ALPHA® OM-338 Series ULTRA FINE FEATURE LEAD-FREE SOLDER PASTE DESCRIPTION ALPHA OM-338 is a lead-free, no-clean solder paste designed for a broad range of applications. ALPHA OM-338’s broad processing window is designed to minimize transition concerns from tin/lead to lead free solder paste. This material is engineered to deliver the comparable performance to a tin lead process.* ALPHA OM-338 yields excellent print capability performance across various board designs and, particularly, with ultra fine feature repeatability (11 mil Squares) and high throughput applications. Outstanding reflow process window delivers good soldering on CuOSP with excellent coalescence on a broad range of deposit sizes, exceptional random solder ball resistance and mid-chip solder ball performance. ALPHA OM-338 is formulated to deliver excellent visual joint cosmetics. Additionally, ALPHA OM-338’s capability of IPC Class III for voiding and ROL0 IPC classifications ensures maximum long-term product reliability.
FEATURES & BENEFITS • Maximizes reflow yield for lead-free processing, allowing full alloy coalescence at circular dimensions as small as 0.25mm (0.010”) with 0.100mm (4mil) stencil thickness. • Excellent print consistency with high process capability index across all board designs. • Print speeds of up to 200mm/sec (8”/sec), enabling a fast print cycle time and a high throughput. • Wide reflow profile window with good solderability on various board / component finishes. • Excellent solder and flux cosmetics after reflow soldering • Reduction in random solderballing levels, minimizing rework and increasing first time yield • Meets highest IPC 7095 voiding performance classification of Class III. • Excellent reliability properties, halide-free material • Compatible with either nitrogen or air reflow PRODUCT INFORMATION Alloys: SAC305 (96.5%Sn/3.0%Ag/0.5%Cu) SAC387 (95.5%Sn/3.8%Ag/0.7%Cu) SAC396 (95.5%Sn/3.9%Ag/0.6%Cu) SAC405 (95.5%Sn/4.0%Ag/0.5%Cu) SACXTM e1 alloys per JESD97 Classification For other alloys, contact your local Cookson Electronics Sales Office. Powder Size: Type 3, (25-45μm per IPC J-STD-005) and Type 4 (20-38μm per IPC J-STD-005) – Residues: Approximately 5% by (w/w) Packaging Sizes: 500 gram jars, 6” & 12” cartridges, DEK ProFlow TM cassettes, and 10cc and 30cc dispense syringes. Flux Gel: OM-338 Flux Gel is available in 10cc and 30cc syringes for rework applications. Lead Free: Complies with RoHS Directive 2002/95/EC.
APPLICATION Formulated for both standard and fine pitch stencil printing, at print speeds of between 25mm/sec (1”/sec) and 200mm/sec (8”/sec), with stencil thickness of 0.100mm (0.004”) to 0.150mm (0.006”), particularly when used in conjunction with ALPHA® Stencils. Blade pressures should be 0.16-0.34 kg/cm of blade (0.9 -2Ibs/inch), depending upon the print speed. The higher the print speed employed, the higher the blade pressure that is required. The reflow process window will give high soldering yield with good cosmetics and minimized rework. SAFETY While the ALPHA OM-338 flux system is not considered toxic, its use in typical reflow will generate a small amount of reaction and decomposition vapors. These vapors should be adequately exhausted from the work area. Consult the MSDS for additional safety information. STORAGE ALPHA OM-338 should be stored in a refrigerator upon receipt at 0 to 10°C (32-50°F). ALPHA OM-338 should be permitted to reach room temperature before unsealing its package prior to use (see handling procedures on page 2). This will prevent moisture condensation build up in the solder paste.

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.

ALPHA® OM-338 and OM-338T Paste Flux NO-CLEAN REWORK AND BGA FLUX This No-Clean flux is engineered to be used in the placement and reflow of lead-free solders for BGA attach processes. Before reflow, the flux provides sufficient tack to hold the BGA in place. After reflow the residue is clear, colorless. This paste flux can also be used in the rework of components.

The initial ramp rate should be 1 - 2C per second. If necessary, a dwell of 1 to 2 minutes at 130 - 160C is acceptable. Following this equilibrating period is a ramp of 60 - 120C to a peak temperature of 235 - 260C depending upon alloy. The time above alloy liquidus (TAL) should be 45 - 90 seconds. Cooling rate should be 3 - 7C per second to room temperature. USE The flux may be applied by screen printing or pin transfer (substrate) or doctor blade / dip coating (package). It can also be dispensed. CLEANING Although designed as a no-clean flux system, the reflowed residue may be cleaned with BIOACT SC-10E, BIOACT SC-30, ALPHA SM-110, ALPHA SM-110E, ALPHA BC-2200, Kyxen Micronox MX2501, and Zestron ATRON® AC205. Production stencils or pin transfer equipment can be cleaned with BIOACT SC10. STORAGE The flux should be stored in sealed containers and need not be refrigerated. Shelf life of unopened containers is 6 months. If the material has been chilled, the container should be allowed to reach room temperature before opening in order to prevent moisture condensation from ambient air onto the flux.  
SAFETY While OM-338 and OM-338T paste flux is not considered toxic, its use in typical reflow processes will generate some decomposition and reaction vapors. These vapors should be adequately exhausted from the work environment and away from personnel. Consult the Material Safety Data Sheet (MSDS) for additional safety information. For the latest MSDS,
