TechnicalData Sheet LOCTITE C 502 September -2014 PRODUCT DESCRIPTION Soldering Iron: LOCTITE C 502 provides the following product characteristics: Good results can be obtained using a range of tip temperatures. However, the optimum tip temperature and Technology Solder wire -Cored heat capacity required for a hand-soldering process is a Activity Medium function of both soldering iron design and the nature of Product Benefits No clean the task. Clear residue Care should be exercised to avoid unnecessarily hightip Good wetting temperatures for extensive periods of time. Fast soldering A hightip temperature may increase any tendency to flux Mildodor spitting and it may produce some residue darkening. Pb-freeand SnPb alloys available The tip of the soldering iron should be properly tinned. IPC/J-STD-004 ROM1 Severely contaminated soldering iron tips should be Classification cleaned with Multicore Tip Tinner/Cleaner. Application Soldering Wipe the tip on a clean,damp sponge before re-tinning Surface Finishes Copper ,Brass and Nickel with LOCTITE C 502 wire. Soldering Process: LOCTITE C 502 cored solder wire has been specially 1. Apply the soldering iron tip to the work surface. The iron formulated to complement no clean wave and reflow soldering tip should contact both the base material and the lead at processes. LOCTITE C 502 is also well suited for soldering the same time to heat both surfaces properly. It should applications requiring highmeltingtemperature alloys . take no more than a fraction of a second to heat both surfaces adequately. TYPICAL PROPERTIES 2. Apply LOCTITE C 502 flux cored wire to a part of the joint surface away from the soldering iron and allow to form a Solder Cored Wire joint fillet. This will be virtually instantaneous. Do not Alloys -Tin/lead SN63 apply excessive solder to the joint as this will not improve joint integrity and it will leave excess flux residues on the SN60 surface. SN62 Alloys -Lead Free 96SC(SAC387) 3. Remove solder from the work piece and then remove the 97SC(SAC305) iron tip. 99C(SnCu) 4. The total process will be very rapid, depending upon 95A (SnSb) thermal mass, tip temperature, tip configuration and the 96S(SnAg) solderability of the surfaces to be joined. AcidValue 156 to 172 mg KOH/g 5. The resin and flux systems are designed to leave Halidecontent 0.2% relatively low residues and to minimizeresidual activity. Flux Content (%) 2.7 This is achieved by ensuring some decomposition and volatilization takes place during the soldering process ALLOYS: The alloys used inLOCTITE C 502 cored solder wires conform Cleaning: to the purity requirements of the common national and LOCTITE C 502 flux cored solder wire has been formulated to international standards . leave amber flux residues and resist spitting and fuming. In most industrial and consumer electronics applications, FLUX: cleaning will not be required. The product may, therefore, be LOCTITE C 502 solid flux is based on modifiedrosin and used to complement a no-clean wave soldering or reflow carefully selected activators. Inpractice they exhibit a mild process or to allow repairs to cleaned boards without the need rosin odor and leave a small quantity of clear residue . for a second cleaningprocess. Inhigh-reliabilityapplications, the residues should be removed. DIRECTIONS FOR USE Soldering with LOCTITE C 502 does not require any special Should cleaning be required, this is best achieved using methods or deviation from standard hand soldering practices.
