Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual pressing of circuit board preforms onto colloids during manufacturing is non-uniform, leading to potential warping and separation issues, especially for rigid-flex boards, which can be damaged during cleaning processes due to uneven pressure.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pressing is used to bond preform to colloid, then operation simplicity is maintained, but pressing uniformity deteriorates causing warping and separation
Solution Approach 1:
The patent replaces the manual mechanical pressing system with an automated pressing mechanism that applies uniform pressure through a pressing member. The automated system uses controlled mechanical motion to ensure even distribution of pressure across the preform surface, eliminating the non-uniform pressing caused by manual operation while maintaining ease of operation through automation.
Solution Approach 2:
The pressing member is designed to automatically adjust and distribute pressure uniformly across the preform during the bonding process. The mechanism includes features such as a pressing surface that contacts the preform and applies force through a controlled path, enabling the system to self-regulate pressure distribution without requiring manual intervention to achieve uniformity.
2Adaptability or versatility
If rigid-flex board is pressed manually, then operation flexibility is maintained, but pressing consistency deteriorates leading to damage during cleaning
Solution Approach 1:
The patent replaces manual pressing with an automated pressing mechanism that provides consistent and reliable pressure application. The automated system ensures uniform pressing across the rigid-flex board, preventing warping and separation that would occur with manual pressing, thereby maintaining reliability while preserving adaptability through automated control.
3Manufacturing precision
If automated pressing with multiple portions is used, then pressing uniformity is improved, but device complexity increases
Solution Approach 1:
The pressing member is divided into multiple portions or sections, each capable of independently applying pressure to different areas of the preform. This segmentation allows for uniform pressing across the entire preform surface while keeping each individual portion relatively simple in structure, thereby achieving high pressing uniformity without excessive overall device complexity.
Solution Approach 2:
The pressing member extends in multiple dimensions or directions to contact different areas of the preform simultaneously. By designing the pressing surface to span across the preform in a multi-dimensional configuration, the system achieves uniform pressure distribution without requiring complex multi-component assemblies, thus improving pressing uniformity while controlling device complexity.

AI summary
A pressing member includes a base, a first pressing portion, and a second pressing portion. The first pressing portion and the second pressing portion are arranged on a same surface of the base. The base is provided with a first hole. The first pressing portion includes a first contact surface facing away from the base. The first contact surface defines a second hole extending toward the base and communicating with the first hole to cooperatively define a channel. The second pressing portion includes a second contact surface facing away from the base. The second contact surface and the first contact surface are arranged on a same plane.
