ALPHA 100松香助焊劑
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 wher current leakage is extremely sensitive and wher 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.
