Rigid-flex packaging for a compact communications module
Packaging a communications module with rigid-flex requires a coordinated mechanical and RF review.
Rigid-flex planning for an automotive sensor module
A rigid-flex board inside an automotive sensor module should be planned around the sensor datum, housing attachment points, connector interface, and…
Rigid-flex architecture for a wearable sensor
A wearable sensor architecture should begin with the locations of the sensing surface, battery, radio, and mechanical supports.
Rigid-flex cost drivers: a procurement worksheet
A useful rigid-flex cost comparison starts with matched requirements and quantities. Separate one-time charges from recurring unit prices, identify what ea
Bare-board electrical testing versus functional testing
Bare-board electrical testing and functional testing answer different questions. A bare-board test examines specified electrical properties before componen
ENIG versus hard gold: start with the pad function
Choose a PCB gold finish by the job the surface must perform. A solderable component pad, a repeatedly mated contact, and a bonding surface should not be t
From fabrication data to a rigid-flex process plan
A useful rigid-flex manufacturing handoff connects each released file to a defined part revision and explains which information governs the construction. T
Impedance targets across rigid and flexible regions
A shared impedance target does not automatically imply one trace geometry throughout a rigid-flex PCB. Review each region using its actual construction and
Reading a region-specific rigid-flex stackup
A rigid-flex stackup must be read by region. A layer present in a rigid island may be absent from an exposed flex span, so a single overall layer count is
How to define rigid and flex regions in a fabrication drawing
A rigid-flex PCB fabrication drawing should let a reviewer identify each region, locate its boundaries, and connect it to the correct stackup without guessing. Start with a dimensioned flat view, give every rigid island and flex section a stable identifier, and use those identifiers consistently across the stackup, bend notes, and manufacturing outputs. This guide […]
