(3) in the process of welding, because of influences such as staff's experience number or environmental factors, the weld 15 that flexible circuit board 10 and transmission line are 13, the situation of empty weldering (missing solder) takes place sometimes, causing flexible circuit board 10 positively to form with transmission line 13 is electrically connected, cause this flexible circuit board 10 can't operate as normal, cause the fraction defective of product high; And

(4) when the weld 15 of staff to 13 of flexible circuit board 10 and transmission lines; when carrying out the closed routine of PUR; usually can inject PUR (shown in the arrow of Figure 1A) by the side of this weld 15; at this moment; because the weld 15 that flexible circuit board 10 and transmission line are 13 is comparatively tiny; therefore; be subjected under the impulse force influence that PUR is injected into; the situation of fracture then takes place easily; cause the flexible circuit board 10 through closed routine can't be applied on the product, make the dealer suffer loss in the production.

In sum as can be known, the connected mode of existing flexible circuit board and transmission line, on using, many disappearances are arranged still, especially pursue in the process of size miniaturization at product, it is serious relatively that aforementioned disappearance can become especially, therefore, how to design a kind of connected mode of innovation, effectively solving foregoing problems, become each electronic product dealer, manufacturer at present, desire most ardently an important topic of reaching.
