Temperature (°C) The Model SA Series breaker is designed for reflow and hand soldering. It is not designed or warranted for flow soldering. The following conditions must be adhered to: Hand Soldering: Place a solder iron on each of the terminal ends for 5 seconds at +350 °C, followed by positioning the breaker in ambient temperature of +25 °C for 8 hours. 270 240 210 180 150 120 90 60 30 0 Recommended Reflow Profile TEMPERATURE _ TIME 150 ~ 180 °C ..... 100 ~ 150 Seconds ≤220 °C ..... 20 ~ 40 Seconds 245 °C ..... Peak 0 60 120 180 240 300 360 Time (Seconds) Do not expose the breaker to temperatures exceeding +260 °C. Recommended Land Pattern 0.6 (.024) 0.9 (.035) 9.0 (.354) 1.6 (.063) 5.8 (.228) 1.6 (.063) Recommended Mask Thickness: 0.12 mm 2.4 (.094) Recommended Solder Particle Size: 30 µm 0.9 (.035) DIMENSIONS: MM (INCHES) Mounting Cautions In order to protect the housing and mechanical parts inside from deformation, prevent excessive load at the time of part absorption / part deployment and mounting. A part absorption nozzle more than 2 mm in diameter with a 3 N (5 N max.) mounting load is recommended. Any shock to the product by the nozzle during the mounting procedure may have a negative influence on the function of the breaker. Specifications are subject to change without notice.
