UF 120LA is a highly filled, high-purity liquid epoxy underfill designed by YINCAE to flow into narrow gaps. This advanced material is fully compatible with all no-clean solder paste flux residues, successfully passing 5×260°C reflow without any solder joint deformation. It outperforms competitor underfills, even those requiring a cleaning process, making it ideal for BGA, flip chip, wafer-level chip scale packages, and bare chip protection in various advanced packages like memory cards, chip carriers, hybrid circuits, and multi-chip modules.
