Problems solved by technology
[0003] There are many technical difficulties in the existing alignment installation, such as (1) there is a slight skew of individual pins during the CCD incoming material or splicing process. Since the pins of multiple CCDs spliced have hundreds or thousands of points, as long as If one of the pins is inaccurate, the PCB cannot be installed in place; (2) The PCB to be installed is welded with many electronic components such as resistors, capacitors, and devices. During the docking process with the CCD pins, the PCB pad hole It must be strictly aligned with the CCD pins to complete the installation
Furthermore, the efficiency of the existing alignment installation is low

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] As mentioned in the background technology, there are many technical difficulties in the existing alignment installation, such as (1) there are slight skews in individual pins during the CCD incoming material or splicing process, because the pins of multiple CCDs spliced have hundreds of points Or thousands of points, as long as there is one pin inaccurate, the PCB cannot be installed in place; (2) The PCB to be installed is welded with many electronic ...

The invention discloses an auxiliary installation template and an alignment installation method. The auxiliary installation template is applied to the alignment installation of pins of multiple spliced CCDs and pad holes of a circuit board. The auxiliary installation film plate includes: an installation substrate ; A plurality of mounting holes arranged on the mounting substrate, the number of the mounting holes is the same as the number of pins of the multiple CCDs, and the arrangement of the mounting holes on the mounting substrate is the same as that of the The arrangement of the pad holes on the circuit board is the same. In the alignment installation process of the pins of the spliced multi-chip CCDs and the pad holes of the circuit board, firstly, the mounting holes of the auxiliary installation template are aligned with the pins of the spliced multi-chip CCDs to improve the splicing. The deviation of the pins of the multi-chip CCD; and then quickly align the pins of the adjusted spliced multi-chip CCDs with the pad holes of the circuit board to ensure the pins of the spliced multi-chip CCDs and the circuit board. The alignment mounting efficiency of the pad hole is high.
Description
technical field [0001] The invention relates to the technical field of assembly of electronic products, and more specifically relates to an auxiliary installation template and an alignment installation method. Background technique [0002] At present, CCD (Charge-coupled Device, charge-coupled device) has been widely used in the field of aviation and aerospace optical remote sensors. With the development of satellite remote sensing application technology and actual needs, wide-field-of-view and high-resolution cameras have become a development trend. When the total length of the pixels of a single CCD cannot meet the coverage width of the field of view of the camera imaging, it is necessary to connect multiple CCDs into a wide field of view detector, which is called CCD splicing. CCD splicing is a special technology developed by CCD cameras, and mechanical splicing is more commonly used. Such as figure 1 A schematic diagram of a splicing structure of 5 CCDs is shown. The m...
