6. Prohibitions and precaution for handling
6.1 Reflow soldering condition
Issue No.
20090853
6/8
1) Two times max. with directing the switch mounting side of P.W.B up.
2) Re-soldering by soldering iron shall be allowed under 350℃ max. 3 sec. max. 1 time only
and the tip of iron must not touch to terminals.
Soldering iron for re-soldering have to be 60W max.
6.2 Design instructions
1) Please refer to the land pattern plan Panasonic recommends on the 2nd page.
2) Design key top as fig-1. Design inclination of key top 4 deg. max. as fig-2.
Tolerance between switch and key top is within 0.3mm.
(Recommended operation condition)

fig-2
6.3 Notes
1) Please be cautions not to give excessive static load or shock to switches.
2) Please be careful not to pile up P.W.B. after switches were soldered.
3) Preservation under high temperature and high humidity or corrosive gas should be avoided
especially. When you need to preserve for a long period, do not open the carton.
4) Avoid pressing the film portion of the product with sharp-edged object.
5) Cleaning
ï½¥If flux or solder is scattered on the surface of P.W.B when soldering, characteristics
of this product may be damaged.
ï½¥Cleaning after soldering is not allowed.When cleaning is required this switch should be
soldered after the cleaning.
6) Avoid the use of the switch under pushed ON condition is continued for a long time.
7) There is a possibility the flux from solder paste infiltrates into the body if plenty of
solder paste was applied by switch on the P.W.B.
So we recommend to use our proposed land design in order to prevent above problem.
Also please avoid putting additional land by the switch on the P.W.B.
