PCB Sensor Pre-Inspection via Hollow Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printed circuit boards are inspected and programmed after installation, leading to wasteful discarding of defective boards along with the housing, increasing costs due to inefficient inspection and programming processes.
Innovation Solution
A printed circuit board design featuring a board main body, sensor, and hollow-structured electrical conductor with external connection pads allows for pre-installation inspection and programming, enabling separate evaluation and processing of the sensor board before integration, using a connection terminal system for stable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inspection and programming are performed after installation in housing, then the printed circuit board can be tested in its final configuration, but defective boards must be discarded together with the housing, increasing waste and costs
Solution Approach 1:
The patent enables inspection and programming operations to be performed on the printed circuit board before it is installed in the housing. The connection terminal protruding from the housing allows external connection to the printed circuit board for these operations prior to final assembly, so that defective boards can be identified and replaced without discarding the housing.
2Reliability
If the printed circuit board is inspected after installation, then the complete system can be tested, but the process becomes less efficient and more costly
Solution Approach 1:
The connection terminal enables preliminary inspection and programming of the printed circuit board before housing installation. This allows for efficient testing and programming operations to be completed separately, improving overall productivity while maintaining system functionality verification.
3Adaptability or versatility
If programming is performed after installation, then the printed circuit board can be configured for its specific application, but defective boards increase costs
Solution Approach 1:
The connection terminal allows programming operations to be performed on the printed circuit board before it is installed in the housing. This enables the printed circuit board to be configured for its specific application in advance, and if defective, can be replaced without discarding the housing, reducing waste and costs.

AI summary
A printed circuit board comprises a board main body, a sensor, an external connection pad, and a hollow-structured electrical conductor. The board main body has a top face and a bottom face opposite the top face. The sensor is mounted on one of the top face and the bottom face of the board main body. The external connection pad is provided on the top face or the bottom face of the board main body opposite the sensor. The hollow-structured electrical conductor extends through the board main body and electrically connects the sensor to the external connection pad.
