Intermediate Water Jacket for Board Assembly Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic device test apparatuses face the challenge of increased size due to the need for multiple pin electronics cards and water jackets, which occupy space and hinder miniaturization.
Innovation Solution
A board assembly design where a single intermediate water jacket is sandwiched between two boards, with passages on both sides to accommodate electronic devices and coolant flow, allowing for shared cooling and reduced size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple pin electronics cards are held inside the test head with separate water jackets for each card, then each electronic device can be cooled effectively, but the size of the test head increases
Solution Approach 1:
The patent merges multiple separate water jackets into a single shared water jacket that serves multiple pin electronics cards simultaneously. The intermediate water jacket is positioned between two boards and provides cooling passages that accommodate electronic devices from both boards, eliminating the need for separate water jackets for each card and reducing overall test head size.
Solution Approach 2:
The intermediate water jacket is designed as a universal cooling component that serves dual functionality by cooling electronic devices on both the first board and the second board. The water jacket includes passages that open toward both boards, allowing a single component to perform what previously required multiple separate components.
2Volume of moving object
If a single intermediate water jacket is shared between two boards, then the test apparatus size is reduced, but the cooling capacity must be sufficient for multiple electronic devices
Solution Approach 1:
The intermediate water jacket is segmented into multiple distinct passages within its structure. Each passage is specifically designed to accommodate and cool electronic devices from either the first board or the second board. This segmentation ensures that cooling capacity is distributed appropriately to multiple devices while maintaining a compact single-jacket design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables a smaller electronic device test apparatus by allowing two boards to share a single water jacket, reducing overall size while maintaining effective cooling of electronic devices.
Implementation Method 1
supplying a coolant to a water jacket which is attached to the pin electronics cards so as to cool the test-use devices
Implementation Method 2
a first passage through which a coolant can run and opens toward the first inside main surface; and a second passage through which a coolant can run and opens toward the second inside main surface

AI summary
A board assembly which enables reduction of the size of an electronic device test apparatus is provided. A test module 20 comprises: a first pin electronics card 21; a second pin electronics card 22; and a single intermediate water jacket 23 which is sandwiched between the first pin electronics card 21 and second pin electronics card 22. The intermediate water jacket 23 is in close contact with the first inside main surface 212 of the first pin electronics card 21 which faces the second pin electronics card 22 and is in close contact with the second inside main surface 222 of the second pin electronics card 22 which faces the first pin electronics card 21.
