Hybrid and Printed Circuit De-fluxing

Interlab offers both highly sophisticated, and very simple, equipment configurations for flux removal. The fully automated INTRAX line of semi-aqueous, non-ultrasonically-agitated de-fluxing systems is shown above. Where fluxes are purely aqueous and water rinsable, our ultra-pure DI rinse/recirculation systems and HEPA-filtered dryer units may be an ideal alternative.

The INTRAX was developed for the very demanding needs of the hybrid industry, using organic de-fluxing chemistries to eliminate the most activated fluxes from even fine-pitch geometries. Effective agitation using proprietary non-ultrasonic means ensures damage-free cleaning. Ultrasonic agitation is also available as an option.

2-stage high-purity DI rinsing using our recirculation technology reduces water consumption while ensuring parts purity, which can then be confirmed using the built-in resistivity monitor. Interlab’s patented contamination-free HEPA-filtered dryer then quickly eliminates water droplets and even entrained moisture. The INTRAX is available in 2 sizes, one for full-sized PC boards, and one for hybrid circuit manufacture.

For water-rinsable fluxes, our Soniscan® 14-2 Rinser/Dryer features a high-purity DI delivery, recirculation, and regeneration system built into the overflow rinse bath. This unit also includes resistivity monitoring, capillary drying, and an MD-250 non-contaminating evaporative dryer, all in a single compact console.

Interlab also manufactures a DI recirculating sink and flammable-solvent-compatible systems, including IPA vapor degreasers, which can be used for circuit cleaning.
