Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 2, fig. 2 is a structural diagram of an embodiment of a multi-camera module according to an embodiment of the present invention, where the multi-camera module includes:

In one embodiment, two side pads 221 may be disposed on two outer sides of the package substrate 22, for example, as shown in fig. 3, the side pads 221 are disposed on two opposite outer sides of the package substrate 22.
The side pads 221 are not limited to the half-hole structure shown in fig. 3, and may be pads with other shapes such as square, non-hollow, convex, etc., and the distribution structure of the pads may also be random, which is not limited in this application.
The solder ball may be the solder ball, and certainly, the solder ball may also be a metal of any other material, and the connection manner between the solder ball 222 and the side pad 221 is not limited in this application. For example, solder balls may be placed on the outer side of the side pads 221, or a metal plate may be attached to the side pads 221.
The peripheral size of the package substrate 22 is larger than the size of the bare chip 21, and the size difference between the package substrate and the bare chip does not exceed a preset threshold, which may be 2 mm. Generally, in order to reduce the volume of the whole multi-camera module, the size of the package substrate is slightly larger than the size of the bare chip 21, for example, the size of the bare chip 21 is 9 × 10mm (length × width), and the peripheral size of the package substrate 22 is 10 × 11mm (length × width).
The bare chip 21 is disposed on the package substrate 22, and the functional pins of the bare chip 21 are connected to the side pads 221 by a semiconductor wire bonding process to constitute a packaged chip.

After the double-camera module substrate finishes SMT welding of other devices, the packaged chip is pasted on the module substrate 113, and the welding pad of the packaged substrate 113 is burned by laser welding equipment, so that the packaged chip is welded and conducted with the welding pad of the module substrate 112. In order to ensure the welding reliability of the packaged chip, glue is sprayed on the periphery of the packaging bonding pad and the formed bonding pad protective layer 114 is solidified, so that the bonding pad is prevented from being easily broken and stripped due to the influence of external force. And finally, respectively carrying the base 115 and the lens 116 for the double-shooting module, and carrying out focusing detection to complete the manufacture of the double-shooting module.
