6. Prohibitions and precaution for handling
6.1 Reflow soldering condition
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)

Notes
Please be cautions not to give excessive static load or shock to switches.
Please be careful not to pile up P.W.B. after switches were soldered.
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) Cleaning
･If flux or solder is scattered on the surface of P.W.B when soldering, characteristics
of this product may be damaged.
･Cleaning after soldering is not allowed.When cleaning is required this switch should be
soldered after the cleaning.
5) Avoid the use of the switch under pushed ON condition is continued for a long time.
6) 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.

<Prohibitions and precaution for handling>
【Prohibited items on fire and smoking】
・Absolutely avoid use of a product beyond its rated range because doing so may cause a fire.
If misuse or abnormal use may result under conditions in which the product is used out of its
rated range,take proper measures such as current interruption using a protective circuit.
・The grade of nonflammability for resin used in product is "94HB," which is based on UL94
Standards (flammability test for plastic materials). Prohibit use in a location where a
spreading fire may be generated or prepare against a spreading fire.
【For use in equipment for which safety is requested】
・Although care is taken to ensure product quality,inferior characteristics,short circuits,
and open circuits are some problems that might be generated, To design an equipment which
places maximum emphasis on safety,review the effect of any single fault of a product
in advance and perform virtually fail-safe design to ensure maximum safety by:
･Preparing a protective circuit or a protective device to improve system safety,and equipment.
･Preparing a redundant circuit to improve system safety so that the single fault
of a product does not cause a dangerous situation.
【Attentions required for storage condition】
・When this product is to be stored in the following circumstances and conditions,it may
affect on the performance deteriorations and solderability etc.,avoid storing in the
following conditions.
(1)A place where the temperature is -10℃ max.,+40℃ min. and the humidity is 85% min.
(2)In the corrosive gas atmosphere.
(3)Long-term storage for 6 months min.
(4)A place where the product is exposed to direct sunlight.
・Store in packed condition so that the load stress is not applied.
・Please use this product as soon as possible,our recommendation is within 3 months and the
1imitation is 6 months.
・If any remainder left after packing is opened,store it with proper moistureproofing and
gasproofing,etc.,
