KYZEN announced today that KYZEN’s Director of Science, Adam Klett, PhD will present as a keynote speaker at the SMTA Electronics in Harsh Environments Conference. The event is scheduled to take place May 14-16, 2024 at the Technical University of Denmark in Copenhagen, Denmark.
Klett will present “The Effect of Cleanliness on the Linearity of the Current Response of Standard SIR Patterns at High Voltages,” at 1:30 PM on Thursday, May 16, serving as the keynote address of the third and final day of the conference.
The keynote presentation is summarized as the following: Surface insulation resistance (SIR) is a well-established technique for the detection of ionic contamination of PWB coupons that applies a 5V bias to an interdigitated comb pattern and measures the current response in order to calculate the surface resistance of the sample. Certain applications, e.g., automotive, have high-voltage circuits that require SIR testing, but the question has been posed, “Does the current standard of 5V apply in these applications?”
In “The Effect of Cleanliness on the Linearity of the Current Response of Standard SIR Patterns at High Voltages,” the linearity of the current response of both clean and contaminated SIR coupons are characterized at high voltages in order to understand the relationship between contamination and test voltage and the measured SIR response. This will help steer the development of better test methods and acceptance criteria for SIR in high-voltage applications.
The SMTA Electronics in Harsh Environments Conference, hosted by SMTA Europe, addresses the wide variety challenges and best practices for design and manufacturing of electronics devices to preform reliably when used in harsh environments. The 2024 conference features three full days of technical programming including a keynote presentation each day.
