Type: Organic pH: No state: Solid Ingredient: Lead Free Performance: High Temperature base: Rosin Trademark: ELECTROLOY Transport Package: 0.5kg/Jar Specification: SN100C Origin: China/Malaysia/India HS Code: 3810100000 Product Description product descriptionELECTROLOY and FCT Asia Co., Ltd. have signed an agreement to jointly manufacture SN100C solder alloy based on the related patents of NIHON SUPERIOR.ELECTROLOY's EMCO # 265HF-SN100C no-clean solder paste is a rosin-based, halide-free solder paste with an alloy composition containing tin, copper, nickel and germanium. SN100C has many excellent welding qualities. In the international electronics industry, this alloy has established itself as one of the most popular lead-free metals. Adding nickel to the registered tin-copper eutectic, the germanium method can provide the following advantages:feature:1. Low-cost lead-free alloy2.Low residue3.Bright and smooth welding interface without cracks4.Excellent through-hole penetration5.Reduce copper corrosion6.Reduce damage to stainless steel and tin furnaces7.Close to eutectic point8.Easy to maintain alloy compositionChemical composition of the alloyThe alloy composition of EMCO # 265HF-SN100C lead-free solder paste is strictly controlled in the following SN100C specifications:AppearanceEM # 265HF-SN100CP lead-free solder paste appears as a gray uniform paste.Tin powder particlesThe size of the solder particles is based on the international standard IPC J-STD-005.weightinthesample%Nominalsize3Nominalsize4Lessthan1%ofsamplesizeGreaterthan45microns38micronsAtleast80%ofsamplessize45-25microns38-20micronsUpto10%ofsamplessizeLessthan20microns 20micronsEM # 265HF-SN100CP Lead-free solder paste reflow temperature curWarm upHeat from room temperature to 140-150 ° C at a rate of 1-2 ° C per second. Faster speeds can cause component rupture due to evaporation of adsorbed moisture.Soaking zoneBetween 150 and 200 degrees Celsius. The soaking zone is used to level the temperature difference on the PCB. It is often used in PCBs with large differences in infrared furnaces and components and copper distribution.Speed up to refluxMaximum 2 degrees Celsius per second due to different thermal expansion rates inside the element.ReflowPeak temperature is related to component specifications. The peak temperature is between 240-245 degrees Celsius in 5-8 seconds, and is higher than 227 degrees Celsius in 40-80 seconds.cool downMaximum 3 degrees Celsius per second due to different thermal expansion rates inside the element.CleanMisprints can be wiped with commercially available solvent cleanersAfter cleaning, EMCO#265HF-SN100CP residue can be left on the circuit board for reflow. If cleaning is required, a commercially available solvent cleaner can be used.Stencil cleaning It is recommended to wipe with a commercially available screen cleaner wax paper.packageEach can of solder paste weighs about 500 grams and should be tightly sealed. The label should be accompanied by the product number, alloy composition, particle size, net weight and product batchRelated information. Solder tin cans should be placed in foam boxes and packed in cardboard boxes, each box weighing approximately 10 kg. Cartridge-type solder pastes of 600 or 1000 grams are available.Storage and shelf lifePlease store below 3-10degrees Celsius. The validity period of the solder paste is within six months from the production date. Before using the solder paste, it needs to warm up for about 4 hours before use. Before putting the solder paste on the template, use a spoon to stir the solder paste for 1-2 minutes or the solder paste mixer for 30-60 seconds.ShipA certificate of analysis is attached to the shipment.Material Safety Data SheetProduct MSDS / SDS can be obtained from sales department.Lead-free low-temperature alloys:Alloy numberAlloy compositionFuseFeatureApplicationLF-302Sn42 / Bi58138°C Reasonable shear strength and fatigue resistance.
