Current IssueInner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.
Alternate Metallization Processes
Traditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop.

Indium's Dr. Jie Geng to Present at IPC Electronics Materials Forum
October 25, 2019 | Indium CorporationEstimated reading time: 1 minute
Indium Corporation expert Dr. Jie Geng, Research Metallurgist, will share his knowledge at the IPC Electronics Materials Forum, November 5-7, Minneapolis, Minn., USA.
Dr. Geng will present Fluxes Designed for Suppressing Non-Wet-Open during BGA Assembly, which examines the increasing severity of warpage and non-wet-open (NWO) defects during BGA assembly due to the continuing advancement of miniaturization. He will discuss how a “cold-welding barrier” method utilizing a flux coating has been developed to suppress NWO defects.
He will also present A Novel Medium-Low Temperature Solder Paste, detailing the development of a new lead-free solder paste with a reflow peak temperature of 200°C. The finished solder joint melted between 180–200°C, allowing for a hierarchy assembly process with alloys that have melting temperatures around 140°C, 190°C, and 220°C.
Dr. Geng focuses on the development of novel lead-free high-reliability solder alloys for automotive applications. He also investigates the assembly process technologies in electronic packaging and interconnections. Dr. Geng earned his Ph.D. in Metallurgy from University of Surrey in the U.K. He continued as a materials scientist after graduation and has extensive experience on materials selection, design, processing, and characterization, especially on processing-structure-property relationships in various materials, including ultra-high temperature alloys, lightweight alloys (Al and Mg), magnetic materials, and ceramics. Dr. Geng is skilled in combinatorial and high-throughput material design using 3D printing and computer programming with Python. He has published more than 20 journal articles in the field of materials science and engineering. He also serves as a peer reviewer for numerous journals.

Book Excerpt: The Printed Circuit Assembler’s Guide to... Low-Temperature Soldering, Vol. 2, Chapter 5
12/23/2024 | I-Connect007 Editorial TeamChapter 5 introduces the advantages of using low-temperature soldering for through-hole components, including cost efficiency, reliability improvement, and reduced warpage. Also covered: the evaluation of different fluxes and the performance of HRL3 in wave soldering and selective soldering processes.
Overview of Soldering Systems With Vacuum
12/18/2024 | Dr. Paul Wild, Rehm Thermal Systems GmbHWhen soldering electronic assemblies, the focus of the vacuum application is on the removal of volatile substances from the solder joints and the associated reduction of pore formation. Particularly in the thermal management of power electronics components, pores can cause so-called hotspots with higher temperatures due to their poor heat conduction. These hotspots can lead to overheating of the components on the one hand and to thermally induced destruction of the solder structure on the other.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
12/13/2024 | Andy Shaughnessy, I-Connect007This week, Peter Tranitz discusses the upcoming Pan-European Electronics Design Conference, set for Jan. 29-30 in Vienna, Austria. Pete Starkey brings us a review of the most recent EIPC Technical Snapshot webinar, which featured a global PCB maker update by Dr. Hayao Nakahara. Don't miss our interview with Manfred Huschka, who explains how companies can begin their own China Plus One plan. Stan Farnsworth breaks down photonic soldering and discusses its use in soldering materials that are not typically compatible. I also enjoyed Dan Beaulieu’s discussion on the value of consistency, and why just showing up for work is half the battle, especially in an inconsistent, evolving industry like ours.
Advancing Photonic Soldering
12/11/2024 | Nolan Johnson, SMT007 MagazineStan Farnsworth, director of customer satisfaction at PulseForge, discusses the advancements in photonic soldering that highlight its energy efficiency and versatility. Over the past two years, the company has refined its applications for flexible substrates and energy reduction, finding that photonic soldering allows the processing of materials that typically aren’t thermally compatible and offers significant energy savings compared to traditional methods.
