Solder Paste - Lead-Free RoHS
Alpha lead-free solder pastes (RoHS) are formulated to provide exceptional printing and superior wetting with low voiding.
Alpha RoHS lead-free solder pastes are stocked in SAC305 alloy containing 96.5% Tin/ 3.0% Silver / 0.5% Copper. Most Alpha SMT pastes are halide-free for the highest level of cleanliness whether you are cleaning post-soldering residues or utilizing a no-clean process.
Some formulas are available in Type 4 powder size for ultra fine-pitch printing. Type 3 Alpha pastes are suitable for printing applications down to 16 mil (0.4 mm) pitch QFP components and 12 mil BGA circles using a 5 mil thick laser cut stencil.
Alpha lead-free solder pastes have the longest stencil life available to provide consistent printing for up to 5 hours at temperatures from 20 - 28° C.Alpha no-clean solder pastes have a stencil life of >8 hours.
