Test Head Side Opening for Board Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test apparatuses require the removal of the connecting section from the test head to exchange test boards, which is inefficient and increases capital investment by not allowing for easy reuse of existing equipment.
Innovation Solution
A test head design with a casing that allows for the insertion and removal of test boards through a side opening, using a mounting member to guide and secure the test boards, enabling easy exchange without removing the connecting section, and allowing multiple test heads to share a single connecting section for increased parallel testing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting section is removed from the test head to exchange test boards, then the test board can be exchanged, but the operation time increases and equipment reuse efficiency decreases
Solution Approach 1:
The invention separates the test board from the connecting section, allowing the test board to be independently inserted into and removed from the test head without affecting the connecting section. The test head includes a casing with an opening that accepts the test board, while the connecting section remains mounted separately, enabling independent exchange of test boards.
Solution Approach 2:
The test head casing serves multiple functions: it provides structural support, guides the test board into position through mounting members, and maintains electrical connections. The opening in the casing allows the test board to be inserted and removed while the connecting section remains in place, making the test head universally applicable for exchanging different test boards without reconfiguring the connecting section.
2Adaptability or versatility
If the connecting section is removed to exchange test boards, then test board exchange is possible, but capital investment increases due to inability to reuse equipment
Solution Approach 1:
By segmenting the test head system into a reusable casing with mounting members and exchangeable test boards, the invention allows the expensive connecting section to remain mounted on the test head while only the test boards are exchanged. This segmentation enables equipment reuse and reduces the need for additional capital investment.
Solution Approach 2:
The invention allows test boards to be discarded (removed from the test head) and recovered (reused in other test heads or configurations) without affecting the connecting section. The connecting section remains in place and can be reused with different test boards, maximizing equipment utilization and reducing capital investment requirements.
3Productivity
If multiple test heads share a single connecting section, then parallel testing capacity increases, but the complexity of managing multiple test heads increases
Solution Approach 1:
The test head casing and mounting member design creates a universal interface that can accommodate multiple test boards. A single connecting section can be mounted on a test head and serve multiple test boards simultaneously, as each test board independently interfaces with the connecting section through the standardized opening and mounting mechanism.
Solution Approach 2:
By segmenting the system into independent test head units with standardized casings and mounting members, the invention allows multiple test heads to be managed separately while sharing a common connecting section. Each test head operates independently but can be easily configured and exchanged, reducing the overall system complexity despite increased parallel testing capacity.

AI summary
A test board can be inserted to a test head and removed from the test head while the connecting section for mounting thereon devices under test is mounted on the upper portion of the test head. A test head for retaining therein at least one test board for testing devices under test, includes: a casing provided with, on one side surface thereof, an opening through which the at least one test board is inserted and removed, the casing retaining therein the at least one test board with an upper side thereof oriented towards an upper surface of the casing; and a mounting member that guides a lower side of the at least one test board through the opening to a pre-set position, imposes an upward force to the lower side of the at least one test board, thereby mounting the at least one test board to the casing.
