Packaging Board Visual Recognition Windows Jig-Free Soldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of soldering board terminals on a printed board requires a jig, which increases production costs and complexity, especially for applications with a small number of terminals, and reduces the density of the printed board due to the need for space around the jig for access to soldering portions.
Innovation Solution
A packaging board configuration that uses an insulation support member made of resin with tubular support portions and visual recognition windows, allowing board terminals to be inserted and soldered without a jig, reducing production costs and increasing terminal density by eliminating the need for a jig and allowing visual inspection of soldering portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a jig is used to hold board terminals for insertion, then the board terminals can be fixed for soldering, but the production cost and complexity increase
Solution Approach 1:
The patent extracts the essential function of the jig (holding and positioning board terminals) and transfers it to the insulation support member that remains on the printed board. The insulation support member integrates the positioning function directly into the board structure, eliminating the need for a separate removable jig while maintaining fixing reliability during soldering.
Solution Approach 2:
The insulation support member acts as an intermediary between the printed board and the board terminals. It provides the positioning and holding function that would otherwise require a jig, while being permanently integrated into the board structure. This intermediary solution eliminates the need for complex removable fixtures.
2Manufacturing precision
If a jig is used to hold board terminals, then the terminals can be positioned for soldering, but the board density decreases due to required access space
Solution Approach 1:
The patent merges the positioning function with the insulation support member that is already integrated into the printed board. By combining the support function and positioning function into a single integrated component, the design eliminates the need for additional space that would be required for a separate jig, thereby maintaining board density while ensuring precise terminal positioning.
Solution Approach 2:
The insulation support member provides positioning precision through its structural design in the vertical dimension (extending upward to hold terminals), rather than requiring horizontal space around the soldering area. This dimensional approach allows precise terminal positioning without reducing board area.
3Reliability
If a metal jig is used for board terminals, then the terminals can be supported, but the production cost increases
Solution Approach 1:
The patent replaces the expensive metal jig with a cost-effective insulation support member made from insulating materials that are already part of the printed board construction. This support member serves the same function as a metal jig but at lower cost, as it is integrated into the board rather than being a separate expensive fixture.
Solution Approach 2:
The insulation support member serves multiple functions: it provides electrical insulation, mechanical support for the printed board, and positioning/holding for the board terminals. By making the support member multi-functional, the design eliminates the need for separate expensive fixtures while maintaining support reliability.
4Ease of manufacture
If the insulation support member is made of resin, then the production cost decreases, but the visual inspection of soldering portions becomes difficult
Solution Approach 1:
The patent incorporates visual recognition windows with contrasting colors or transparent regions in the insulation support member. These visual features allow soldering portions to be easily inspected through the resin material, overcoming the opacity issue while maintaining the cost advantages of using resin instead of metal.
Solution Approach 2:
The insulation support member is segmented to include visual recognition windows that are distinct from the opaque resin portions. This segmentation allows specific areas (where soldering occurs) to be visually accessible while the rest of the support member maintains its insulating and structural functions.

AI summary
A packaging board of the type having board terminals soldered on a printed board and including an insulation support member made of a resin disposed on a printed board having tubular support portions configured to receive board terminals, visual recognition windows configured for visually recognizing soldering portions of the board terminals inserted into the printed board through the windows, and engaging portions that engage the board terminals and define insertion amounts of the board terminals.
