Modern PCBs with low standoff heights are not easy to clean. Flux residue is no longer just around the components but often completely filling the spaces under tightly spaced components.

Although a rinse cycle is critical in both spray-in-air batch and inline systems for high-reliability applications, it relies on DI-water only. Can a water-only rinse cycle deliver enough cleaning power for today’s tightly populated printed circuit boards?

ZESTRON engineers tested the effectiveness of rinsing at standoff heights of 1 mil, 2 mils, 3 mils, and 5 mils, using various rinsing protocols to see what DI-water could actually achieve.
