Product Description EC-200 is for the SMT printing stencil cleaning residues development of a neutral water-based environmentally friendly cleaning agent, can effectively remove solder reflow SMT stencil printing solder paste residues before and uncured red plastic residues , especially for off-line spray cleaning process. The product uses our patented technology developed, with high washing load capacity and excellent filtration resistance, long life, low odor, no foam. As electronic products small, lightweight, precision-oriented development, electronic cleaning in the manufacturing sector becomes more and more important, relative to conventional cleaning agents, EC-200 neutral aqueous cleaners eliminate the fire safety problems, better meet the ever-increasing level of environmental protection material requirements, conform to the future direction of the cleaning industry. Applications EC-200 neutral water-based cleaning agent is particularly suitable for off-spray cleaning process can also be applied to the ultrasonic cleaning process to remove residual SMT solder paste screen printing plates and red plastic residue. For various types of flux residues also have some solubility. Specific application results are listed below list. Applications: stencils and misprints edition clean solder paste (before reflow) SMT solder paste printing stencils ★★★ (before reflow) ★★★ wrong printed circuit board uncured red plastic SMT stencil printing ★★ water-soluble PCBA ★ rosin-based flux residue flux residue PCBA ★ low solids flux residues PCBA O ★ ★★: Strongly recommended, the best results; ★★: Recommended; ★: possible; O: not recommended. Advantages? Two-phase water-based cleaning agent with a high load capacity and excellent cleaning filterability, therefore a longer service life, lower maintenance costs. ? Using deionized water as solvent, no flash, safe, no additional explosion protection. ? Gentle formula, PH neutral, sensitive metal, mesh panels, stretching rubber, plastics and other polymers have excellent material compatibility. ? Does not contain VOC components to meet regulatory requirements related to VOC emissions. ? Odor, less impact on the environment. No foam, no foam to meet the requirements of high-pressure spray. ? Free of solid matter, without rinsing after cleaning, no solid residue, no blush.
