15. RECOMMENDED SOLDERING CONDITIONS
It is recommended that the
μ
PD784035Y, 784036Y, 784037Y, and 784038Y be soldered under the following
conditions.
For details on the recommended soldering conditions, refer to information document “Semiconductor Device
Mounting Technology Manual” (C10535E).
For soldering methods and conditions other than those recommended, please consult an NEC representative.
