Defluxing PCB Cleaning Systems for the Electronics Industry
PCB cleaning (or defluxing) plays a vital role in reliability. In addition, defluxing ensures the product works for its designed life expectancy.
This cleaning process is designed to remove solder flux and by products from the PCB assembly including oils, tape residues, finger prints, etc. In an environmentally-conscientious world, some manufacturers are keeping up with consumer demand and are producing environmentally-friendly defluxing systems such as Aqueous Technologies.
Safety of employees and the safe removal of these contaminates is something Aqueous prides itself on. Aqueous defluxing systems are designed to safely remove contaminates, posing no threat to the environment or humans. The Trident range by Aqueous Technologies provides a complete automatic de-flushing system from wash to rinse to cleanliness, monitoring, drying, and SPC without the need to install drains, acquire permits or treat and manage waste water. The Trident range provides fully automatic wash, rinse, cleanliness verification, and dry functions and can remove any flux from any alloy without sending a single form of fluid to the drain.
PCB cleaning chemistries are automatically dosed, mixed and reused. This can significantly increase the effective life of a cleaning chemistry and reduce consumable expenses. A powerful multi-impeller stainless steel pump precisely controls fluid to twenty rotating stainless steel spray nozzles. The nozzles are designed to reduce the fluid droplet size for improved under-component penetration. This all reduces operating costs to the end user.
Benefits of the Trident range of PCB cleaning defluxing systems as opposed to competitors are:
The solvents used by competitors are more commonly flammable. Not only are most solvents flammable, but their vapours may also be flammable. Be sure the machine is equipped with the appropriate Australian safety rating for flammable liquids and vapour. The solvents commonly used by competitors contain high levels of VOCs (Volatile Organic Compounds). Many of these high VOC-based solvents have been banned in Southern California and other urban areas.
Many of the solvents used by competitors are toxic to humans. One should present a strong need before choosing to clean with these solvents. Trident only uses non-flammable cleaning chemicals which have been rated “better than” solvent-based cleaning materials. Cleaning chemicals used in Trident are generally considered environmentally and operator safe. Trident is a batch-configured, aqueous-based, spray-in-air format cleaning/defluxing system. By far, this is the industry’s most popular cleaning format.
