Page 3: Introduction
Operation manual for Narrow-pitch connectors A35US 01. Introduction Our Advanced series A35US consists of ultra-small connectors with a terminal pitch of 0.35 mm, a stacking height of 0.6mm, and a shorthand width of 2.2 mm. This connector is designed for board-to-FPC connections that require a more space-saving connector than our A35S Series. -

Operation manual for Narrow-pitch connectors A35US 02. Precautions for product design 02-1. Considerations in mechanical design 1) Position of the connector on a board 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. - Page 5 Operation manual for Narrow-pitch connectors A35US 3) Prevention of problems during use (1)The 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 6 Operation manual for Narrow-pitch connectors A35US (3)To facilitate the mating of connectors, we recommend that you pay attention to the following points when designing the motherboard. - Provide a reference mark. - Design a layout that allows easy-checking of the connector mating condition.
- Page 7 Operation manual for Narrow-pitch connectors A35US 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 13 and 14.
- Page 8 Operation manual for Narrow-pitch connectors A35US (4)Pay attention to the following point as a pattern peeling preventive measure when removing the connector. - Make the foot pattern length longer than the coverlay opening. In general, at least 0.3 mm. (5)Foot pattern dimensions indicated in the drawings are intended to achieve the minimum area on the premise that the reflow-soldering process is used.
- Page 9 Operation manual for Narrow-pitch connectors A35US (7)Resist between pins When it is needed to provide resist between the pins, there is a way to adopt the overresist method as below. （If the resist is out of alignment, the pattern width 0.20mm would not change.)
- Page 10 Operation manual for Narrow-pitch connectors A35US 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 A35US (2)FPC board specifications Control the thicknesses of the coverlay and adhesive to prevent poor soldering. This connector has no stand-off. Therefore, minimize the thickness of the coverlay, etc. so as to prevent the occurrence of poor soldering.
- Page 12 Operation manual for Narrow-pitch connectors A35US 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 A35US 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.

- Page 20 Operation manual for Narrow-pitch connectors A35US 03-3. 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 22 Operation manual for Narrow-pitch connectors A35US 03-5. 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 23 Operation manual for Narrow-pitch connectors A35US 03-6. 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 24 Operation manual for Narrow-pitch connectors A35US 03-7. Flux cleaning method of PC board There is no need to clean this product. If cleaning, pay attention to the following points to prevent the negative effect to the product (1)In order to keep the solvent purity and to enhance cleaning, prepare equipments such as boil, ultrasonic cleaning with cold solvent and vapor washing.

Operation manual for Narrow-pitch connectors A35US 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 27 Operation manual for Narrow-pitch connectors A35US 04-2. Precautions for connector unmating (1)Hold the reinforcing plate at unmating the connector. (2)Lift straight up to unmate. Lift up (3)If the method of unmating described above is not feasible due to a lack of space around the connector, please lift around one of the shorter sides of the connector to unmate it.
