Conductive Material Mechanical Removal TRIZ Cases
- PCB Clinch Mechanism Using Rolling Toggle-Cutter Contact
Rolling involute toggle-cutter contact cuts and clinches PCB leads with lower wear and less force on sensitive electronic components.
- PCB Tape Heat Spreader Protrusions to Prevent Adhesive Contamination
Separation protrusions pressed into the heat spreader keep adhesive from squeezing out during tape rolling, protecting stacked PCB tapes and protection tape.
- Ceramic Substrate Trenching for Faster Electrode Patterning
Mechanical pre-trenching cuts chemical etching time for ceramic substrates while preserving electrode precision and supporting heat dissipation.
- Two-Conductive-Layer Flex Foil Milling from Both Sides
Separate milling wheels and cliché patterns selectively remove foil layers on both sides, improving thickness and spacing consistency.
- Fiber Composite Circuit Carrier Plate With Insert Gaps
A fiber composite circuit carrier plate uses filler material in gaps between inserts and the base body to join components.
- Fine Interconnect Circuit Board Dry Wet Etching Method
A subtractive circuit board manufacturing method uses dry etching to form grooves before wet etching.
- Light-absorbing mask layer for high-purity functional material deposition
Pulsed light heats a light-absorbing layer to generate gas, releasing pure functional material from wells without additive interference.
- Circuit Board Gold Finger Routing for Copper Sheet Warping
Forward and reverse routing with preliminary drilling prevents copper sheet warping during machining.
