01. Introduction
Our F4S series consists of ultra-small connectors with a terminal pitch of 0.4 mm, a
stacking height of 1.00 mm, and a shorthand width of 3.6 mm. This connector is
designed for board-to-FPC connections that require a more space-saving connector than
our F4 Series.
For this purpose, the size and thickness of the molded part has been further reduced.
Select the types best suited to the conditions of use. Read this document before
designing a product and starting production.

02. Precautions for product design
02-1. Considerations in mechanical design
1) Position of the connector on a board
(1) When using board to board connectors, a pair of board shall NOT be connected
with multiple connectors. Otherwise, misaligned connector positions may cause
mating failure or product breakage.
Panasonic corporation does not guarantee the failures caused by using the
multiple connectors.
(2)Rigid boards tend to warp in a direction perpendicular to the rolling direction
during the production process. Poor soldering may occur depending on the
warping direction. Make sure to place the connector in a direction which reduces
warpage.
This space causes poor
soldering.
Tends to warp in the
manufacturing (lateral) direction.
Poor soldering can be reduced by
designing a mounting pattern to place
the connector in a lateral direction.

2) Position of the connector in the mounting process
Design multi-pin connector layouts that do not require a swinging movement
during pickup and mounting.
In many cases, deviation of the connector mounting position is caused by the
inertia of the swinging movement of the mounter. A layout that does not require
swinging is thus required.
●Example of a connector layout requiring a swinging movement in the mounting process
3) Prevention of problems during use
(1)The F4S connectors have a simple locking structure, but make sure to
consider preventive measures against the detachment of mated connectors
during practical use.
- Make sure to eliminate any gaps between the casing and board.
- We recommend that the holding force is set greater than the insertion force of
the connector.
- Select an appropriate cushioning material with a suitable shape and dimensions,
and hold down the connector at the center. (If the holding position is off the
center, it may cause detachment of mated connectors.)
