U.FL Series

●Ultra Small Surface Mount Coaxial Connectors - 1.9mm or 2.3mm, 2.4mm Mated Height

Usage Precautions

1. Plugs

(1) Mating / unmating

(2) Pull forces on the cable

after connectors are

mated.

(3) Precautions

1) To disconnect connectors, insert the end portion of U.FL-LP-N-2 and U.FL-LP(V)-N-2 under the

connector flanges and pull off vertically, in the direction of

the connector mating axis.

2) To mate the connectors, the mating axes of both connectors

must be aligned and the connectors can be mated. The

"click" will confirm fully mated connection.Do not attempt to

insert on an extreme angle.

After the connectors are mating, do not apply a load to the cable in excess of the values indicated in the

diagram below.

Do NOT forcefully twist or deform wires.

(1) Recommended reflow

temperature profile

(3) Recommended metal

mask thickness

(4) Reflow cycles

0.1 to 0.12mm

2 times

(2) Recommended manual

soldering

2. Receptacles

q The temperature of the printed circuit

board surface temperature at the

points of contact with the terminals.

w Reflow soldering should be

performed at a printed circuit surface

temperature of 250°C max.

e In individual applications the actual

temperature may vary, depending on

the solder paste type, volume /

thickness and board size / thickness.

Consuly your solder paste and

equipment manufacturer for specific

recommendations.

(1) Operating environment

The connectors are not designed to operate in the following environments :

• Exposed to a excessive amounts of fine particles and dust

• Regions and places having a high density of sulfur dioxide, hydrogen sulfide, nitrogen dioxide or other corrosive

gasses.

• Environments having large rapid variations in temperature.

(2) Storage conditions -

Receptacle

Store in the Hirose Electric packaging.

Temperature : -10 to +40ç, Humidity : 85% max.

Use within 6 months of delivery.

Receptacles for which the storage period has elapsed must be tested for solderability to the PC board

mounting surface.
