Product Introduction
UF 88UL is a super-fast flow capillary underfill designed by YINCAE, capable of flowing into a 10μ gap at room temperature without substrate preheating. This advanced material ensures void-free underfill after cure and allows for easy rework. UF 88UL is versatile, suitable for underfilling chip scale packages, ball grid array devices, package on package, land grid array, and certain flip-chip applications. It also provides bare chip protection in various advanced packages like memory cards, chip carriers, hybrid circuits, and multi-chip modules. Engineered for high-production environments where process speed and mechanical shock resistance are critical, UF 88UL is easily dispensed, minimizes induced stresses, and delivers outstanding reliability, including superior temperature cycling performance and excellent mechanical resistance. Its performance in drop tests shows a two-order-of-magnitude improvement compared to solder paste applications.
