Types of cleaning equipment
spray cleaning machine
system was applied to the direction of the force is perpendicular and debris attached to the space direction is level, and can effectively remove the exposure in the dirt on the surface, but for high density mounting device of dirt has little effect. Some spray cleaning machine is improved, increased by increase the number of nozzle and nozzle pressure, improve the temperature of the cleaning fluid, cleaning time, using patented "high power vertical spray pump" and "no shadow technology to make the cleaning liquid spraying by capillary action to penetrate into the bottom component, to effectively remove flux.
General spray cleaning machine use alkaline cleaning solution, compared to the cleaning liquid and neutral solvent cleaning fluid, easy to device of ink identity, anodic alumina and fixing glue caused wash, change the color and stripping effect, therefore, is to consider the process of replacement.
vapor phase cleaning
The washing part is arranged in the steam area, and the vapor state solvent is dissolved after condensation on the workpiece. With no mechanical force on the components of the damage is small, not completely immersed in the solvent is a semi dry cleaning. Vapor expensive and complex devices. And by solvent cleaning control: reduce the original cleaning agent due to environmental and steam equipment application, now the development of environmentally friendly cleaning agent such as bromine propane steam cleaning and gradually occupies a part of the market); II cleaning agent with high volatility and strong flavor, the operator adverse.
centrifugal cleaning machine
Immersion in the cleaning liquid in PCBA rotation, element of space and direction in the same plane, a large number of cleaning mixture and produced by the rotation of the centrifugal force and Coriolis force the cleaning liquid into the dirt containing space most closely. Due to the constant transformation of the direction of rotation, the liquid flows in all directions, these forces acting together in the flux and dirt, so that it quickly dissolved and washed. This cleaning method and spray cleaning actually use the cleaning fluid and the principle of mutual movement of the washed parts, the former is the PCB movement, the latter is the cleaning fluid movement. Compared to the latter, the former should consider PCB fixed, and it is too rough and rough, for the PCBA with precision components is not very applicable.
