PV Nano Cell Successfully Prints Inside VIA for High-Demanding Application
February 6, 2020 | PV Nano CellEstimated reading time: 2 minutes
PV Nano Cell, Ltd. (OTC: PVNNF) ("PV Nano Cell" or the "Company"), an innovative provider of inkjet-based conductive digital printing solutions and producer of conductive digital inks, today announced that it has successfully printed and tested high-demanding parts that include printing inside challenging VIA—vertical interconnect access.
VIA are used as an electrical connection between layers (or sides of substrate) in a physical electronic circuit that goes through the plane of one or more adjacent layers. PV Nano Cell was able to print inside VIA with a diameter of 0.6 mm (0.024 inch) and a height of 1 mm (0.04 inch). A phenomenal, minimal resistance of 0.1 ohms was measured and the company said it could print smaller sized VIA as well. One side of the substrate is printed a pattern consisting of multiple widths and thicknesses (heights) of conductive features. This pattern forms an accurate resistor that heats to high temperature in less than milliseconds.
PV Nano Cell’s Chief Executive Officer, Dr. Fernando de la Vega, commented, “In this special application, we first print inside the VIA. Then we print the first designated pattern on one side of the FR-4 (glass-reinforced epoxy laminate material). The substrate is then flipped over and we print the second designated pattern on the other side of the FR-4. The VIA printed in the beginning of the process electrically connects between the two patterns printed on the two sides of the FR-4 substrate. The unique printing process that we developed cuts approximately 50% of the cost of production compared to the existing manufacturing solution. We are positive we can improve the process even more and print smaller-sized VIA.”
PV Nano Cell is implementing these technologies and products to provide a complete solution approach that allows customers to fully realize the potential of inkjet based electronics printing for mass production applications. The company’s proven solution includes its proprietary Sicrys™, silver-based conductive inks, inkjet production printers and the complete printing process.
PV Nano Cell’s Chief of Business Development Officer, Mr. Hanan Markovich commented, "The printed parts have gone through intensive, high-demanding standard testing by the customer and we expect the production to begin in the near future. Such an achievement demonstrates again, the feasibility and attractiveness of PV Nano Cell’s solutions for mass production applications.“

Trouble in Your Tank: Materials for PWB Fabrication—Drillability and Metallization
07/16/2024 | Michael Carano -- Column: Trouble in Your TankLaminate materials are the building blocks on which printed circuit boards are manufactured. Circuit board designers rely on the critical electrical properties of the materials to design the interconnects, and with the drive toward IoT (internet of things), autonomous driving, and virtual and augmented reality, material properties take on a very high level of importance.
Don’t Overconstrain Your Board Materials
07/02/2024 | I-Connect007 Editorial TeamWhen we started planning May’s issue, which centers on the use of traditional laminates in certain high-frequency PCBs, we knew we had to interview Kris Moyer and Ed Kelley together. Kris teaches advanced PCB design classes for IPC, and Ed is the former CTO of Isola and founder of Four Peaks Innovation. What ensued was a wide-ranging discussion on the evolution of “standard” PCB laminates and the recent trend by some OEMs to use these materials in high-frequency and even RF boards.
Underconstraining Your Materials? Leave It to the Experts
05/30/2024 | I-Connect007 Editorial TeamWith traditional laminates now sporting improved resin systems, some OEMs are choosing various flavors of FR-4 instead of high-speed laminates for their high-speed designs—even RF applications. Avoiding overconstraining your materials in high-speed products can lead to considerable cost savings, not to mention a more streamlined trip through fabrication.
The Shaughnessy Report: Unlock Your High-speed Material Constraints
05/15/2024 | Andy Shaughnessy -- Column: The Shaughnessy ReportThe world of PCB materials used to be a fairly simple one. It was divided into two groups: the “traditional” laminates, often called FR-4, and the high-speed laminates developed especially for high-speed PCBs. These were two worlds that usually didn’t collide. But then traditional laminates started getting better, and high-speed designers and design engineers took notice and started to reconsider what FR-4 could be used for.
Breaking High-speed Material Constraints: Design007 Magazine — May 2024
05/14/2024 | I-Connect007 Editorial TeamDo you need specialty materials for your high-speed designs? Maybe not. Improvements in resins mean designers of high-speed boards can sometimes use traditional laminate systems instead of high-speed materials, saving time and money while streamlining the fab process. In the May 2024 issue of Design007 Magazine, our contributors explain how to avoid overconstraining your materials when working with high-speed boards.
