In this embodiment, the sensor module 106 is achieved through CSP manufacturing technology. Therefore, the sensor module 106 comprises a sensor chip 122, a flexible printed circuit board (FPCB) 124, an adhesive 126, and a stainless steel sheet 128. The method of assembling the sensor module 106 is well known in the art and is thus omitted here for simplicity. Please note that the housing 112 and the base part 114 are hollow. To manufacture the camera module 100, the holder 104 must be made first through injection molding technology utilizing a mold, and then the lens set 102 is inserted into and fixed in the housing 112 through the base part 114. The sensor module 106 is assembled and a distance between the holder 104 and the sensor module 106 is then calibrated. Finally, an adhesive material is injected between the base part 114 of the holder 104 and the sensor module 106 to maintain the distance between the holder 104 and the sensor module 106.

Similar to the first embodiment, to manufacture the camera module 200, the holder 204 must be made first through injection molding technology utilizing a mold, and the lens set 202 then inserted into the housing 212 through the base part 214. The sensor module 206 is assembled and a distance between the holder 204 and the sensor module 206 is then calibrated. Finally, an adhesive material is injected between the holder 204 and the assembled sensor module 206 to maintain the distance between the holder 204 and the sensor module 206. Please refer to
Because the housing of the holder and the base part are integral in some embodiments of the present invention, the prior art assembly step of screwing the lens barrel into the holder can be saved, therefore avoiding a deviated light axis caused by an improper force applied on the lens barrel, and further avoiding dropped particles caused by friction between the lens barrel and the holder. Moreover, the housing and the base part are integral, so the assembling inaccuracy can be avoided, the strength of the housing and the base part as a whole can be enhanced, and the production costs can be decreased.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
