SMTA Capital Chapter Hosts Webinar on Next-gen pH Neutral Cleaning Products
November 6, 2020 | SMTAEstimated reading time: 1 minute
The SMTA Capital Chapter is excited to host another free webinar on Friday, November 13. The webinar will include an informative presentation given by industry expert Ravi Parthasarathy of ZESTRON Corporation on “Accelerating Continuous Improvement with Next Generation pH Neutral Cleaning Products.”
Electronic assemblies continue to grow more complex in terms of component design, board density, standoff heights, and increased use of sensitive material sets. Different market sectors may have unique materials sets that need to be considered when developing and/or selecting a chemistry for the cleaning process. These advances continually challenge the cleaning process. Often times, cleaning process improvement can be realized by increasing the cleaner mechanical energy through spray bar design, pressure and configuration, thermal energy by increasing the cleaning agent wash temperature, and chemical energy by increasing the cleaning agent concentration. However, chemical energy can also be increased through increased solvency of the cleaning agent itself.
The presentation will discuss the technical study done by Ravi Parthasarathy, M.S.Ch.E., Senior Application Engineer, ZESTRON Corporation and Terry Price, Ph.D, R&D Scientist, ZESTRON Corporation. In this study, two EMS companies explored alternate cleaning agent options in pursuit of continuous process improvement and meeting new product cleaning challenges. Each company was using an inline cleaner with a water-based cleaning agent and each had an optimized process that met their cleaning process requirements. However, they elected to explore the benefit of a cleaning agent with greater solvency to improve overall process efficiency and cleaning performance.
This presentation reviews their current cleaning process as well as presents field data detailing the cleaning process performance improvements and resulting cleanliness levels achieved on complex electrical assemblies using a cleaning agent with greater solvency. Examples of the new challenges will be discussed, and the resulting field data detailed.

Elementary, Mr. Watson: Ensuring Design Integrity
03/28/2024 | John Watson -- Column: Elementary, Mr. WatsonBack in February, many of us watched the "Big Game." It reminded me of the saying, “It's not how you start that is important, but rather how you finish." It is perfectly okay when you are talking about sports, you get off to a bad first half and need to recover in the second half. However, when it comes to PCB design, this is not a good practice. If things start badly, they usually don't recover. They continue down that same path, costing more money and losing design time.

IPC APEX EXPO 2024: LPKF—Debunking Depaneling Industry Perceptions
03/27/2024 | Nolan Johnson, I-Connect007In this audio interview, listen to Jake Benz discuss advances in laser depaneling at LPKF. Thanks to advances in laser technology, perceptions about laser depaneling are changing from a low-speed, specialized process to a high volume process suitable for production manufacturing. Benz elaborates on some of the development and engineering that went into creating their latest, most capable depaneling machines.
The Many Complexities of PFAS
03/26/2024 | Marcy LaRont, PCB007 MagazineIn its simplest definition, PFAS is a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. Fluoropolymer coatings can be in a variety of products. Though this definition is not inaccurate, it can be misleading. Depending on who you ask, there are upward of 10,000 PFAS chemistries that can meet various definitions.
