Micronox® MX2302 is an engineered semi-aqueous solvent blend designed to remove difficult flux and paste residues including lead-free, rosin, no-clean, and tacky flux from wafer bumps found in flip chip, chip scale and µBGA packages.
Micronox MX2302 is a highly dispersive cleaning agent engineered to remove organic acid, rosin and no-clean flux residues. Micronox MX2302 is a bio-based, environmentally friendly, naturally derived, biodegradable cleaning agent. The key ingredient within Micronox MX2302 comes from corn cobs, oat hull and sugar cane biomass extracts. Micronox MX2302 has superior solvency for carboxylic acid structures, rosins, resins and ionic contaminants.
Micronox MX2302 has a low vapor pressure, which reduces concerns of flammability and smell. The molecular structures used within the engineered composition provide a dispersive, polarity and hydrogen bonding balance. The dispersive driver provides strong solubility with rosin and resin structures. The polarity driver provides Van der Waals forces of attraction for mild acidic soils. The hydrogen bonding driver provides water solubility and the ability to remove ionic contaminates. These forces work in combination to form the ideal electronic assembly and packaging cleaning agent.
Micronox MX2302 is highly effective at removing baked-on flux residues. This property is beneficial when cleaning lead frames, packages and high-lead alloys. The low surface tension of 20-26 dynes/cm improves cleaning under the Z-axis of the component or package. Micronox MX2302 is designed to be processed in semi-aqueous centrifugal, spray under immersion, ultrasonic and mega-sonic tools.
A major benefit of Micronox MX2302 is its complete water solubility. This enhances the ease of rinsing and removal of ionic contamination. Micronox MX2302 is buffered to maintain a stable pH over a wide level of flux loading. The flash point of this product ranges from 163-183°F, depending on the flash point method used. Micronox MX2302 has been used within industry for over 20 years and has a long heritage of successful use. Micronox MX2302 is compatible with most materials of construction and metallic alloys.
