PRODUCT DESCRIPTION
Chemical Drag Plus is a low residue rosin core designed specific for soldering application offering the soldering wire suppliers or soldering wire manufacturers to manufacture the Telecore Plus specification LEAD FREE solder wire. That meets all Bellcore specifications.The unique blend of resin flux and proprietary activators provide rapid wetting as leaving minimal, optically clear, completely inert residue. ESSENTIAL FEATURE: The Drag-Plus soldering wire rosin flux core is the best performance, for Telecore Plus LEADFREE solder wire specificiation production. It is highly reliable resin mixture. Its unique activator, with the rapid moisture feature, its chemical core under the melting mode condition still to be able to have the high adhesion performance, surrounded the ironing anvil at the soldering point causing more smooth and effective durring the high density of SMT parts hand soldering process and result in raising the soldering efficiency. Drag-Plus is no clean chemical product , its reliability is very outstand, and conforms to all Bellcore leakage free and the high impedance requirement remained is transparent and the residual ion is inactive, therefore does not need to clean. Use: Drag-Plus is appropriate for all kinds conformance to Bellcore the TR-TSY-000078 requirements for no clean hand soldering application for the soldering wire suppliers and soldering wire manufacturers. Drag-Plus soldering wire core will be possible to be affected in the below micro oxidation on the metal surface, including the common copper surface, OSP copper surface, gilded surface, silver-plating surface and tin-plating surface etc. Residual handling : The Drag-Plus welding residual may be safely remained on the soldering board, reference to Bellcore Specification TR-NWT-000078, Issue 3., if needs certainly to clean, may use the basic organic cleansing agent, the saponifier, or half water characteristic cleansing agent for elimination.
