Technical Data Sheet Multicore Solder Cored Wire Flux 362 & 366 June 2004 ROSIN BASED CORED SOLDER WIRE FLUXES SPECIAL PROPERTIES Surface Insulation Resistance: Multicore 362 and 366 flux Properties of Multicore 362 and 366 solid fluxes for cored pass the J-STD-004 SIR test and other elements of J-STD- solder wire: 004 test protocols associated with the flux classification ROL1 Good wetting on most common surfaces for 362 and ROM1 for 366. Two activity levels: Multicore 362 for general work and Electromigration Test: Multicore 362 and 366 pass the Multicore 366 for more difficult surfaces Bellcore GR-78-CORE Electromigration tes Non-corrosive Fast soldering RECOMMENDED OPERATING CONDITIONS Rosin based Soldering iron: Good results should be obtained using a Halide activated range of tip temperatures. However, the optimum tip temperature and heat capacity required for a hand soldering PRODUCT RANGE process is a function of both soldering iron design and the Multicore 362 and 366 cored wires are manufactured with a nature of the task and care should be exercised to avoid range of flux contents. Although users will normally be using unnecessarily high tip temperatures for excessive times. A products with a nominal flux content of 3%. high tip temperature will increase any tendency to flux spitting Multicore 362 and 366 cored wires are available in a variety of and it may produce some residue darkening. alloys conforming to J-STD-006 and EN 29453 or alloys conforming to similar national or international standards. For The soldering iron tip should be properly tinned and this may details refer to document Properties of Alloys used in Cored be achieved using Multicore cored wire. Severely Solder Wires. A wide range of wire diameters is available. contaminated soldering iron tips should first be cleaned and Alternative flux contents and alloys may be manufactured to pre-tinned using Multicore Tip Tinner/Cleaner TTC1, then special order. wiped on a clean, damp sponge before re-tinning with Multicore cored wire. TECHNICAL SPECIFICATION A full description of test methods and detailed test results are Soldering process: Multicore cored wires contain a careful available on request. balance of resins and activators to provide clear residues, maximum activity and high residue reliability, without cleaning Alloys: The alloys used for Multicore flux cored solder wires in most situations. To achieve the best results from Multicore conform to the purity requirements of the common national and solder wires, recommended working practices for hand international standards. A wide range of wire diameters is soldering should be observed as follows: available manufactured to close dimensional tolerances. For Apply the soldering iron tip to the work surface, ensuring details refer to document Properties of Alloys used in Cored that it simultaneously contacts the base material and the Solder Wires . cmponent termination to heat both surfaces adequately. This process should only take a fraction of a second. Flux: Multicore 362 and 366 solid flux leave dry and non-sticky Apply Multicore flux cored solder wire to a part of the joint residues. In use its odour is typically that of rosin fluxes. surface away from the soldering iron and allow to flow sufficiently to form a sound joint fillet this should be TYPICAL FLUX PROPERTIES virtually instantaneous. Do not apply excessive solder or Test 362 366 heat to the joint as this may result in dull, gritty fillets and Acid value 170mgKOH/g 158mgKOH/g excessive or darkened flux residues. Halide content <0.5% 1.0% Remove solder wire from the work piece and then remove SIR Test the iron tip. (without cleaning) The total process will be very rapid, depending upon thermal J-STD-004 Pass Pass mass, tip temperature and configuration and the solderability of the surfaces to be joined.

We recommend that each prospective user test his proposed application before repetitive Health Hazards and Precautions: Inhalation of the flux fumes use, using this data as a guide. This product may be covered by given off during soldering should be avoided. The fumes are one or more United States or foreign patents or patent applications. irritating to the throat and respiratory system. Prolonged or repeated exposure to rosin or modified rosin based flux fumes may lead to the development of respiratory sensitisation and occupational asthma. Multicore solder wires must always be used with suitable fume extraction equipment to remove fumes from the breathing zone of operators and the general work environment. Solder alloys containing lead give off negligible fume at normal soldering temperatures up to 500 C. Normal handling of lead alloy wires will not cause lead to be absorbed through the skin. The most likely route of entry is through ingestion but this will not be significant if a good standard of personal hygiene is maintained. Eating, drinking and smoking should not be permitted in the working area. Hands should be washed with soap and warm water after handling solder wire.
