PCB Washing

Printed circuit boards (PCBs) are the heart and brain of the electronic devices we use every day -- from consumer electronics and the vehicles we drive, to medical devices and much more. They're composed of non-conductive material and are etched with conductive tracks and pads, with additional components connected through soldering.

Electronics assembly or circuit board washing is important to consider for reliable and dependable products, even the tiniest speck of dust can have a fatal impact on the electrical properties of the integrated circuit. During the processing or production of electronic assemblies, contamination often remains on the PCB (printed circuit board). Those residues can cause a short circuit or be a problem for the reliability of the device. If a coating has to protect the PCB against external influences, you must first clean the assembly to ensure good adhesion of the coating.

Spraying deionized water through nozzles is a safe and effective solution for removing water-soluble flux residue. The in-line washing system uses deionized water jets at elevated temperature and pressure to wash and rinse the PCB assemblies. The water temperature is 144 degrees F, and the pressure is 45 psi. The assemblies are then air dried with a series of forced air jets.
