Page 3: Introduction
Operation manual for Narrow-pitch connectors F4S 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. -

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. - Page 5 ○ Motherboard No rotation inertia Connector 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. Cushioning material Casing Reinforcing plate...

- Page 7 Operation manual for Narrow-pitch connectors F4S 02-2. Precautions for board design 1) Circuit design (1)When designing the terminal foot pattern, check the latest specifications and examine the recommended foot pattern and dimensions of the metal mask opening. The current recommendations are indicated on pages...
- Page 8 Operation manual for Narrow-pitch connectors F4S (4)Precautions when providing a pattern and through-hole inside the prohibited area As shown below, the header’s post extends down to the bottomface of the molded part, and the post extends horizontally beyond the molded part becomes the terminal.
- Page 9 Operation manual for Narrow-pitch connectors F4S (6)Pay attention to the following points when providing a through hole by extending the foot pattern. If a through-hole is created simply by extending the foot pattern by the same width, solder is absorbed into the through-hole during the reflow process, which may cause defective or poor soldering of the terminals.
- Page 10 Operation manual for Narrow-pitch connectors F4S 2) FPC board design (1)Positions of connectors on the FPC The FPC board is made by laminating a polyimide layer, copper foil, and adhesive layers. Since each material has slightly different heat-shrinkable properties, warpage may occur typically due the reflow heat in the following cases. This may cause poor soldering.
- Page 11 Operation manual for Narrow-pitch connectors F4S (2)FPC board specifications Control the thicknesses of the coverlay and adhesive to prevent poor soldering. There is a clearance of about 0.05 mm between the bottom surface of the terminal and the molded part.
- Page 12 Operation manual for Narrow-pitch connectors F4S 3) Reinforcing plate design We recommend the use of a reinforcing plate with appropriate thickness and rigidity to prevent solder peeling and pattern peeling when unmating the connector, and to guard against board warpage during the reflow process.
- Page 13 Operation manual for Narrow-pitch connectors F4S Metal Mask Design Since this connector is designed with an ultra low-profile, pay attention to the following precautions for reflow soldering. (1)In addition to the amount of applied solder, the reflow-soldering environment and temperature profile affect the finish quality after reflow soldering. Make sure to adjust the amount of solder applied after checking the finish quality in a test run.

Example of machine vacuum pressure setting: 480–520 mmHg ■ Picking up the socket Socket (1)The suction area on the socket is 0.8 mm in the shorter direction. ● Example of the nozzle (Source: Panasonic Factory) (Unit:mm) Number of contacts 20-30 40-50 ●... - Page 17 Operation manual for Narrow-pitch connectors F4S ■ Picking up the header (1)The suction area on the header is 0.8 mm in the shorter direction. If it is difficult to reliably insert the nozzle to the connector bottom face of 0.8 mm widthwise, the header can be picked up by converting the entire top face of the connector as shown below.
- Page 18 Operation manual for Narrow-pitch connectors F4S 03-2. Precautions for reflow soldering (1)Measure the temperature profile at the mounted connector position, and make sure that it conforms to the recommended profile. (2)When the molded part of connector melts or becomes deformed during the reflow process, the heating temperature may be too high, or the connector may be affected by a nearby electronic component with high heat capacity.
- Page 19 Operation manual for Narrow-pitch connectors F4S 03-3. Precautions for manual soldering and solder rework The size of this connector has been reduced in order to achieve a narrow pitch and save space. Therefore, take great care when carrying out manual soldering or rework.
- Page 20 Operation manual for Narrow-pitch connectors F4S 03-4. Detailed precautions for solder rework (1)Flux-applying tool To prevent solder creeping to a contact section, we recommend the use of a brush pen that can apply an appropriate amount of flux. (e.g., BON-102F, Japan Bonkote)
- Page 21 Operation manual for Narrow-pitch connectors F4S 03-5. Detailed precautions for manual soldering (1)General precautions - When applying flux, apply it thinly on each foot pattern using a brush pen as shown on the previous page. (Place the connector at a predetermined position after applying flux.)

Page 22: Precautions For Mating And Unmating
Operation manual for Narrow-pitch connectors F4S 04. Precautions for mating and unmating 04-1. Precautions for mating This connector features a compact and thin design. Although it is designed to be easily handled, follow the rules for mating below to avoid damage to the molded part and buckling or deformation of the contact. - Page 23 Operation manual for Narrow-pitch connectors F4S 04-2. Precautions for connector unmating (1)Hold the reinforcing plate at unmating the connector. (2)Lift straight up to unmate. (3)If the method of unmating described above is not feasible due to a lack of space around the connector, try the following methods.
- Page 24 Operation manual for Narrow-pitch connectors F4S ■ Proposal on unmating jig Tolerance (unless otherwise specified): ±0.1 Detailed drawing of the unmating jig edge ■ How to unmate (1)Hook the unmating jig onto one of the shorter side faces of the connector.
