1、Product Overview
This water-soluble dewaxing fluid is specially used for cleaning wax, residual oil stains (such as polishing fluid), and fine solid particles after the grinding and polishing process of sapphire wafers and other semiconductor materials, as well as after the back grinding and thinning process of LED wafers.
Its formula has undergone repeated research, development and optimization, integrating a variety of special chemical active ingredients. It can perfectly replace acetone, and can quickly dissolve and peel off wax without damaging the precise structure and performance of the chip, ensuring that the chip surface meets extremely high cleanliness standards and providing reliable guarantee for the subsequent manufacturing processes of the chip.
2、Product Features
2.1 Excellent Wax Removal Efficiency It has strong dissolving ability for various common waxes used in chip processing, such as temporary fixing wax. It can quickly penetrate into the interior of the wax, destroy its molecular structure, make it emulsify and disperse quickly, achieve efficient removal in a short time, and significantly improve production efficiency.
2.2 High Material Compatibility It fully considers various sensitive materials involved in chip manufacturing, such as silicon, germanium, aluminum, gallium and their compound semiconductors, as well as various metal wires and insulating layers. The product has undergone a large number of rigorous compatibility tests to ensure that while effectively removing wax, it will not cause corrosion, oxidation, swelling or other physical and chemical damage to any part of the chip, so as to maximize the performance and yield of the chip.
2.3Adopting advanced purification technology and formula design, the ion content of the wax remover itself is extremely low. During and after the cleaning process, almost no ionic impurities will remain on the chip surface, effectively avoiding problems such as chip short circuit, leakage and signal interference caused by ion residue, and meeting the strict requirements of chip manufacturing for ultra-clean environment.
2.4 Adhesive Gas pollution It can reduce the problem of "adhesive gas pollution" to a certain extent by improving the cleanliness of the chip surface.
2.5 Environmental Protection and Safety In the research and development process, it follows the concept of green chemistry, selects environmentally friendly raw materials, and does not contain harmful heavy metals (such as lead, mercury, cadmium, etc.), halogenated hydrocarbons and persistent organic pollutants. The product has a mild odor, and the volatile substances are minimally harmful to human health. It meets the standards of occupational health and safety during use, and also reduces environmental pollution. III. Technical Parameters Appearance: Yellow transparent liquid pH value: 7.5 ---9.5 Density: 0.9350 - 1.030 g/cm³ Boiling point: ≥ 103℃ Flash point: None (non-flammable, safe to use)
3、Scope of Application
It is suitable for cleaning wax deposits, oil stains, dust and grinding fluid/polishing fluid in the production of precision industry products such as semiconductors and optical devices, and can perfectly replace acetone. 4、Cleaning Process Recommendations for Water-Soluble Dewaxing Fluid HF-DW-03A

Remarks:
5.1、The actual cleaning process can be optimized according to the customer's on-site conditions.
5.2、It is used as stock solution directly. The verified service life is 0.35g wax per wafer, with a setting of 100 pieces of 4-inch wafers per liter. Later, it can be optimized according to the actual amount of applied wax and process conditions.
5.3、For Tanks 3 and 4, please use disposable deionized water for sufficient rinsing to remove residual dewaxing fluid.
5.4、When this fluid is heated to 50℃, its color will darken, but this does not affect the cleaning ability, nor will it cause thermal decomposition or other problems. It is a normal phenomenon that the surfactant changes with temperature, and the color will return to normal when it is restored to room temperature.

6、Packaging
Professional chemical HDPE/PP plastic barrels are used, and iron barrels or galvanized barrels are never used to avoid ion pollution to the chip. Specifications: 200 liters and 25 liters.
7、Precautions
Incompatible with strong oxidants and acids.
8、Storage and Transportation
Since this cleaning agent is non-toxic, non-irritating and non-flammable, it can be transported and stored as ordinary chemicals.
Store in a cool, dry and ventilated room in a sealed container, and seal it well after each opening; Avoid strong oxidants, acids, high-temperature environments, direct sunlight, rain, etc., and keep away from fire sources.
9、Shelf Life
The shelf life is one year under the original packaging conditions.
