Probe Card Electronic Part Mounting in Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Probe cards face challenges in effectively mounting electronic parts due to limited space, especially as the number of power supplies increases, making it difficult to efficiently place relay switches and other components.
Innovation Solution
The design incorporates a probe card with a wiring board, a connector, and a holder that uses through holes or recesses to create mounting spaces on the wiring board, allowing for efficient placement of electronic parts like relay switches and capacitors, even when the height exceeds that of the probes, by utilizing the space between connection pins and capacitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic parts are mounted on the probe card surface where probes are provided, then power supply management capability is improved, but the height of electronic parts is limited by the probe height
Solution Approach 1:
The patent transitions from two-dimensional surface mounting to three-dimensional space utilization by mounting electronic parts on the lower surface of the connection structure, which is opposite to the probe surface. This dimensional change allows electronic parts with greater height than probes to be mounted without spatial conflict, resolving the height limitation while maintaining power supply management capability.
2Adaptability or versatility
If the number of relay switches is increased to match the increase in power supplies, then power supply management capability is improved, but the space for placing electronic parts is reduced
Solution Approach 1:
By utilizing the lower surface of the connection structure as a mounting area, the patent creates additional spatial capacity that does not conflict with probe placement. This allows the number of relay switches to be increased proportionally with power supplies while maintaining adequate space for all electronic parts through vertical and lateral space optimization.
Solution Approach 2:
The patent divides the connection structure into functionally distinct surfaces: the upper surface for probe mounting and the lower surface for electronic part mounting. This segmentation allows independent optimization of each area, enabling increased electronic part density without interfering with probe functionality or available mounting space.
3Volume of stationary object
If electronic parts are mounted on the lower surface of the connection structure, then space utilization is improved, but the complexity of the connection structure increases
Solution Approach 1:
The connection structure is designed to serve multiple functions: it provides mechanical support for probes on the upper surface, electrical connection pathways through the bulk material, and mounting substrate for electronic parts on the lower surface. This multi-functionality allows space utilization improvement without proportionally increasing complexity, as the same structural element fulfills multiple roles.
