Photo Stencil Debuts Novel Nano Layer Stencil Coating at IPC APEX

Published on February 19, 2013 at 4:55 AM

Photo Stencil, LLC, a leading full-service provider of high-performance stencils and tooling, introduces its new Smart-Release™ nano layer stencil coating at IPC APEX Booth #1215. Tests performed at OnCore Manufacturing Services, LLC, Longmont, Colorado, showed that Smart-Release considerably reduced the frequency required for under-screen cleaning on the printer, saving time, money and consumables, reducing defects and contamination, and improving throughput. The test results demonstrated that over 40 prints before cleaning can be reached, with no deterioration in print quality or bridging.

“We compared the results of PCBs with and without Photo Stencil’s Smart-Release nano coating and we found measureable advantages,” said John Ross, manufacturing engineering manager, OnCore Manufacturing Services. “Smart-Release reduces the spread of solder paste under the stencil even when the stencil is not making good contact to the PCB pad. The resulting process is faster and more efficient, while achieving excellent printing results.”

“The direct cost of cleaning a stencil is about $0.15 for each cleaning, so each additional print that can be made before the stencil needs to be cleaned saves $0.15,” explained Rachel Short, VP sales and marketing, Photo Stencil. “As demonstrated in our collaborative tests with OnCore, using Smart-Release coated stencils can result in 40 additional prints before cleaning is necessary. And that cost savings doesn’t include the time and labor involved in cleaning or the loss of throughput.”

During screen printing, solder paste adheres to the underside of the stencil, gradually causing a build-up of paste which can potentially contaminate the board and prevent the stencil gasket from sealing tightly. With Photo Stencil’s new Smart-Release nano layer stencil coating, the solder paste separates more easily from the stencil, with less contamination on the underside. Apertures and component edges are cleaner for more exact printing results. Smart-Release is available on all types of stencils, including laser cut, electroformed, NicAlloy, and chemetch.

Photo Stencil will be exhibiting at IPC APEX, San Diego, CA, from February 19-21, 2013, at booth #1215. Photo Stencil experts will be available to discuss your printing challenges.
