Ürün Açıklaması
product descriptionElectroloy's The EMCO # 502-307P no-clean solder paste is specially designed for lead-free soldering. It uses high shear resistance ingredients and provides excellent printing capabilities. This flux can withstand high preheat temperatures and does not change color. EMCO # 502-307P is made for high-speed printing operations. EMCO # 502-307P provides excellent wetting and soldering on most circuit boards including OSPs, reducing the formation of solder balls and solder beads.
feature:1.Excellent printing capabilities-for ultra-fine pitch welding operations
2.Relaxed reflow-process to increase production
3.Reduction of Tin Beads-Minimizing Rework

Tin powder particlesThe size of the solder particles is based on the international standard IPC J-STD-005.
weight in the sample% | Nominal size 3 | Nominal size 4 |
Less than 1% of sample size | Greater than 45 microns | 38 microns |
At least 80% of samples size | 45-25 microns | 38-20 microns |

EMCO#502-307P Lead-Free Solder Paste Reflow Temperature Curve
Warm 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 ° C due to different thermal expansion rates inside the element.ReflowPeak temperature is related to component specifications. In 5-8 seconds, the peak temperature is between 240-245 degrees Celsius, and 40-80 seconds is higher than 220 degrees Celsius.cool downMaximum 3 ° C due to different thermal expansion rates inside the element.CleanMisprints can be wiped with commercially available solvent cleaners
After cleaning,EMCO#502-307P
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 batch
Related 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 3-10 degrees 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.
