processing guidelines storage & handling
1. Refrigerate to guarantee stability @ 0- 10°c (32-50°f) 2. Shelf life of refrigerated paste is six months. 3. Paste can be stored for 4 weeks at room temperatures up to 25° c (77°f). 4. When refrigerated, warm-up of paste container to room temperature for up to 8 hours. Paste must be 18°c (64°f) before processing. Verify paste temperature is above 18°c (64°f) or greater before setup. Printing can be performed at temperatures up to 28°c (81°f). 5. Do not remove worked paste from stencil and mix with unused paste in jar. This will alter rheology of unused paste. 6. These are starting recommendations and all process settings should be reviewed independently

If the clearance is too little, the dot tends to be flattened out, and if too large, the dot tends tohave long tailing.Pressurethe pressure applied in the syringe should be kept at a minimum, and the proper head pressure kept inthe range of 15-25 lb/in² (1.05-1.76 kg/cm²). In cases where a paste requires much higher pressure(more than 40 lb/in² or 2.82 kg/cm²) to dispense, the paste will become inconsistent and clogging maybe expected. The external air pressure supply should be maintained constant. Paste application solder paste should be taken out of the refrigerator at least 3 to 6 hours prior to use. This will give the-paste enough time to come to thermal equilibrium with the environment. The flow rate of paste in dispensing application depends on viscosity, which can be altered by temperature change. If solder pasteis purchased in syringes pre-mixing is not necessary due to the shear action produced from the dispensing. Reflow best results have been achieved when egpl-6337 is reflowed in a forced air convection oven witha minimum of 8 zones (top & bottom), however reflow is possible with a 4 zone oven (top & bottom). The following is a recommended profile for a forced air convection reflow process. The melting temperature of the solder, the heat resistance of the components, and the characteristics of the pcb (I.E. Density, thickness, etc.) determine the actual reflow profile.

ALPHA CVP-520Solder Paste

ALPHA CVP-520 is designed to enable low temperature surface mount assembly technology. The lead-free alloy in ALPHA CVP-520 has a melting point below 140°C, and has been successfully used with peak reflow profiles between 155°C and 190°C. The flux residue from ALPHA CVP-520 is clear, colorless, and provides excellent electrical resistivity, exceeding industry standards. This product enables the elimination of an extra wave or selective wave soldering process when temperature sensitive through hole components are used in an assembly. Eliminating a wave soldering or selective soldering step can significantly lower the cost of producing an electronic assembly, increase daily throughput, eliminate the need for managing bar solder and wave soldering flux supplies and eliminate the need for pallets.

The carefully selected Sn/Bi/Ag alloy in ALPHA CVP-520 was selected to give the lowest melting point, lowest pasty range during melting and re-solidification, along with a very fine grain structure, offering maximum resistance to thermal cycle based fatigue. The alloy also yields very low voiding BGA solder joints, even when a traditional SAC alloy sphere is used. The use of ALPHA Exactalloy performs may enable the elimination of selective wave soldering by providing additional solder volume when needed. All components used with ALPHA CVP-520 must be lead-free to eliminate the formation of tin/lead/bismuth intermetallic which has a melting point under 100ºC.

Features & Benefits

Enables elimination of a second or third reflow cycle when temperature sensitive components or connectors are used.
Reduces energy consumption in reflow ovens versus standard lead free alloys.
Reduces reflow process cycle time.
Delivers 8 Hour stencil life.
Potential eliminations of bar solder, wave soldering flux and energy costs associated with wave soldering.
Compatible with all commonly used lead free surface finishes (Entek HT; Alpha Star Immersion Silver, Immersion Tin, Ni/Au, SACX HASL, etc.)

Excellent resistance to random solder balling minimizing rework and increasing first time yield.
Low temperature reflow profiles may enable the use of less expensive printed circuit board substrates, when appropriate.
Meets highest IPC 7095 voiding performance (Class III).
Provides excellent electrical reliability properties.
Zero halogen (no halogen intentionally added) and halide-free material.
Compatible with either nitrogen or air reflow.
