ALPHA 100树脂助焊剂

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.
