NovaCentrix's Rudy Ghosh, PhD, to Explore Photonic Soldering during Online SMTA Chapter Meeting


Reading time ( words)

NovaCentrix, the industry’s leading provider of photonic curing tools, conductive inks and the new PulseForge® Soldering high-intensity pulsed-light solution, is pleased to announce that Rudy Ghosh, PhD, will present during an online joint SMTA chapter meeting on Thursday May 13, 2021 from 1-2 p.m. PST.

The presentation will explore photonic soldering, which uses high intensity flash lamps as an alternative to laser soldering. This is a combined chapter meeting with the following 8 SMTA Chapters: Boston, Capitol, Central Texas-Austin, Heartland, Los Angeles/Orange County, Oregon, Puget Sound, Silicon Valley (San Jose).

Ghosh will present, “Use of flash lamps to achieve non-equilibrium soldering and assembly using conventional solder alloys.” The drive to enhance human interactivity and reduce weight of electronic systems has led to the use of non-conventional substrates. As the substrates become thinner, more flexible and economical, the thermal stability of the working substrate is significantly lowered. As such, the conventional modes of component attachment are no longer functional.

To bridge this gap, anisotropic adhesives and tapes, as well as low temperature solders and conductive epoxies, have been developed. However, in terms of performance, conventional soldering is still the champion.  One way to combine traditional soldering techniques with thermally sensitive substrates is laser soldering. However, technical challenges, combined with the high costs of lasers, continue to create barriers to a broader adoption.

This discussion focuses on photonic soldering, which uses high intensity flash lamps to overcome the disadvantages of laser soldering; while still enabling soldering on a wide range of substrates. Similar to laser soldering, photonic soldering utilizes selective absorption of light to enable conventional solders to affix commercial packages on the underlying thermally unstable substrate.

As the Technical Program Lead at NovaCentrix, Ghosh helps translate technical innovations into customer ready products. He works closely with customers, technology partners, and collaborators to solve technical challenges and identify new avenues for the application of the technology for printed and flexible electronics. He works with the global business team to define and engage in commercial opportunities related to the technical program and furthers those areas of opportunity through industry outreach and engagement. 

Previously, Ghosh was a Post-Doc at the Microelectronics Research Center at the University of Texas at Austin, where he led the Center’s research into the synthesis of 2D materials. He holds a PhD in Physics from the University of North Carolina at Chapel Hill and a MS in Physics from the Indian Institute of Technology, Bombay. He has authored over 30 publications in a variety of technical journals.

I recently spoke with Rob Boguski, president of Fremont, California-based Datest and an SMTA vice president and board member. Rob explained why today’s test customers are asking for more information than the traditional pass/fail, offers a preview of SMTA International, and gives an update on SMTA’s planning strategy for the next five years.

Four Silver Linings in the Stormy Clouds of Pandemic, Supply Chain, and Inflation

09/14/2022 | Dr. Ronald C. Lasky, Indium Corp.
It may be difficult to see any bright spots in the current and recent economic situation. We have all experienced the devastation of the pandemic, supply chain issues, and most recently, inflation. However, as a senior technologist for an international materials supplier (Indium Corporation) and a professor of engineering at an Ivy League research university (Dartmouth College), I offer these four silver linings for those of us in the electronics industry.

Solder Paste Printing and Optimizations for Interconnecting Back Contact Cells

07/26/2022 | Narahari S Pujari and Krithika PM, MacDermid Alpha Electronics Solutions
The interdigitated back contact (IBC) is one of the methods to achieve rear contact solar cell interconnection. The contact and interconnection via rear side theoretically achieve higher efficiency by moving all the front contact grids to the rear side of the device. This results in all interconnection structures being located behind the cells, which brings two main advantages. First, there is no frontside shading of the cell by the interconnection ribbons, thus eliminating the need for trading off series resistance, losses for shading losses when using larger interconnection ribbons. Second, a more homogeneous looking frontside of the solar module enhances the aesthetics.
