The current market requirements regarding residual ion contamination levels for a cleaned assembly are typically <1 to 0.6 μg NaCl eq / cm2. Even smaller values can be achieved.
Find out which are the best options to reach these values in the best quality and most economically rinsing process and why an electrical zero conductivity of the rinse water is not necessarily the optimal solution!
A standard kolb system is designed for temperatures up to 55 °C because modern detergents have a efficiency window at a much lower temperature level. Nonetheless all systems are also available for high temperature cleaning up to 80 °C. Find out here why it is more efficcient, more process safe and more economic to use modern high performance low temperature cleaners.
According to experts, between 60 and 70 percent of all defects and failures during or after the soldering process are attributable to defects in the printing process - caused in in general by faulty solder joints, which in turn have their causes in solder paste printing mistakes. Find out here how stencil underside cleaning with the right cleaning medium avoids production losses and additional costs.
When it comes to cleaning of large volumes of PCBs, the question arises as to whether compact batch systems can handle similar capacities in similar times to large inline systems.
Learn here why the question should actually be the other way around.
