Abstract
The utility model relates to a connecting structure of flexible printed circuit and connector, which comprises a flexible printed circuit connected with a gold finger pad, a connector provided with gold fingers, and a high-temperature gummed paper stuck on the flexible printed circuit. A window making the gold finger pad coming out is arranged on the high-temperature gummed paper. The gold finger is jointed on the gold finger pad. Wherein, the gold finger pad spreads to be a conducting tin piece in the direction far away from the connector. The conducting tin piece is fixed in the flexible printed circuit and arranged in the window. In the jointing process, the excrescent soldering tin between the gold finger pad on the flexible printed circuit and the gold finger on the connector will flow out along the conducting tin piece, and form tin sweats on the conducting tin piece. So bridge can be avoided among the gold finger pads or among the gold fingers on the connector, and rosin joint or cold solder can be avoided between the gold finger pad on the flexible printed circuit and the gold fingers on the connector.
Description
Technical field
The utility model relates to the syndeton of a kind of wiring board and connector, especially relates to the syndeton of a kind of flexible circuit board and connector.
Background technology
The golden finger pad of flexible print circuit board (hereinafter to be referred as FPC) and the golden finger of connector adopt tin-welding process to connect as one, from two aspect assessment welding qualities, the one, mechanical performance, be FPC with connector between be connected mechanical strength, the pulling force that bears between FPC and connector size and peel off intensity, FPC is that the carrier of connector must bear corresponding pulling force and peels off that intensity is unlikely to come off, to guarantee that weld can not come off when vibrations taking place and fall phenomenon; The 2nd, electric property, be the electrical performance indexes between FPC and the connector, the distributed constant that resistance and inductance, electric capacity etc. form, resistance are the important indicators of weighing electrical property, with scolder and welding procedure direct relation is arranged, directly influence the function of entire circuit and the quality of performance.
At present, the syndeton of flexible circuit board and connector, comprise the FPC substrate, be located at golden finger pad, connector on the FPC substrate, stick on the high tempreture tape (PI TAPE) on the FPC substrate, offer on the high tempreture tape (PI TAPE) make the golden finger pad expose with connector on the PI of golden finger welding window, be located at the length basically identical of the length of the golden finger pad on the FPC substrate and the golden finger on the connector and weld together, thereby connector is fixed on the FPC substrate.Along with development of electronic technology, the connector of multifrequency pin (PIN pin) more and more is applied in the electronic product, and the centre-to-centre spacing between the golden finger is very little on centre-to-centre spacing (PITCH) between last adjacent two the golden finger pads of FPC and the connector, in welding process, the golden finger pad on the FPC is inwardly or lateral flow possibly for unnecessary scolding tin, because the gap between the golden finger pad on connector golden finger and the FPC is very little, unnecessary tin is crushed after will forming tin sweat(ing), after the tin that is crushed in the horizontal links to each other, can be at the company's of formation tin between the adjacent golden finger pad or between the adjacent golden finger, and rosin joint also very easily appears between the golden finger on golden finger pad and the connector, the situation of dry joint, FPC and connector are difficult to form effective bridge joint, have had a strong impact on the welding quality of product.Because after FPC and the connector bridge joint, connector male seat and female seat are regular separates and combines, the connecting portion of FPC and connector must bear corresponding pulling force and peel off intensity, be easy on the FPC golden finger pad band fall, had a strong impact on the mechanical performance of welding quality.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly welds accurately firmly, can bear bigger pulling force and peel off the flexible circuit board of intensity and the syndeton of connector.
For solving the problems of the technologies described above, the syndeton of a kind of flexible circuit board of the utility model and connector, comprise the flexible circuit board that is provided with the golden finger pad, be provided with the connector of golden finger and stick on high tempreture tape on this flexible circuit board, offer on this high tempreture tape and make windowing that the golden finger pad exposes, this golden finger is welded on this golden finger pad, wherein, described golden finger pad extends to form to the direction away from described connector and leads the tin sheet, and this is led the tin sheet and is fixed on described flexible circuit board and is positioned at described windowing.
As a kind of improvement of the present utility model, wherein, the described tin sheet of leading extends to form reinforced sheet to the direction away from described connector, and this reinforced sheet is fixed on described flexible circuit board and between described flexible circuit board and described high tempreture tape.
As a kind of improvement of the present utility model, wherein, the described tin sheet of leading extends to form reinforced sheet to the direction away from described connector, and this reinforced sheet is fixed on described flexible circuit board and between described flexible circuit board and described high tempreture tape; This reinforced sheet edge is 0.3 millimeter to 0.9 millimeter away from the length of the direction of described connector.
As further improvement of the utility model, wherein, the described tin sheet of leading is 0.4 millimeter to 0.8 millimeter along the length away from the direction of described connector.
The utility model compared with prior art, the syndeton of a kind of flexible circuit board of the utility model and connector, because extending to form to the direction away from described connector, the golden finger pad on the flexible circuit board leads the tin sheet, in welding process, unnecessary scolding tin will be along leading that the tin sheet outwards flows and forming tin sweat(ing) leading on the tin sheet between the golden finger on golden finger pad on the flexible circuit board and the connector, play the effect of depositing unnecessary tin, thereby both can avoid between the golden finger pad or take place to have connected tin on the connector between the golden finger, on golden finger pad on the flexible circuit board and the connector rosin joint can not appear between the golden finger, dry joint, also can realize effective bridge joint of flexible circuit board and connector, make be electrically connected more reliable; By extending to form reinforced sheet owing to lead the tin sheet to direction again away from described connector, this reinforced sheet is fixed on described flexible circuit board and between described flexible circuit board and described high tempreture tape, male seat that a kind of flexible circuit board of the utility model and the syndeton of connector effectively bear connector and female seat are often separated bring bigger pulling force with combining and peel off intensity, thereby improve the useful life of product.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is that the master of the syndeton of a kind of flexible circuit board of the utility model and connector looks the broken section structural representation.
