Henkel CSP and BGA Underfills Description:
Henkel offers innovative capillary flow underfill encapsulants for flip-chip, CSP and BGA devices. These are highly flowable, high purity, onecomponent encapsulants. They form a uniform and void-free underfill layer to improve reliability performance by redistributing stress away from the solder interconnects as well as enhancing mechanical performance. We have formulations that quickly fill very small gap/pitch parts, offer fast cure capabilities, have a long pot and shelf life, and are reworkable. Reworkability allows for cost savings by allowing the removal of the underfill to enable re-use of a board.
Flip-chip applications require assistance with redistributing stress away from the solder joints to extend thermal aging and cycle life. A CSP or BGA application requires an underfill to improve the mechanical integrity of the assembly during a bend, vibration or drop test. Henkel’s flip-chip underfills are formulated with a high loading of specialty fillers to achieve low CTEs yet maintain the ability to flow fast in small gaps, possessing high glass transition temperatures and high modulus. Our CSP underfills are designed with little to no filler loading, a choice of glass transition temperatures, and modulus to match the intended application.
For certain applications, Loctite Cornerbond and Edgebond technologies allow for cost-effective underfill solutions. The Cornerbond technology is applied at all four corners of the package and then can be cured during the normal solder reflow cycle, allowing for a more efficient process. The material’s self-centering characteristic ensures high assembly reliability and outstanding yield rates.
