No-Clean Solder Pastes Class

SynTECH

Data Sheet (PDF)

MSDS (PDF)

 

The SynTECH series solder paste is a synthetic poly-adduct designed to exeed requirements for reliable solder joints in SMT PC board assemblies. This paste was formulated to replace traditional rosin/resin based no-clean formulations with more reliable synthetic materials. The residue is pin probable for ICT inspection. The SynTECH series does not require refrigeration if left at room temperature for 6 months and has a 12-month refrigerated shelf life. This formula is also available with a U.V. tracer for easier flux splatter inspection. (SynTECH-UV)
