Application context
Portable monitors, diagnostic instruments and body-worn sensors can benefit from three-dimensional interconnect packaging. The engineering review must distinguish a concept demonstration from a qualified device design.
Requirements to define
Document cleaning agents, moisture exposure, temperature, installation folds and repeated motion. Define whether a field-replaceable module is required. A more integrated assembly can reduce interconnect count while making repair more difficult.
Evidence to request
Request material and lot traceability, revision-linked inspection evidence and the validation records required by the device program. PCB fabrication evidence does not establish medical-device approval or clinical suitability.
Prepare your project review
Submit the board outline, region-specific stackup, bend diagram, fabrication data, quantity and required timing. Identify the part revision and mark preliminary information. Include the application-specific acceptance requirements so engineering and purchasing evaluate the same scope.
