PCB Integrated Connector for Data Storage Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data storage devices with separate connectors are costly and complex to manufacture, particularly due to the challenges in forming guiding structures for SATA and μ-SATA cables, which complicates the manufacturing process.
Innovation Solution
A data storage device with an integrally formed connector on the PCB, featuring connection tabs, dummy tabs, and guiding members made of insulating materials like epoxy molding compound, which simplifies the manufacturing process and reduces costs by allowing simultaneous formation of these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate connector is used to connect the PCB with SATA/μ-SATA cables, then the electrical connection reliability is improved, but the manufacturing cost and process complexity increase
Solution Approach 1:
The patent merges the separate connector component with the PCB by directly forming connection tabs and guiding members on the PCB itself. The connection tabs are formed through metal plating processes on the PCB edges, and guiding members are formed through molding or adhesive bonding directly on the PCB surface, eliminating the need for separate connector assemblies and reducing manufacturing complexity while maintaining reliable electrical connections.
2Ease of operation
If a separate connector with guiding structure is used, then the cable insertion guidance is improved, but the manufacturing cost increases
Solution Approach 1:
The guiding members are merged with the PCB by forming them directly on the PCB surface through molding or adhesive bonding processes. These guiding members are positioned to align with corresponding guides on the SATA/μ-SATA cables, providing effective insertion guidance without requiring a separate connector component, thereby reducing manufacturing cost while maintaining ease of operation.
3Ease of manufacture
If an integral connector formation on PCB is used, then the manufacturing cost is reduced, but the guiding structure formation becomes more difficult
Solution Approach 1:
The guiding members are segmented into discrete elements that can be independently formed on the PCB surface. This segmentation allows the guiding structure to be created through simpler molding or adhesive bonding processes rather than requiring complex integrated forming operations, reducing the overall complexity of forming the guiding structure while maintaining manufacturing cost benefits.

AI summary
A data storage device includes a printed circuit board (PCB), a connection tab, a dummy tab and a guiding member. A memory chip is mounted on the PCB. The connection tab is formed on a first surface of the PCB to electrically connect the PCB with a first cable. The dummy tab is formed on the first surface of the PCB. The guiding member is formed on the dummy tab to guide an insertion direction of the first cable. Thus, the data storage device without a separate connector may be manufactured by a relatively simple process at a lower cost.
