(2) Reworking with Soldering iron
The following conditions must be strictly followed when using a soldering iron after being
mounted by reflow soldering.
Tip temperature / Soldering time : 350°C max / 3(+1,-0)s
Soldering iron output :30W max
Tip diameter : 3mm
Reworking should be limited to 2 times.
Notes: Do not touch the products directly with the soldering iron.
(3) Solder Volume
Solder shall be used not to be exceeded the upper limits as shown below.
Upper limit

Recommendable
Recommendable
t
1/3 T ≦ t ≦ T (T:thickness of electrodes)
Accordingly increasing the solder volume, the mechanical stress to Chip is also increased.
Exceeding solder volume may cause the failure of mechanical or electrical performance.
13.6 Resin coating
The electric characteristics may change and/or it may affect on the product's performance due to high
cure-stress of resin to be used for coating / molding products. So please pay your careful attention when you
select resin. In prior to use, please make the reliability evaluation with the product mounted in your application
set.
13.7 Attention regarding P.C.B. bending
The following shall be considered when designing and laying out P.C.B.'s.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress due to
warping the board.
