ALPHA 100松香助焊剂
Non-Activated Rosin Flux (Type R)

GENERAL DESCRIPTION 
ALPHA 100 Flux is a solution of pure water-white rosin in alcohol, meeting the requirements of Type R of MIL-F-
14256D, designated as "Flux, Soldering, Liquid (Rosin Base)."  This flux contains no activator additives, making this the least corrosive type of rosin flux available. 
USES 
ALPHA 100 can be used on critical electronic assemblies where current leakage is extremely sensitive and where flux residue removal is not feasible.   This flux is often used to test the solderability of bare boards and component leads, as an incoming QC tool. ALPHA 100 is suitable for use on the following metals, provided the surfaces are not heavily tarnished: 
 
Cadmium (Plate)  Tin (Hot Dipped) 
Copper   Tin Plate (Electrolytic) 
Gold    Tin/Zinc (Plate) 
Silver    Terne (Plate) 
Solder (Plate) 
 
ROSIN TYPE 
ALPHA 100 Rosin Flux contains P.C. Rosin - a quality grade of water-white rosin that meets the requirements of Class A of Type 1, Grade WW of Federal Specification LLL-R-626.  Use of P.C. Rosin insures a flux of maximum clarity, light color, and consistent performance. 
 
RESIDUE PROPERTIES 
Flux resides are non-conductive and non-hygroscopic and are, therefore, considered to be non-corrosive.  While it is recommend that flux residues be removed after soldering for critical assemblies, no corrosion or current leakage will occur if some residues remain. 
 
RESIDUE REMOVAL   
For effective removal flux residues, Alpha solvent cleaners 564, 565 or 1003 can be used; for aqueous cleaning 
systems, Alpha 2100 can be used.
