Reliable and workable in low temperature reflow
Energy-saving
By reducing the required reflow profile temperature, electricity consumption can be reduced by approximately 40% compared to SAC305.
Reduction of electricity consumption results in reduction in CO2 emissions, achieving both energy saving and environmental care.
■ Electricity consumption / hr.during reflow process(kw)
Reduces thermal damage to components and substrate
Energy saving is not the only benefit of a low temperature reflow profile.
A low temperature profile reduces thermal damage to components during double-sided reflow and allows for use of heat-sensitive paper phenolic substrates.
■ Joint conditions after reflow
High insulation reliability
The flux solvent volatilizes even in low temperature reflow, eliminating reduction in insulation resistance arising from inadequate volatilization.
TB48-M742・T4AB48/58-M742 produces flux residue with high insulation reliability.
■ Voltage applied SIR
