The most extensive use of DuPont™ Vertrel® specialty fluids in the electronics industry is in the cleaning of printed circuit boards (PCBs). Cleaning PCBs has recently become more challenging, mainly because:
- Lead-free solder is used and the temperatures for soldering have increased, leaving behind a more stubborn residue to be cleaned.
- More is being packed onto one PCB, drastically reducing the gap between the parts that are mounted on the PCBs and making it more difficult to clean.
DuPont™ Vertrel® has risen to the demands of the electronics world and is the solvent of choice for electronics used in critical operations. Its low surface tension allows DuPont™ Vertrel® to get through the tightest clearances, and its good solubility ensures a suitably cleaned product. Typical use for cleaning electronics (PCBs) is in a vapor degreaser.
In addition to the vapor degreasing cleaning application described here, there are several aerosol manufacturers that have developed aerosols for cleaning electronics using DuPont™ Vertrel®. Please contact us if you have any questions about developing aerosols using DuPont™ Vertrel® specialty fluids.
