Atlanta, Georgia – Koh Young Technology, the industry leader in True 3D measurement-based inspection solutions and the premier sponsor of SMTA International, is proud to announce Daniel Perry, Regional Sales Manager for Koh Young America, will present a whitepaper about conformal coating inspection on Tuesday, October 22, 2024 at 10:30am CDT in the technical conference at the Donald E. Stephens Convention Center. The paper will provide an update on the journey towards zero defects and how electronics manufacturers can optimize the dispensing process with true 3D inspection of conformal coating and other dispensed materials. Additionally, Koh Young will be displaying its inspection solutions in the exposition on October 20-24, 2024.
Electronics manufacturers increasingly rely on conformal coatings to enhance the reliability of their products in challenging environments. These coatings play a crucial role in protecting electronics from moisture, debris, corrosion, and mechanical stress, thereby reducing failure rates. However, ensuring the effectiveness of these coatings is challenging due to the limitations of current inspection methods. The constraints of manual or 2D inspections prevent accurate measurement of critical aspects such as material thickness and coverage, especially for transparent materials. Consequently, today’s conformal coating inspection processes lack the reliability of true 3D inspection techniques.
Traditional laser-confocal and electron microscopes, although capable of measuring three-dimensional shapes, fail to inspect transparent materials due to their shallow penetration depth. Optical systems that use UV light are limited to simple 2D presence detection. Daniel will discuss L.I.F.T. technology (Laser Interferometry for Fluid Tomography) as a solution for non-destructive 3D inspection, enabling precise measurement of wet and dry fluids, including material thickness, at production speeds. This technology utilizes low-coherence interferometry and Near-Infrared Light (NIR) to capture images through multiple layers of a fluidic structure, regardless of transparency.
“The move towards zero defects is not just an aspiration but an achievable goal with the right tools and techniques,” said Daniel Perry. “At Koh Young, we are committed to providing innovative inspection solutions that empower electronics manufacturers to optimize their processes and ensure the highest levels of quality and reliability.”
The presentation will consist of four sessions. It will start by examining the overall market situation, focusing on major applications in the SMT industry, and highlighting several conformal coating inspection challenges. Following this, an update on potential solutions to overcome these challenges will be introduced. Finally, the presentation will explore updated methods to achieve a zero-defect process, surpassing current limitations.
