6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS

• A: Temperature axis

• B: Time axis

• C: Liquidus temperature: 217 to 220°C

• D: Ramp-up slope: 1 to 3°C/s

• E: Duration of constant temperature: 60 to 120s; the range of constant tem-

perature: 150 to 200°C

• F: Duration above the liquidus: 50 to 70s

• G: Peak temperature: 235 to 245°C

• H: Ramp-down slope: 1 to 4°C/s

Note: The above curve is just an example of the solder paste SAC305.

For more details about other solder pastes, please refer to Recommended

oven temperature curve in the solder paste speciﬁcations.

Manner 2: Wave soldering process (Oven temperature curve of wave sol-

dering)

Set oven temperatures according to the following temperature curve of wave sol-

dering. The peak temperature is 260°C±5°C.
