Note 1 : The temperature is the surface temperature of the PCB in the vicinity of the connector
lead part.
Note 2 : When you use nitrogen reflow, please mount the product with the oxygen concentration
at a minimum of 1,000 [ppm].
Please contact us if the concentration is below 1,000 [ppm].

5. Cleaning
Soldering iron temperature : 340 ± 10°C,
Soldering time : within 3 seconds
Thickness : 0.1mm
Aperture ratio : 100% on the DS side ; 80% on the DP side
A maximum of 0.02mm at the center part of the connector based on both ends of the connector.
Not recommended. If you clean this product, please evaluate the performance before using it.
(Cleaning may cause a change in the mating/unmating property and its resistance to
environment)
Care should be taken that mating/unmating operation when the product is not mounted on the
PCB could cause damage or deformation, etc. of the contact.
Avoid supporting the PCB only by connectors, and support it by other means than connectors.
Care should be taken that excessive prying mating/unmating could cause damage.
During hand soldering, do not apply flux which will cause flux oozing on connector.
This product may differ in hue due to production lot variability, but it doesn’t have any
influence on the performance.
Please refer to the next page for the precautions for mating/unmating.
Considering the possibility of disengagement due to the counterforce caused by the drop, impact
and routing of FPC, fix the mated state by the use of housings and cushion materials, etc.
Caution! Do not use the connector in non-recommended conditions (i.e., rated current, rated
voltage, PCB design and operating environment, etc.). Such usage could lead to material
outgassing, ignition, or short-circuit, etc.
Refer to the specifications and the guidelines for board pattern dimensions, board cautions,
and connector treatment.
Pleasae contact Hirose if using the connector under conditions other than those described in
the specifications and the guidelines is being considered.
