Solder paste:
solder paste is a design for today's SMT production process no-clean solder paste. Minimal amount of oxidation using lead-free alloys and inactive better help paste formulated, viscosity can meet the printing and dispensing technology, wide range of applications.
★adapt to a variety of electronic circuit boards installed linking the various sectors of lead-free soldering processes.
★adapt to a variety of lead-free solder dip tin or components.
★but also for a variety of special process of welding.
★It also can be deployed to meet customer production of lead-free solder according to the customer's actual production.
Benefits:
★Using a dedicated help paste formulation which very little residue, and the light color.
★weldability strong, good welding can be welded in a variety of coating surface.
★choose a variety of packaging: copper needle type and canned.
★can adjust for special welding flux paste.
