Heming Technology -IPC "cleaning guide" Standard Unit President, R & D production and sales of electronic manufacturing cleaning agents, water-based cleaning equipment, national high-tech enterprise flux, solder paste. ??? 20 years to concentrate on business, electronic manufacturing experience, we explore different areas in a recent application. Cleaning the SMT process, PCBA cleaning, steel mesh, copper mesh and plastic mesh cleaning, SMT equipment maintenance, reflow, wave soldering and maintenance, and many other applications to power electronics and assembly cleaning. I. Introduction??? W1200 is a neutral water-based cleaning agent, specially developed for cleaning aluminum tray or fixture to be baked on flux and other residues. Mainly suitable for ultrasonic cleaning process, soaking and manual cleaning methods. The product uses our patented technology developed by excellent material compatibility, can be used for a variety of cleaning sensitive metal materials. Low odor, halogen-free, no flash. As electronic products small, lightweight, precision-oriented development, electronic cleaning in manufacturing becomes increasingly important, as opposed to traditional cleaners, W1200 water-based cleaning agent, the complete elimination of fire safety problems, to better meet the constantly enhance environmental substances rating requirements, comply with the future direction of the cleaning industry. Second, the advantages: 1, a variety of aluminum and other metal materials have sensitive security compatibility, to solve the alkaline water-based cleaning agent has been unable to overcome the problem. 2, using deionized water as a solvent, no flash, safe, no additional proof measures. 3, does not contain VOC components to meet regulatory requirements related VOC emissions. 4, light scent, PH value neutral, safe operation, no additional protective measures, the operator easy to accept. 5, because it is a concentrate, according to the residue can be cleaned after the degree of difficulty, the use of different proportions diluted cleaning. 6, heating the cleaning liquid (40-50 ℃) or by using ultrasonic cleaning, the cleaning time can be greatly shortened. Third, the application? W1200 can be used in the ultrasonic cleaning process, manual cleaning methods and soak cleaning process for cleaning aluminum tray or fixture to be baked on flux, for all types of flux and solder paste residues have good solubility, apply effects listed below list. Applications: cleaning and maintenance of water-soluble solder paste flux residues residual ★★★ ★★★ ★★★ rosin-based flux residues low solids flux residues ★★★ ★ smoked synthetic flux contamination ★★★ ★★★: Strongly recommended, the best results; ★★: Recommended; ★: possible; O: not recommended. Fourth, a cleaning process, ultrasonic cleaning??? In the ultrasonic cleaning process, the aluminum fixture will be immersed in the cleaning tank, the use of ultrasonic cavitation in the cleaning agent, acceleration effects and the role of a straight flow, and cleaning agents super solubility of dirt combine to make the dirt layer is dissolved, dispersed, emulsified, or peel to achieve the purpose of cleaning. 2, soaking manual cleaning and manual cleaning mode refers to the way of the cleaning liquid sprayed on the surface of the workpiece, or the workpiece into the cleaning solution after soaking, and then manually wiping or brushing. For cleaning and maintenance, manual cleaning equipment is more commonly used as a cleaning method, the process is very simple operation, cleaning equipment requirements are relatively low.
