Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing insertion mounting type connectors face soldering defects and temperature management issues when using a reflow system with a position aligning plate covering the circuit board, as hot air is blocked, preventing efficient heat distribution to soldering parts.
Innovation Solution
Incorporating vent holes in the position aligning plate and/or the connector housing to allow hot air to reach the soldering parts, ensuring effective heat distribution and preventing soldering defects, even when the circuit board is covered by the position aligning plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a position aligning plate is used to prevent misalignment of foot portions with through holes, then positioning accuracy is improved, but hot air cannot reach soldering parts easily causing soldering defects
Solution Approach 1:
The position aligning plate is designed with through-holes that allow hot air to pass through. These holes enable thermal energy to reach the soldering parts while the plate maintains its positioning function, resolving the contradiction between positioning accuracy and soldering quality.
Solution Approach 2:
The through-holes in the position aligning plate act as intermediaries that allow hot air to penetrate through the plate structure. This mediator approach enables heat transfer without compromising the plate's positioning function, simultaneously achieving both positioning accuracy and reliable soldering.
2Manufacturing precision
If a position aligning plate covers the vicinity of the circuit board, then positioning accuracy is improved, but temperature management becomes difficult
Solution Approach 1:
The position aligning plate incorporates through-holes that allow hot air to pass through, enabling temperature management despite the plate covering the circuit board vicinity. This porous structure maintains positioning accuracy while facilitating thermal access.
Solution Approach 2:
The position aligning plate is segmented with multiple through-holes distributed across its structure. This segmentation allows hot air to reach multiple soldering points simultaneously while the plate maintains its overall positioning function, enabling effective temperature management.
3Manufacturing precision
If the position aligning plate blocks hot air, then positioning accuracy is maintained, but heating efficiency decreases
Solution Approach 1:
The position aligning plate is designed as a porous structure with through-holes that allow hot air to pass through. This maintains positioning accuracy while significantly improving heating efficiency by enabling direct thermal access to soldering parts.
Solution Approach 2:
The through-holes serve as intermediaries that facilitate heat transfer through the position aligning plate. This mediator structure allows the plate to simultaneously maintain positioning accuracy and enable efficient heating by allowing hot air penetration.

AI summary
A connector includes a connector housing, a plurality of terminals including foot portions extending to the outside of the connector housing, and a position aligning plate including a plurality of terminal insertion holes, the foot portions of the terminals being configured to be inserted into the terminal insertion holes so that the foot portions align with corresponding through holes of a circuit board. The foot portions of the terminals are configured to be soldered with the circuit board by a reflow system using hot air as a hearing source. A vent hole is provided in the position aligning plate to introduce the hot air to soldering parts through the vent hole.
