Impedence Networks TRIZ Cases
- Electronic Component Sealing Film to Reduce Thermal Stress
Thin metallic or inorganic sealing films maintain pressure and humidity while reducing thermal stress and moisture ingress in electronic components.
- High-Frequency Module Recess Layout for Low-Height Packaging
Recessed substrate regions place taller RF components within the module body, cutting planar size without increasing overall height.
- Composite Electro-Optic Substrate With Rough Interface for RF Resonance
A rough low-index/support interface suppresses RF resonance and signal ripples while keeping light confined in the electro-optic crystal.
- Piezoelectric-Silicon Bonded Structure for Peel-Resistant Processing
Controlled aluminum on silicon and a metal-oxide bonding layer strengthen piezoelectric substrate bonding and suppress peeling during processing.
- Composite Wafer Bonding with Plasma-UV Activation for Void-Free SAW Substrates
Mixed oxygen-nitrogen plasma and UV activation improve piezoelectric wafer bonding strength while reducing voids, warping, and SAW loss.
- Magnetostatic Wave RF Temperature Control for Stable VHF/UHF Operation
A temperature-controlled enclosure and doped ferrite keep magnetostatic wave RF frequency stable across ambient changes in VHF and lower UHF bands.
- Thin EMI-Shielded Package Structure With Integrated Markings
A thin EMI shield layer with direct ink or laser markings cuts package thickness while preserving RF shielding and component identification.
- KNN Piezoelectric Film With Grain-Boundary Dopants for Longer Life
Cu or Mn concentrated at KNN grain boundaries traps oxygen deficiencies, suppressing short-circuiting and extending piezoelectric film life.
- Polycrystalline Substrate Orientation for High-Q SAW Filters
Controlling (101) grain content to 7%-20% raises SAW filter Q-factor while improving substrate strength and reducing bonding chipping.
- IDT Edge Dielectric Layout for Transverse Mode Suppression
Edge dielectric films lower acoustic velocity beside IDT fingers, enabling piston mode formation and suppressing transverse spurious.
- Thin EMI Shielded Package With Surface Marking Integration
A 2-6 μm EMI shield layer enables thinner integrated packages while preserving RF shielding and adding ink or laser marks for alignment.
- Composite Acoustic Filter Layout for Higher Out-Band Attenuation
An annular reference-potential wiring layout boosts electromagnetic coupling in a composite acoustic filter to raise out-band attenuation with low insertion loss.
- Integrated BAW Filter Structure for High-Frequency Substrates
A layered BAW filter structure adds acoustic absorption, mechanical support, and via-linked electrodes for high-frequency substrate integration.
- Thermal Support Substrate and Through-Film Layout for Heat Dissipation
A high-conductivity support body and through-hole conductive film create a better heat path for piezoelectric or compound semiconductor substrates.
- Piezoelectric Cantilever Structure for Medium Resonance Control
A plate-shaped section tunes the opening-side space volume to control medium resonance without shifting cantilever frequency.
- Integrated RC Architecture with Bridging Contacts for Resistance Tuning
Distributed bridging contacts tune series resistance in an integrated capacitor while limiting temperature drift and parasitic inductance.
