Printed Circuit Assembling TRIZ Cases
- User-Replaceable Electrical Connector Isolates Mechanical Stress
A user-replaceable connection system isolates mechanical stress from circuit boards using a sacrificial mounting element.
- Hollow Shielding Structure for PCB Elements
A hollow shielding structure with a gap between the shield cover and circuit elements on a printed circuit board.
- Soft Solder Transfer via Physical Vapor Deposition
Physical vapor deposition creates a soft solder layer on a carrier for mechanical transfer to component mounting surfaces.
- PCB Solder Resist Gap for Reliable Optical Module Contact
A printed circuit board design maintains a gap between solder resist and electro-conductive contact sheets to ensure proper electrical connection.
- Sn Alloy Joining with Cu-Ni Insert for High-Temperature Reliability
A Cu-Ni insert material forms intermetallic compounds with Sn, eliminating residual Sn and preventing air gaps in high-temperature joints.
- PCB Panel Cavity Reinforcement for Heat Deformation
Extended cavity stays reinforce the PCB panel to prevent heat-induced deformation during soldering and cutting.
