Surface Mount Recommendations

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:

Reflow Soldering:

The recommended reflow soldering

conditions are as follows:

150 ~ 180 °C ............... 100 ~ 150 seconds

≤220 °C........................ 20 ~ 40 seconds

255 ~ 260 °C ............... 5 ~ 10 seconds

Process breaker in a reflow furnace using

the profile shown above three times,

followed by positioning the breaker in

ambient temperature of +25 °C for 8 hours.

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.

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.
