specific Embodiment approach 1

[0015] Specific implementation mode 1. Combination Figure 1 to Figure 3 Describe this implementation mode, a method for connecting laminated circuit boards of a small satellite three-line array camera, the specific welding steps are:

[0016] (1) First, insert multiple connectors with a small number of single-row cores into the circuit board;

[0017] (2) Fix the socket on the upper part of the splicing connector to be welded with high-temperature-resistant standard-pitch pin tooling to ensure that the two-dimensional spacing is consistent and prevent the positioning from being affected by the deformation of the pins during the welding process;

[0018] (3) Then use high temperature resistant standard spacing protective cap tooling to fix the pins to ensure that the two-dimensional spacing of the pins is consistent;

[0019] (4) Use right-angle tooling to limit the overall verticality of the connector, and then perform manual welding. When welding, use a connector with a sma...

Abstract

A connection method for laminated circuit boards of a moonlet three-line-array camera relates to the technology of the laminated connection of a plurality of circuit boards, and particularly to an implement method that four sides of a circuit board are all provided with connectors, and single-row connectors with less cores are required to be used to make up multi-row connectors with more cores, and mainly aims to solve the problem that the conventional connection method is difficult to realize. The method conducts two-dimensional fixing for the socket part above the connectors through a contact pin tooling, conducts two dimensional fixing for the contact pin part below the connectors through a protective cover tooling, and meanwhile adopts a simple right-angled tooling to guarantee the verticality of the connectors; then the adjustment for relative positions of connectors of all layers of the circuit boards is conducted through a trial assembly after each single-row connector with less cores is subjected to single point welding; finally, the laminated connection between the plurality of circuit boards is finished.

Description

technical field [0001] The invention relates to a driving technology of a CCD, in particular to a method for realizing lamination connection of multi-load circuit boards of a small satellite. Background technique [0002] With the rise of small satellite applications, the size requirements for aerospace cameras are becoming more and more stringent. For the narrow size and space, the whole camera adopts the structure of multi-layer circuit board stacking. Due to the need for single-row, double-row and multi-pin connectors and the number is small, and the spacing of the circuit board is non-standard, in order to reduce the customization cost, all connectors are used such as single-row two-core and five-core cores Less connector splicing composition. The upper part of the single-row connector is the socket part, and the lower part is the pin part. When using a single-row connector with a small number of cores for splicing, the two-dimensional spacing between the socket and t...
