The functionality of electronic devices continues to increase at an extraordinary rate. Simultaneously consumers are expecting even more and in ever smaller packages. One enabler for shrinking electronics has been the flexible circuit board that allows the circuit board to fit a wide variety of shapes. Flexible printed circuits (FPC) have the capability to be very thin and can have unpackaged components directly attached using surface mount technology (SMT) and flip chip on flex technologies. Bare die can also be thinned and attached very close to the circuit board. However one caveat of high density flexible circuit boards with thin die is that they can be very fragile. The use of back side films and underfill can protect the die making circuits more robust. For underfill to work well it requires good adhesion to the circuit board which can mean that flux residues under the die normally must be removed prior to underfilling.
World's First Solder Joint Encapsulant Perfect solution for customers looking to eliminate underfilling processes. The SMT 256 Individual Solder Joint Encapsulation Adhesive is the world’s first combined flux gel/individual solder joint encapsulati

Zymet has introduced a new reworkable underfill encapsulant, CN-1736, designed to underfill 0.4-mm pitch Package-on-Package (POP) assemblies. It has low viscosity and a lower CTE than its predecessors. Plus it has greater flux compatibility, making it suitable for use with a broader range of solderpastes and tacky fluxes.

Zymet Inc. has introduced a reworkable edgebond adhesive, UA-2605, that improves thermal cycle performance of CBGAs and plastic BGAs. In one trial, UA-2605 tripled the 0°C to +100°C performance of a CBGA, to nearly 2500 cycles. Previously, an underfill was needed to achieve this level of performance.

EAST HANOVER, NJ – Zymet has introduced a new silica-filled reworkable board-level underfill encapsulant, X2825, whose coefficient of thermal expansion, CTE, is 26 ppm/°C. The underfill enhances drop and shock test reliability and, compared to higher CTE underfills, provides superior thermal cycle performance.
