The battery holder BC501SM-TR from MPD (Memory Protection Devices) can be put through the Water Soluble Flux Process.
Water-soluble flux is a kind of flux widely used in the electronic soldering process. It can improve the wettability of the solder, prevent oxidation and clean the residue with water after soldering.
The biggest feature of water-soluble flux is that the flux component is highly soluble and active in water with good fluxing performance, and the residue after soldering is easily soluble in water, so water can be directly used as the cleaning solvent. No consumption of ODS and VOC, reducing environmental pollution and safety risks.
Deionized water is recommended for eliminating water-soluble flux residue, as it is a safe and effective method. The method uses water-soluble flux in both leaded and lead-free pastes and solders, allowing them to be cleaned with deionized water. The in-line wash washes and rinses the PCB assemblies with deionized water jets at high temperatures and pressures. The water temperature is 144 degrees Fahrenheit, and the pressure is 45 pounds per square inch. After that, the assemblies are air dried using a series of driven air jets. To ensure cleanliness, resistivity, and ionics testing are utilized.
One should be aware that a wash can sometimes dissolve the plating and affect the soldering.
