INSTRUCTIONS OF THE INVENTION · TECHNICAL FIELD OF THE INVENTION [0003] An electrical connector is disclosed, particularly in relation to a flexible connector that is bonded to a circuit board using a surface-exposed technique. [Prior Art] For the purchase of more ==: laborious purchase of the most important = two S In response to this situation, the electronic functional components are as much as possible to mold one or several integrated circuit (IC chip) attached to a =. More time, the circuit of the single PCB is an electronic device, which usually needs to be combined with the audio or video reading mechanism of the biting machine or the audio to read the sub-CD or DVD film. This is the case. When connected to another PCB, or when one (10) and machine ίίίί, the lion electrical connections 11 are indispensable components. Appropriately, the 3 electrical connectors can shorten the maintenance time required for the assembly, or the components can be arranged more closely, and the volume is significantly reduced. Also, the edge is provided for the expandability of the electrical device. ί ί fί ϊΐ—Multiple signals between the PCB and the other PCB are connected at the same time. ίΐρΐί iif line 'especially the height of the two PCBs is not equal or two ΐ ϊ ί ί ί ί ί 又 又 又 又 又 又 又 又 又 又 又 又line. The meeting is not _5 whether it is the general cable 5 or the soft cable is required - set to ili test 1), and both ends need to have the socket f0 (socket) required to connect the socket 10 (pin). The soft cable is more than the general cable 1248241 ϊΐ one ί =: 2 ' 'surface 峨 is the two rows of PCB reserved for each end ^ 图 mouth 2, it requires the foot 35 placed on the terminal 4 〇 Whoever - ^ only needs to connect the pins of the connector 30.

The cable 5 and then ^^^ two TM connected to the user can be easily disassembled or bounced out of the LY 2 machine maple arm capacity support 45 for automation = plastic to reach the scales 45 degrees it Γ 4 the invention Flexible surface 4 connection: 3⁄4 adapter. The use of large angle phases solves the shortcomings of traditional connectors. SUMMARY OF THE INVENTION The following two methods of manufacturing a connector include at least a facet ίί:·ϊίί=processing a metal strip to form a flat middle, a second and a middle segment, and a medium to thinner middle segment It can increase the bending property, and the welding 1244821 pin position, the spacing is matched with the terminal distance of the printed circuit board - the flexible dielectric vine middle section and part of the second section, and pre = 妾; the electro-membrane selectable polyimide film Pressing _ to pressurize and heat to make the ^^ pin _" shaft support. The contraction of the press machine is ~195t. Then, the welding pin is transferred to the core. Money, then add the The planar connector is formed to form a shape, and the middle portion of the hysteresis is higher than the second segment and the soldering pin. The conversion facilitates the surface lining with the printed circuit board to prevent the camera from being taken up. [Embodiment] The inflexibility of the surface-adhesive connector is mainly due to the fact that the support portion is made of a plastic material, and the present invention is replaced by a slidable material, so that the connector becomes flexible. The following content will explain the flexibility in detail. The manufacturing method and structure of the silk surface connection H. The flexible surface-adhesive connector of the invention adopts a thermocompression bonding method to form a flexible dielectric material into a support portion. The surname of the press-fitted cymbal is shown in FIG. 3, and the press machine is lowered from the lower side. On the other hand, it contains heat-insulating asbestos, heating plate 115, / mouthpiece 120, burnt iron plate; [25, fiberglass sheet 130, enamel rubber sheet 130, fluorocarbon resistant 〇 14 〇. The upper 包含 contains asbestos 110 from top to bottom The heating plate 115, the jig 120, the 矽 rubber sheet 135, and the FR-resistant 140.

The pin talk (ρίΝ) 150 can be cut into 150a 150b, 15〇c, 150b, 150a. The width of the two sections of the Chinese ϋ ΐ 约 is about the same, but less than the second Μ:: The middle part is finer, which makes the bending easier. The first itching is the splicing pin 150a It is to match the width of the terminal of the printed circuit board to provide a larger surface strength. For the deformation, please refer to Fig. 4. In the medium 22, the end of each soldering pin 15Ga is about 〇·2_, and the spacing of the bit 150a depends on the distance of the PCB terminal. For example, it can be connected!: 〇·7mm or lmm. The welding pin 150a is connected to the rain 160. The transporting film 6 is provided with a positioning hole 17〇 formed in an embodiment thereof, and the punching of the connector is the connection of the fuser machine. The positioning hole 170 can be Simultaneously with the punching of the "Winter", or providing a metal tab including the positioning hole 170, the stitching of the stitch 150 is performed. Next, the flexible dielectric film or the highly flexible thermosetting glue 155 is cut, and the polyimide film (polyimide; ?1) or the apton produced by DuPont of the United States is applied to the middle of the stitch 15 〇c and part of the second The paragraph is still awkward The hot material is about dl3 (Tc temporarily _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In a preferred embodiment, the thermocompression conditions are about 3 〇 to 45 kg / 1248241, which will be: two; with an electric bearing with a wheat package n°, the vacuum is used to suck the finished product against the static invention. Advantages: The pgfH property can be connected with a table, and the angle can be folded, so that the degree can be fixed, because m' is: ϊϊ, and then the connector is bent into a pre-existing second, which is only a preferred embodiment of the present invention. The scope of the patent application of the present invention is not limited to the scope of the patent application of the present invention, which is not limited by the scope of the invention. The preferred embodiment of the invention will be explained in more detail in the following description with the following figures: Figure 1 is a schematic view of the cable, the socket needs to be matched with the pins. Figure 2 shows the traditional surface of the connection Because the support part is inflexible plastic, the needle connecting the two PCBs It is necessary to pre-angle the corners and lose the convenience of use. Figure 3 shows a front view of a press designed in accordance with the method of the present invention. Figure 4A shows a planar surface dead connector formed in accordance with the method of the present invention.
