Trouble in Your Tank: The Role of Organic Solderability Preservatives in Advanced Packaging
The SCHMID Group, a global leader in high-tech solutions for the electronics industry, proudly announces significant updates to its flagship InfinityLine H+ Electroless Cu system. Specifically designed for the production of high- performance advanced packaging applications using mSAP and SAP processes, the system reflects SCHMID’s expertise in horizontal electroless copper deposition. With more than 40 years of experience in horizontal electroless Cu processes for high-end PCB and SLP applications, SCHMID combines this legacy with extensive know-how from the advanced packaging industry.
The InfinityLine H+ overcomes the disadvantages of widely used vertical batch processes by introducing newly developed horizontal inline process modules, add-on processes, and an optimized transport system. This latest advancement underscores SCHMID’s dedication to delivering cutting-edge solutions tailored to the evolving needs of manufacturers.
The upgraded InfinityLine H+ achieves highly uniform Cu deposition and features innovative enhancements, including an ozone module for pristine surface preparation, an advanced electroless copper module design, and a revolutionary three-point transport system that eliminates contact with active areas. These innovations empower manufacturers to achieve unprecedented yields in metallization processes while unlocking new technological capabilities.
Each panel is automatically treated under identical process conditions using highly efficient flood boxes that precisely target treatment areas—a significant advantage over traditional vertical basket systems. The horizontal process enhances the uniformity of copper thickness and provides superior performance in rinsing and drying substrate panels. Combined with the state-of-the-art SCHMID Watch 3.0 HMI and process control system, which leverages the decentralized H+ bus system for active and passive components, the InfinityLine H+ offers a smarter and more sustainable production solution.
"The new InfinityLine H+ Electroless Cu exemplifies our steadfast commitment to innovation," said Laurent Nicolet, Vice President of Business Units Electronics. "Compared to vertical batch applications, we achieve more uniform Cu deposition with high adhesion, even on low- roughness ABF materials. By reinventing key system components, the horizontal processing advantages are now accessible to the substrate industry. Together with our proven H+ modular platform, this system offers a more advanced, smarter, and sustainable solution for advanced substrate production, perfectly aligning with current and future manufacturing needs."
