Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

Austin American Technology (AAT) is pleased to announce that it has entered into a collaborative relationship with Specialty Coating Systems (SCS). SCS Ionic Contamination Test Systems set the standard of quality for the industry. Designed for fast and accurate ionic contamination cleanliness testing, the systems provide a precise, repeatable and rapid method for determining cleanliness and deliver immediate process control results, eliminating the need for outside laboratory testing.

This report hopes to achieve several goals: 1. Determine the link between bare PWB contamination, soldered assembly contamination and long-term product reliability. 2. Establish measurable limits for bare PWB cleanliness as well as process control limits for both an aqueous as well as a water-soluble soldering process. 3. Determine whether there is any correlation between common, industry-accepted rose/modified rose (omegameter/ionograph type) testing and long term product reliability. 4. Determine the effect PWB plating finish (HASL, Immersion Silver and Cu OSP) has on both bare PWB contamination as well as soldered assembly in a no clean and water soluble process. 5. Determine whether there is a link between percentage of saponifier used to wash soldered assemblies and long-term reliability. 6. Establish a more cost-effective test for manufacturers to use as a process-monitoring tool.
