(4) Notes for mounting
Avoid mounting multiple connectors of this type on the same circuit board.
(If it is unavoidable to mount multiple connectors, take necessary measures for use, such as
separating the circuit board between the connectors.)
When the connector is mounted on an FPC, insufficient stiffness may lead to land pattern
separation or solder separation. It is recommended that the FPC should be lined with a
stiffening film.
(5) Precautions
1. Do not mate or unmate a connector with an excessive prying force. It may cause a failure
of the connector.
2. The connector may become disconnected if it is dropped, or extreme stress is applied to
the FPC. To prevent this from happening, fix the connector in place by holding it with an
added portion of the case or some type of cushioning material.

1. The temperatures indicated are the surface temperatures on the printed circuit board at
the points of contact with the terminals.
2. Reflow soldering should be performed at a peak temperature of 250°C or less at the
surface of the printed circuit board.
3. The temperature profile varies depending on conditions such as the size of the printed
circuit board, the solder paste type, and solder thickness.

(1) Operating environment
This product was designed under the assumption that it would be used in a normal operating
environment.
Use of this connector under adverse environmental conditions may lead to discoloration or other
kinds of degradation. Use of the connector in regions having exposure to excessive amounts of
fine particles and dust, high densities of sulfur dioxide, hydrogen sulfide, nitrogen dioxide or other
corrosive gasses (e.g., exhaust gas from automobiles or factories), is not advised
Environments having a large difference in temperature, such as a place near a heater.
(2) Storage conditions
Store the product in Hirose Electric's packaging or similar packaging conditions.
Temperature: -10 to +40°C, humidity: 85% or less (recommended storage conditions)
Use the product within six months from delivery.
Products for which the storage period has expired must be tested for solderability before the use.
