Frequently Asked Questions

What is the melting point of SAC305 solder?

SAC305 solder has a solidus temperature of 217 °C and a liquidus temperature of 219 °C. This means the alloy melts over a temperature range of 217–219 °C rather than at a single eutectic temperature.

Is SAC305 available in tape and reel?

Yes, SAC305 solder spheres are available in tape-and-reel packaging in diameters from 0.300 mm to 0.760 mm. The packaging uses 8 mm polycarbonate carrier tape compatible with EIA-481-E and 13-inch reels containing a standard 20,000 spheres per reel. The minimum order is one reel.

Where can I buy SAC305 solder spheres in small quantities?

You can buy EasySpheres SAC305 solder spheres in small quantities through the website, with a minimum order of 10,000 spheres. Most in-stock orders placed before 2:00 PM Pacific ship the same day; otherwise, they ship within 24 hours.
