However, the optimum tip the Material Safety Data Sheet, (MSDS). temperature and heat capacity required for a hand soldering Note process is a function of both soldering iron design and the The data contained herein are furnished for information only and nature of the task and care should be exercised to avoid are believed to be reliable. We cannot assume responsibility for unnecessarily high tip temperatures for excessive times. A the results obtained by others over whose methods we have no high tip temperature will increase any tendency to flux control. It is the user s responsibility to determine suitability for spitting and it may produce some residue darkening. the user s purpose of any production methods mentioned herein The soldering iron tip should be properly tinned and this and to adopt such precautions as may be advisable for the may be achieved using Multicore cored wire. Severely protection of property and of persons against any hazards that contaminated soldering iron tips should first be cleaned and may be involved in the handling and use thereof. In light of the pre-tinned using Multicore Tip Tinner Cleaner, then wiped foregoing, Henkel Corporation specifically disclaims all on a clean, damp sponge before re-tinning with Multicore warranties expressed or implied, including warranties of merchantability or fitness for a particular purpose, arising cored wire. from sale or use of Henkel Corporations products. Henkel Corporation specifically disclaims any liability for Soldering process: Multicore cored wires contain a consequential or incidental damages of any kind, including careful balance of resins and activators to provide clear lost profits. The discussion herein of various processes or residues, maximum activity and high residue reliability, compositions is not to be interpreted as representation that they without cleaning in most situations. To achieve the best are free from domination of patents owned by others or as a results from Multicore solder wires, recommended working license under any Henkel Corporation patents that may cover such practices for hand soldering should be observed as follows: processes or compositions. We recommend that each prospective user test his proposed application before repetitive use, using this x Apply the soldering iron tip to the work surface, data as a guide. This product may be covered by one or more ensuring that it simultaneously contacts the base United States or foreign patents or patent applications. material and the component termination to heat both surfaces adequately. This process should only take a fraction of a second. x Apply Multicore flux cored solder wire to a part of the joint surface away from the soldering iron and allow to flow sufficiently to form a sound joint fillet this should be virtually instantaneous. Do not apply excessive solder or heat to the joint as this may result in dull, gritty fillets and excessive or darkened flux residues. x Remove solder wire from the work piece and then remove the iron tip. The total process will be very rapid, depending upon thermal mass, tip temperature and configuration and the solderability of the surfaces to be joined. Multicore flux cored solder wires provide fast soldering on copper and brass surfaces as well as solder coated materials. The good thermal stability of Multicore fluxes means they are also well suited to soldering applications requiring high melting temperature alloys. Cleaning: Multicore X39 flux cored wires have been formulated to leave minimal quantities of flux residue and to resist spitting and fuming. Cleaning will not be required in most situations but if necessary this is best achieved using Multicore MCF800 Cleaner (see separate technical data sheet). Other proprietary solvent or semi-aqueous processes may be suitable. Saponification may be viable but customers must ensure that the desired level of cleanliness can be achieved by their chosen system.
