ALPHA 615 SERIES Super RMA Flux
1 Test conducted using oxidized copper and 60Sn/40Pb
flowed at 500°F for 15 seconds.
2 Test conducted using oxidized copper， 60Sn/40Pb at 500°F，
5 mm immersion depth and 10 second cycle time. Wetting
speed measured as time for wetting to reach equilibrium.
Alpha 615 has also demonstrated the ability to prevent solder icicle formation，苏州alpha助焊笔， when tested according to the method developed by Philips-Eindhoven， Netherlands， “Determination of the Flux Efficiency to Prevent Formation of Icicles (and Bridges).”
USE
Alpha 615 is designed for wave soldering printed circuit assemblies that must use an RMA flux meeting military specifications. While formulated to have excellent foaming properties， wave and spray fluxing can also be used.
All three solids levels of 615 flux should be maintained by periodic measurement of flux specific gravity (corrected to 77°F) and kept to within +0.015 and -0.005 of the nominal values.
While preheat temperatures of 180-200°F are sufficient for 615 flux activation，苏州助焊笔厂商， higher preheat conditions may be required for assemblies that have significant heat sinking characteristics， or when attempting to minimize the temperature gradient that ceramic chip components see between preheat and the solder wave.
Under conditions of extreme preheat， most RMA fluxes become extremely difficult to clean after soldering， especially with mild fluorocarbon-blend solvents. Alpha 615 flux residues clean very well with either mild fluorocarbon-blend solvents or aqueous saponifier (Alpha 2110).
PACKAGING
Alpha 615 series fluxes are available in 1， 5 and 55 gallon containers.
HEALTH&SAFETY
Alpha 615 is flammable. Keep away from heat， sparks and open flames. Observe standard precautions for handling and use， such as in well-ventilated areas and avoidance of prolonged or repeated contact with skin.
