One-Step Underfill 688 is a non-odorous, low surface tension, reworkable one component epoxy resin designed as a one-step underfill for flip chip, CSP, BGA and µBGA assemblies. Acts as a flux and an underfill. May be applied directly after the SMT printing process and cured during the standard Pb-free reflow process. Can be used in mixed alloy solutions, such as Pb-free BGA on a tin lead board. Is said to offer reliability through high Tg, low CTE, and good fill with no voiding. Is compatible with no-clean flux residues. May be reworked at 120°C. Viscosity reportedly remains stable throughout shelf life. Wets to OSP, ENIG, immersion silver and immersion tin board surfaces.

The VacuNest compliant tooling system for printing, dispensing and placement machines has a working area of up to 330 mm x 330 mm; the tabletop configuration is said to handle shape memory tooling beyond board handling. Each module is a pliable anti-static chamber containing a foam former surrounded by polymer granules. The chamber reportedly can be profiled within 30 sec. to the shape of the work piece assembly or enclosure. Under vacuum, the profile can be retained indefinitely; can be reconfigured for the next job after assembly batch is complete.
