Enhancing BGA Package Performance with Proven and Innovative Ball-Attach Fluxes

The ball-attach process for BGA packages starts with applying flux, often via pin-transfer from a dipping tray. Next, solder spheres (solder balls) are placed into the flux deposits, followed by reflow of the entire assembly. A reliable ball-attach flux is essential to ensure both the success of this process and the long-term reliability of the final package. Indium Corporation offers high-performance, standard water-soluble ball-attach flux and leads the industry with the first ultra-low residue, no-clean ball-attach flux, onto the flux deposits, specially designed for delicate devices.

Advanced Ball-Attach Flux Solutions for Optimal Performance

Strong Wetting

Ball-attach flux solutions ensure optimal wetting on all metal surfaces, even those with significant contamination or oxidation.

易于清洁

Water-wash flux residue can be effortlessly cleaned post-reflow using pure DI water at room temperature, eliminating the need for chemicals or heated water.

一致性

Consistent flux volume, whether through pin transfer or printing application, is maintained over an extended period of time.

No-Clean

Ultra-low residue ball-attach flux is the perfect choice for sensitive devices that are increasingly difficult to clean sensitive devices.
