening that can be made?
A: 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.
