DIRECTIONS FOR USE TECHNICAL SPECIFICATION A fulldescription of test methods and detailedtest results are Soldering with LOCTITE C 511 does not require any special availableon request. methods or deviation from standard hand soldering practices. Alloys :The alloys used for LOCTITE C 511 flux cored solder wires conform to the purity requirements of the common national and international standards. A wide range of wire diameters is available manufactured to close dimensional tolerances. For details refer to document Properties of Alloys used inCored Solder Wires. Flux : LOCTITE C 511 solid flux is based on a blend of carefully selected activators and modified resin. It has a mild rosin odour and leaves a small quantity of clear,paleresidue. TDS LOCTITE C 511 , August -2021 Soldering Iron: Cleaning: Good results should be obtained using a range of tip LOCTITE C 511 flux cored solder wires have been formulated temperatures. However, the optimum tiptemperature and heat to leave paleflux residues and to resist spitting and fuming. In capacity required for a hand soldering process is a function of most industrial and consumer electronics applications,cleaning both soldering iron design and the nature of the task. Care willnot be required. The product may therefore be used to should be exercised to avoid unnecessarily high tip complement a no-clean wave soldering or reflow process or to temperatures for excessive times. A hightip temperature will allow repairs to cleaned boards without the need for a second increase any tendency to flux spitting and itmay produce some cleaningprocess. Ifcleaningis required this is best achieved residue darkening. The soldering iron tip should be properly using LOCTITE MCF800 solvent cleaner (see separate tinned and this may be achieved using LOCTITE C 511 cored technical data sheet). Other proprietary solvent or wire. Severely contaminated soldering iron tips should first be semi-aqueous processes may be suitable. Saponificationmay cleaned and pre-tinned using LOCTITE TTC-LF Tip be suitable but customers must ensure that the desired level of Tinner/Cleaner, then wiped on a clean,damp sponge before cleanliness can be achieved by their chosen system. re-tinning with LOCTITE C 511 cored wire.
