ZESTRON, the global leading provider of high precision cleaning products, services, and training solutions in the electronics manufacturing and semiconductor industries, is pleased to announce that Jigar Patel, M.S.Ch.E., Senior Application Engineer, will present “Solder Mask and Low Standoff Component Cleaning—A Connection?” at IPC APEX Expo 2020 in San Diego, CA.
Introduction: Today, printed circuit boards used within electronic assemblies for high reliability applications are typically subjected to cleaning or defluxing processes. As assembly complexity has increased, that is, more densely populated with greater use of stacked and leadless components and with ever reducing standoff heights, effective defluxing is increasingly challenged.
The author’s purpose in conducting this study was to assess the under-component cleanliness as impacted by different solder mask options which are used to protect the copper traces and pads integral to PCB design. The solder mask specifications used in this study included: Solder Mask Defined (SMD) and Non-Solder Mask Defined (NSMD). No Solder Mask (NoSM) was also tested for comparative purposes.
Jigar Patel will present the Design of Experiment and key results during the Cleaning track on Thursday, February 6th, from 9:00 AM to 10:00 AM. For more information, please visit www.ipcapexexpo.org.

We were back in San Diego, maybe for a “long vacation,” as IPC APEX EXPO is in Anaheim next year. Before we get to Anaheim, though, let’s talk about the show: It was a great week. I spent Sunday and Monday visiting some excellent Professional Development courses. As you know, this is a fast-changing industry, and we have to keep learning to stay ahead. On Monday, I attended the Microvia Weak Interface/Reliability subcommittee, and on Tuesday, the Ultra-HDI Technology Committee.

Alpha Circuit is a PCB fabricator located in Elmhurst, Illinois. Given that the launch of a new PCB fab is a rare occasion these days, we caught up with the senior team—Prashant Patel, president and CEO; Steve Smith, general manager; Steve Ryan, sales and direct support—guiding the buildout of Alpha Circuit’s brand new 44,000 square foot facility. They discuss what goes into equipment selection and line design, and the timing couldn’t have been better. At press time, the new facility was on schedule for test production by the end of January 2023.

If you’ve ever experienced an electric car launching from a dead stop, felt the torque and acceleration that a motor made of magnets and copper coils can deliver over a combustion engine, then you’ll have a sense for how this year’s SMTAI took off—both literally and figuratively.
