SAC305 Lead-Free Wave Solder Bar
SAC305 is a tin-silver-copper wave solder bar and one of the most widely qualified lead-free alloys. Its silver content makes it more expensive than tin-copper alloys, so it fits best where a specification calls for it.

Questions
What is the melting point of SAC305?
SAC305 melts over a narrow range of 217–220°C. Wave solder pots typically run it at 255–265°C.
Why is SAC305 more expensive than Sn100Ge?
SAC305 contains 3% silver, and silver costs far more than tin or copper. That raises the price per pound of bar.
When should I choose SAC305?
Choose SAC305 when your customer, design authority or certification specifies it, or when a technical review shows a measurable benefit for your product.
