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.

KVS 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. KVS no-clean solder pastes have a stencil life of >8 hours.
