In response to your detailed description of a specially formulated high-concentration aqueous cleaning fluid such as SJ-01, here are a few key points and measures to ensure that this cleaning fluid does not cause damage to delicate electronic components during the cleaning process:1. Excellent wetting propertiesSoftening and wetting flux: SJ-01 has excellent wetting properties, which can effectively soften and wet sticky flux residues. This means that it can easily penetrate and break down these residues without applying too much physical pressure, reducing the risk of mechanical stress on sensitive electronic components.2. Low surface tensionPenetrate into narrow gaps: The cleaning fluid has a low surface tension, which allows it to easily penetrate into very narrow gaps between the chip and the substrate. This not only helps to thoroughly remove flux residues in hard-to-reach areas, but also avoids component damage that may be caused by using high pressure or strong brushing.3. Excellent dissolving powerGentle but effective cleaning: Despite its highly concentrated formula, SJ-01 is designed to be a gentle and efficient solvent that effectively dissolves flux without affecting the surface of the material. This means that it can be safely applied to semiconductor devices in a variety of packaging forms without corroding or attacking metal parts or other sensitive materials on the circuit board.4. Rinse without residueCompletely remove residue: In addition to its powerful cleaning ability, SJ-01 also has excellent rinsing properties, ensuring that all flux residues are completely rinsed away without leaving any traces. This is crucial for subsequent process steps (such as underfill) as it guarantees perfect zero-void wetting and prevents quality problems caused by residues.5. Suitable for automated cleaning equipmentSpray/ultrasonic compatibility: SJ-01 is suitable for spray and ultrasonic cleaning equipment, both of which provide gentle and uniform cleaning force without direct contact or friction with the surface of electronic components. By selecting the appropriate cleaning parameters (such as temperature, time, flow rate, etc.), the cleaning process can be further optimized to minimize the impact on components.6. Rigorous testing and certificationMaterial compatibility testing: During the development phase, these professional cleaning fluids are often extensively tested for material compatibility to verify their suitability for use with specific types of electronic components. Manufacturers also follow strict industry standards and specifications to ensure that their products meet or exceed relevant requirements.7. Environmental friendliness and safetyReduced chemical hazards: As an aqueous cleaning fluid, SJ-01 is more environmentally friendly and health-friendly than traditional organic solvents. Lower volatility and toxicity mean less risk to operators during use, while also reducing potential threats to the environment from accidental leaks or improper handling.Through carefully designed formulas, scientific and reasonable application methods, and strict quality control, special aqueous cleaning fluids like SJ-01 can effectively remove flux residues while ensuring that no damage is caused to delicate electronic components. Whether for daily production or special application scenarios, it provides a reliable and efficient solution.
