Austin, TX – June 13, 2024 – NovaCentrix, a global leader in printed electronics materials such as conductive inks, has collaborated with PulseForge, a pioneer in advanced thermal processing solutions, to present groundbreaking advancements in flexible hybrid electronics (FHE). This collaborative effort was highlighted at the International Conference on Electronics Packaging (ICEP) held in Toyama, Japan from April 17-20, 2024.
In their joint presentation, NovaCentrix and PulseForge unveiled new findings that address critical performance gaps in FHE manufacturing, particularly in interconnection and component attachment. The study focuses on the innovative use of PulseForge photonic curing and soldering to enhance the structural quality and performance of FHE devices, which are integral to the next generation of low-temperature and low-cost flexible substrates.
Advancements in Photonic Curing and Soldering
The research showcased at ICEP 2024 detailed the use of photonic curing and photonic soldering processes to create a flexible hybrid circuit. The circuit components were attached to ink traces printed with Metalon® HPS-FG32 using commercially available solder paste and built on low-temperature polyethylene terephthalate (PET) film. This approach yielded circuits with superior electrical performance, avoiding thermal damage typically associated with traditional methods.
Key highlights of the study include:
Enhanced Electrical Conductivity: Photonic curing with the PulseForge model IX4-52-45 system produced higher electrical conductivity in printed circuits compared to those cured in a convection oven.
Superior Mechanical Strength: The photonic soldering process resulted in solder junctions with higher mechanical strength. The photonic-cured traces exhibited an average shear force of 1.36 kg, compared to 0.64 kg for oven-cured samples.
Structural Integrity: Scanning electron microscope (SEM) and energy-dispersive x-ray spectroscopy (EDS) analyses revealed distinctive boundaries and improved structural integrity in photonic-cured traces, highlighting the formation of stronger metallurgic structures.
Impact and Future Applications:
The collaboration between NovaCentrix and PulseForge demonstrates the significant potential of photonic curing and soldering in advancing the field of flexible hybrid electronics. The results indicate a promising pathway for overcoming current limitations in FHE manufacturing, offering improved electrical performance, mechanical strength, and structural integrity.
“This collaboration exemplifies our commitment to innovation in the field of printed electronics,” said Charles Munson, CEO of NovaCentrix. “The advancements achieved through our partnership with PulseForge open new possibilities for the development of new materials and processes that push forward the ecosystem of high-performance printed and flexible electronics that are both economical and environmentally friendly.”
“We are thrilled to collaborate with NovaCentrix and showcase our advanced photonic curing and soldering capabilities,” added Jonathan Gibson, CEO of PulseForge. “The results presented at ICEP 2024 highlight the transformative potential of our technology in enhancing the performance and quality of printed electronics. This partnership underscores our dedication to pushing the boundaries of what’s possible in electronic manufacturing.”
