Manufacturer Narrative

A review of the manufacturing records showed that all requirements were met.Service confirmed damage to the tip membrane along the radio frequency trace.Investigation found stress concentrations on the flex assembly at the adhesive edge that damaged the radio frequency trace, causes arcing and subsequent burn-through of the flex circuit membrane.Based on the available information, this event was most likely caused by damage on the tip membrane.The final test verification specifications are acceptable.No non-conformities or anomalies were found related to this complaint when reviewing the device history record.
