Cleaning of Circuit Board Assemblies
Abstract
When one thinks about printed circuit boards, also called PCBs or wiring boards, terms such as conducting tracks, computer chips, signal currents and of course soldering and solder joints may come to mind. Few know about the importance of cleaning in that regard. Some even fear that contact of circuits and with fluids is always dangerous, regardless of current flowing or not.
On the contrary, aqueous cleaning has a permanent place in electronics manufacturing in the field of stencil printing of solder pastes. Additionally, a fraction of soldered circuit boards of around 20% undergoes cleaning processes, especially for demanding applications such as automotive, where humidity and temperature cycling occur, or in aerospace and medical technology, where circuits have to be specifically fail-safe.
In this whitepaper we would like to familiarize the reader with the topic of circuit board and assembly cleaning.
