RF Test Socket Segmented Contact for Antenna Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio frequency test sockets for LTE terminals require damaging the mainboard to manufacture a passive jig for antenna testing, leading to inconsistencies between passive and active boards, and necessitate remanufacturing when the mainboard or manufacturer changes, resulting in inefficient testing and potential damage.
Innovation Solution
A novel radio frequency test socket and cable design that allows unified testing of antenna jigs without damaging the mainboard, using a metal sheet with elastic connections and an insulated push pin to disconnect and reconnect the test cable, enabling bidirectional testing by changing the insertion direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radio frequency test socket is used for antenna testing, then the antenna can be tested, but the mainboard must be damaged to manufacture a passive jig
Solution Approach 1:
The test socket is segmented into multiple independent contact points (first contact point, second contact point, third contact point, fourth contact point) that can be independently connected or disconnected. This allows the antenna testing function to be separated from the mainboard, eliminating the need to damage the mainboard while maintaining testing capability.
Solution Approach 2:
The test socket acts as an intermediary device between the test cable and the antenna/mainboard system. By introducing this intermediate component with elastic apparatus and contact points, the system enables antenna testing without directly modifying or damaging the mainboard, thus resolving the contradiction between testing capability and mainboard integrity.
2Measurement precision
If a radio frequency test socket is used for antenna testing, then antenna testing is enabled, but passive and active board performance measurements become inconsistent
Solution Approach 1:
The test socket is designed with multiple contact points and elastic apparatus that enable it to serve multiple functions: it can connect the test cable to the antenna for passive testing, and also maintain connection to the mainboard for active testing. This multi-functionality ensures that the same test socket structure is used for both passive and active board measurements, guaranteeing measurement consistency across different testing modes.
3Measurement precision
If the mainboard is damaged to create a passive jig, then antenna testing is possible, but remanufacturing is needed when mainboard or manufacturer changes
Solution Approach 1:
The antenna testing function is extracted from the mainboard by using a separate, standalone test socket with its own contact points and elastic apparatus. This extraction makes the testing system independent of the mainboard, so when the mainboard or manufacturer changes, the test socket remains unchanged and no remanufacturing is needed, thus improving adaptability while maintaining testing capability.
