产品描述
NanoSlic nano coating is a next-generation stencil coating technology developed to meet the growing demand of the electronic assembly industry and the refinement of electronic components. NanoSlic Nanocoatings are polymers that coat the bottom surface and pore walls of stencils. This durable coating is both highly hydrophobic and oleophobic, improving the release properties of the solder paste. NanoSlic heat cures and is a permanent coating. NanoSlic technology improves solder paste transfer efficiency for small apertures, resulting in higher yields and less rework. Cost savings and improved product yield; Plus, NanoSlic reduces bridging and underside cleaning. This coating technology can be easily evaluated and is compatible with current assembly equipment and processes. And it has been widely recognized and used by many customers at home and abroad.
NanoSlic Nanocoating
What is NanoSlic Nanocoating?
NanoSlic Nanocoating is a polymer template coating designed to minimize underside cleaning and improve transfer efficiency.
How does NanoSlic nanocoating work?
NanoSlic is applied to the pore walls and below the template and provides a hydrophobic and oleophobic surface. This prevents solder paste from sticking to the stencil to which the coating is applied. The benefits of this include reduced bridging, minimal undersurface cleaning and improved solder paste release. The volume of solder paste increases significantly when using NanoSlic nanocoating.
How does NanoSlic nanocoating differ from other coatings on the market?
NanoSlic nanocoating is a thermally cured polymer that is thicker than conventional nanocoatings. The most common nanocoatings are rubbed onto the stencil. NanoSlic coatings are a few microns thick. This is a very durable, chemically resistant coating.
Does NanoSlic nanocoating affect template thickness? Aperture size?
Aperture length and width decrease with coating thickness, but template thickness increases NanoSlic thickness. The net change in aperture volume is about 5% and depends slightly on aperture size. NanoSlic can increase the volume of printed paste due to its excellent paste transfer efficiency. This largely compensates for the slight drop in aperture size.
Will the NanoSlic nanocoating peel off?
The coating is designed to be a permanent part of the formwork. The stencil may be damaged and become unusable before the NanoSlic nanocoating shows any signs of wear.
Are NanoSlic nanocoatings compatible with cleaning chemicals?
Most cleaning chemicals are compatible with NanoSlic nanocoatings. However, higher pH (>11) cleaners can damage the coating over time. A list of recommended cleaning chemicals is listed in the technical data sheet.
What happens if the NanoSlic nanocoating comes off in the print paste?
This coating is non-ionic and chemically inert and becomes part of the flux residue around the solder joint. If a water-soluble solder paste is used, the coating is easily washed away by the flux. If clean solder paste is not used, the coating becomes an inert part of the flux residue.
Are NanoSlic nanocoatings toxic?
The coating is non-toxic and compliant with RoHS, RoHS2 and REACH regulations.
Is the NanoSlic nanocoating visible on the stencil?
Yes, the NanoSlic nanocoating is easy to see on the stencil so you know it's there and functional. The wipes on the coating are often invisible, so it's hard to tell when they stop working.
If the NanoSlic nanocoating is damaged, can it be reapplied?
NanoSlic nanocoatings cannot be re-coated onto previously coated stencils.
Can NanoSlic nanocoating be applied to used production templates?
yes and no. The stencil must be completely free of all solder paste residue, but we recommend applying a freshly cut and cleaned stencil to ensure proper bonding.
Does the application of NanoSlic nanocoating change the stencil delivery time?
Yes, NanoSlic coating adds one day lead time.
