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，皓宇爱法助焊价格， 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，爱法助焊笔， when tested according to the method developed by Philips-Eindhoven， Netherlands，爱法助焊笔功能， “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， 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.

助焊笔的使用要点
1.焊接前，在母材上涂抹助焊剂（提高浸润性）；2.通过向修正时的对象物涂抹助焊剂，可除去氧化腊并提高浸润性；3.可用酒精等溶剂清洗基板（禁止使用有机溶剂）。
助焊笔的优点.1、操作方便易于携带；2.可重复加注助焊剂；3.防止助焊剂挥发，保证助焊剂特性不变；4.特殊结构设计，笔蕊储存助焊剂液体，绝不外泄渗漏；5.避免人体皮肤接触有机溶剂，实用性安全可靠；
