Printed Circuit Details TRIZ Cases
- RF Module Signal Electrode Via Holes Reduce Transfer Loss
Via holes connect semiconductor IC signal electrodes to the motherboard, reducing transfer loss and noise interference from planar line patterns.
- RJ-45 Plug Compensation Coupling for High Frequency Linearity
An RJ-45 plug uses a PCB compensation coupling with opposite polarity to counteract major capacitive coupling, resolving linearity issues above 2 GHz.
- Flexible Display Panel Bending via Material Layer Segmentation
Segmenting the support film and removing adhesive in the bending zone reduces stress on metal connections, enabling complete bending for narrow border designs.
- Chessboard Power Switch Thermal Management
A chessboard layout for power switches reduces thermal impact on middle components, extending service life.
- Movable Base Fixed Structure for Electronic Module Adaptation
A movable base fixed structure supports electronic modules via an elastic clamping portion.
- Flexible Screen Hinge with Rotating Support for Length Change
A hinge mechanism with rotating support members adjusts to flexible screen length changes during folding.
- Flexible Circuit Board Length Adjustment for Wearable Rings
A wearable electronic device uses two flexible circuit boards to adjust component positions within an annular housing.
- Flexible PCB Overlength Area for Universal Display Adaptation
A flexible printed circuit board uses an overlength area to enable 180-degree folding for universal display adaptation.
- Lead Frame Fabrication via Etched Isolated Conductive Regions
Etching a non-conductive filling material pattern on the second planar side forms isolated conductive regions, eliminating chemical carrier removal steps.
