Describe circuit with reference to Fig. 7 to Figure 12 below and connect 133 manufacturing process and structure.As mentioned above, circuit connects 133 makes secondary circuit plate 135 be electrically connected with main circuit board 133c, and the communication path between imageing sensor 131 and the main circuit board 133c is provided.
Each coupling part 161 is formed at the edge of an end of main circuit board 133c and secondary circuit plate 135 respectively.As shown in Figure 8, each coupling part 161 comprises the array of a plurality of solder joints (solderingbase) 165.In addition, secondary circuit plate 135 comprises other solder joint 163 that is used for installation diagram image-position sensor 131.
Make main circuit board 133c and 135 alignment of secondary circuit plate, be straight line so that be formed at each solder joints 165 row who respectively connects 161 interior formation, many lead 133a are arranged on each solder joint 165, utilize each lead 133a, each solder joint 165 is connected by man-to-man pattern, carry out the welding 167 of solder joint 165 then.Except welding, the method that lead 133a is bonded to solder joint 165 respectively also can comprise method for ultrasound welding.According to ultra-sonic welded, the end points of lead 133a is arranged on each solder joint 165, then ultrasound wave is added on the end points of lead 133a, so that lead 133a is merged to solder joint 165.
As shown in figure 10, welding after 167, removing unnecessary lead, strenthening member 133b is being coated on the coupling part 161.Even when secondary circuit plate 135 moves with main circuit board 133c, strenthening member 133b can be used for also preventing that the welding portion of lead 133a from disconnecting or breaking-up.Here, strenthening member 133b can use hard epoxy and soft epoxy.In other words, on the coupling part 161 of the hard epoxy coated lead 133a of high rigidity after, in case the complete hardening of hard epoxy that is coated with, again or repeatedly the soft epoxy coated part of joining of soft in the surface and the lead 133a of hard epoxy.In this manner, even when the second framework 102b moves, can prevent that also stress from concentrating on the surperficial part of joining with lead 133a of hard epoxy.In order to insulate, to make lead 133a coated, and separately constitute these leads in a movable manner.
In the image stabilization operation of moving on traditional vertical direction at flexible print wiring, the load of flexible print wiring becomes bigger.Yet owing to the lead 133a of circuit connection 133 can separately move, thereby no matter the direction of motion of camera apparatus 103 how, can both guarantee to improve adjusted rate.
