SAC Alloys

LEAD-FREE SAC ALLOYS

SAC305, SAC387, SAC405, SAC0307

DESCRIPTION

SAC Alloys are the leading alloys replacing tin-lead solders for electronic assembly applications. These alloys have proven to perform well in surface mount, wave soldering, and hand soldering applications. SAC Alloys may be used with existing equipment, processes, coatings, and flux chemistries. SAC Alloys are available in bar, cored wire, solid wire, foil, preforms, powder, and no-clean, water soluble and RMA solder pastes.

FLUX COMPATIBILIY 

SAC Alloys are compatible with most major electronic grade fluxes on the market today, and are available in paste and wire form in no-clean, water soluble and rosin chemistries. 

TEMPERATURE REQUIREMENTS

APPLICATION

RECOMMENDED TEMPERATURE

REFLOW SOLDERING

PEAK TEMPERATURE 235°-245°C (455°-473° F)

WAVE SOLDERING

POT TEMPERATURE OF 265°-270°C (520°-530°F)

HAND SOLDERING

TIP TEMPERATURE OF 370°-425°C (700°-800°F)

 

STORAGE & SHELF-LIFE

When stored properly these alloys have no limited shelf-life. Surface oxidation is cosmetic and will not impede product performance. 

SAFETY

Use with adequate ventilation and proper personal protective equipment. Refer to the Safety Data Sheet for any specific emergency information. Do not dispose of any hazardous materials in non-approved containers.
