Environmentally friendly, non-toxic, biodegradable liquid cleaner used for micro-cleansing of LEDs.

Description:
NuGeneration Technologies’ Clean-N-Clear II is an environmentally friendly, non-toxic, biodegradable liquid cleaner used for decontaminating and micro-cleansing LED arrays.  Clean-N-Clear II eliminates amphoteric bicarbonate and alkali carbonate residues embedded in silicone and urethane flash layers during the selective, flash layer removal blasting process.  Additionally, Clean-N-Clear II eliminates particulate contaminants, chemical and mineral deposits, as well as other metal and ionic contaminants.  Clean-N-Clear II is a solvent-free formula.

Characteristics:
Clean-N-Clear II was formulated to selectively remove amphoteric bicarbonate and alkali carbonate residues from LED arrays.  During the array manufacturing process, silicone or urethane flash need to be selectively removed via a targeted blasting process in order to expose the contact pads that were covered during the initial flash layer application.  Clean-N-Clear II will remove these residues from the array without damaging the silicone or urethane flash layer, contact pad/trace layer (Gold/Silver, Nickel, Copper), solder mask, or the MCPCB (Aluminium).  Clean-N-Clear II also removes particulate contaminants, chemical and mineral deposits, and other metal and ionic contaminants from the array.  Clean-N-Clear II  contains no environmentally hazardous solvents such as aromatic solvents, TCE, or PERC, or harsh, hazardous acids such as HF/HCl/H3PO4/H2SO4/HNO3.

Directions for Use:
Clean-N-Clear II is effective at ambient temperatures.  However, it is normally used at 5-20% by volume of water at 25°C to 60°C (77°F to 140°F) for 5 seconds to 2 minutes.  The parameters can vary due to the type and extent of soils to be removed.  Since amphoteric bicarbonate and alkali carbonates are very slowly soluble in water itself, the use concentration of 20% by volume of water is the optimal concentration to run Clean-N-Clear II in order to get the most use and highest loading out of each bath.  This 20% by volume of water concentration has been empirically shown to synergistically optimize the dissolving power of the Clean-N-Clear II and the natural water solubility of the amphoteric bicarbonate and alkali carbonate contaminants being removed.  Please refer to the Clean-N-Clear II - Titration Procedure for more information on bath maintenance, control, and optimization.
