Problems solved by technology
Therefore, when welding is performed manually by hand as in the past, there is a problem that it is difficult to accurately connect the electrode 501 of the microphone and the electrode terminal 511 of the FPCB.
[0008] In addition, due to the miniaturization of the FPCB 510, it is difficult to hold the FPCB 510, so there is a high risk of loss, and there is a problem that it is difficult to accurately position the electrode terminal 511 of the FPCB 510 on the electrode 501 of the microphone.

Embodiment Construction
[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0025]
[0026] FIG. 2 is a sequence diagram showing a mounting method of the present invention, and FIG. 3 is a diagram showing an FPCB partially connected to a mother board.
[0027] Referring to FIG. 2 , the method for installing a microphone to an FPCB according to the present invention is as follows: First, a plurality of FPCBs 20 are formed on the motherboard 10 in a certain arrangement. At this time, as shown in FIG. 3 , a plurality of FPCBs 20 are partially connected to the motherboard 10 through bridges 11 . With such a structure, when the microphone is mounted on the FPCB, the FPCB 20 moves together with the mother board 10 as a whole, so there is no risk of losing the FPCB 20 even if its size is small.
[0028] Referring to FIG. 3 , the FPCB 20 is composed of a mounting portion 21 on which a microphone is mounted, and an ex...

A mounting method for mounting a microphone onto a flexible printed circuit board is provided in the present invention, it is characterized in that comprising: first step, preparing mother board according to the mode of leading a plurality of FPCBs to separately locally connect with mother board and process arrangement, there are an electrode terminal connecting with the microphone, a connecting terminal connecting with the main board and a circuit pattern for electric connecting the electrode terminal and the connecting terminal forming on the FPCBs; second step, coating soldering medium on the electrode terminal of the FPCB; third step, placing the microphone on the electrode terminal coated soldering medium of the FPCB; forth step, mounting the microphone onto the FPCB by surface mounting technique; and fifth step, relieving the locally connecting, separating out FPCB mounted microphone from mother board. By the structure, miniaturization microphone and FPCB lost danger can reduce,and can realize automation, therefore comparing with the prior art by hand-operated work to mount, it can promote operation efficiency.
Description
technical field [0001] The invention relates to an installation method for installing a microphone arranged inside a mobile phone or a portable multimedia electronic device on a flexible printed circuit board. More specifically, the present invention relates to a mounting method for mass mounting miniaturized microphones on a flexible printed circuit board through an automated process. Background technique [0002] In recent years, multimedia electronic devices that are often accessible around, such as MP3 (Moving Picture Experts Group Layer 3), video cameras (Camcorder), mobile phones (Mobile) and other electronic devices generally provide the function of transmitting or recording the sound generated around. Especially for multimedia electronic equipment that has the trend of miniaturization, thinning, and high performance, an important reason for realizing this type of recording function is that because of its miniaturization, it constitutes a microphone that can be instal...
