We describe the technical layout and the expected performance of the Barrel Time-of-Flight detector (Barrel TOF) for the PANDA target spectrometer, giving updates on recent developments. The Barrel TOF detector has been designed to precisely measure the time at which a charged particle transits the detector with a resolution superior to the other sub-detectors. It will signal the topology of physics events, hence setting cornerstones for event classification. The implementation of the Barrel TOF is based on very fast organic scintillator tiles coupled to Silicon Photomultipliers. In total 2000 scintillators and 16k SiPMs will be used, covering 5 m2. The detector R&D is now in advanced stage and the technical design report is being reviewed by FAIR council.
The emphasis of this talk will be put on the updated design and performance of the PCB stripline transmission and fine scans of the time resolution of the detector elements, continuing the updates for the B-TOF detector.
