14. RECOMMENDED SOLDERING CONDITIONS
The
PD780021A(A), 780022A(A), 780023A(A), and 780024A(A)Note should be soldered and mounted under the
following recommended conditions.
For details of the recommended soldering conditions, refer to the document Semiconductor Device Mounting
Technology Manual (C10535E).
For soldering methods and conditions other than those recommended below, contact an NEC Electronics sales
representative.
Note
The
PD780021AY(A), 780022AY(A) (except for the 64-pin plastic QFP (GC-AB8 type)), 780023AY(A),
and 780024AY(A) and the 64-pin plastic LQFP (GB-8EU type) of the
PD780021A(A), 780022A(A),
780023A(A), and 780024A(A) are under development, so their soldering conditions are undetermined.
