Who Needs Precision Cleaning? Development and selection of solvents for precision cleaning

摘要

Precision cleaning to stringent standards to ensure the final product provides reliable and trouble-free performance. A vast array of industries - including the aerospace, transportation, telecommunications and data processing industries - all employ critical electronics and circuit boards whose failure can be catastrophic. The printed circuit boards (PCBs) employed in these systems must be cleaned with a solvent prior to their use to remove flux and other soils introduced during the PCB manufacturing process. Products used in the semiconductor industry require precision cleaning to meet stringent performance criteria. The aerospace industry requires precision cleaning of landing gear to eliminate fracturing of landing gear parts due to trapped water. The jewelry and watchmaking industries demand an end product that is aesthetically pleasing, spot-free and void of any soils. Medical devices ranging from surgical needles to artificial heart valves must be cleaned to stringent standards to prevent infection and the spread of disease. The automotive industry requires precision cleaning of critical parts such as fuel injectors, ABS brakes, compressors, relays, sensors and switches. Solvents are also required for the spot-free cleaning of optical parts including optical assemblies, lenses, fiber optics and flat-panel displays.
