ALPHA® TELECORE PLUS NO-CLEAN WIRE SOLDER GENERAL DESCRIPTION
ALPHA Telecore Plus is a low residue core solder designed for no-clean soldering applications that must meet all appropriate Bellcore specifications. The unique blend of rosin and proprietary activators provide rapid wetting while leaving minimal, optically clear, completely inert residue. USES ALPHA Telecore Plus is suitable for use in any commercial no-clean hand soldering application that must meet Bellcore Specification TR-NWT-000078. ALPHA Telecore Plus' activator system is effective in soldering to mildly oxidized surfaces of the following metals: Cadmium (Plate) Solder (Plate) Copper Solder (Hot Dip) Gold Tin (Hot Dip) Silver Tin (Plate) RESIDUE REMOVAL ALPHA Telecore Plus residues can be safely left on the board per Bellcore Specification TR-NWT-000078. If required, residues can be readily removed using Alpha solvents, saponifiers or semi-aqueous cleaners. COMPANION LIQUID FLUX PRODUCT If you choose to use a companion liquid flux, NR205 is recommended in order to provide the optimal combination of high long-term reliability and low residue level. NR205 is available in Alpha's Write Flux flux pens for precise flux application. TECHNICAL SPECIFICATIONS Physical Properties Typical Values Softening Point 71°C (160°F) Rosin Grade WW per Fed. Spec.
