About This Product

Because it is designed not to interfere with the self-alignment behavior of solder, reflow soldering and adhesive curing can be carried out in a single step. It is also well suited to applications such as preventing large components from dropping during double-sided reflow soldering.

■Suppresses dropping, misalignment, and lifting of bottom-side components during double-sided reflow

When an ordinary adhesive is used together with solder paste, the adhesive cures before the solder paste melts, causing components to lift after reflow. JU-R4S does not fully cure while the solder is melting, encouraging the component to settle.

■Does not interfere with component self-alignment

JU-R4S is designed to begin curing after common lead-free solder (SAC305) has melted. It therefore does not interfere with the self-alignment of components that occurs when the solder melts.

■A stable dispensed application shape

With its viscosity lowered for better dispensing and its Ti value optimized for better shape retention, JU-R4S stably maintains a tall dispensed shape. It therefore makes reliable contact even with tall components and achieves good adhesion.
