Dry ice cleaning demonstrates excellent performance and wide application in the removal of PCBA flux.
1. The Effectiveness of Dry Ice Cleaning for PCBA Flux
In the electronics manufacturing industry, the cleanliness of PCBA (Printed Circuit Board Assembly) is crucial for the performance and reliability of products. Flux, as an auxiliary material in the soldering process, effectively promotes soldering; however, the residue left on the circuit board after soldering can affect circuit performance and even lead to issues such as short circuits and corrosion. Therefore, selecting an efficient and safe cleaning method is particularly important.
As an emerging cleaning technology, dry ice cleaning showcases outstanding results in the removal of PCBA flux due to its unique advantages. Dry ice cleaning utilizes dry ice particles (solid carbon dioxide) that, when rapidly sprayed, create physical impacts and heat exchange with the surface being cleaned, causing the flux to freeze, become brittle, and fall off. Additionally, the heat absorbed during the sublimation of dry ice further accelerates the cleaning process. This cleaning method effectively removes flux residue.
