Looked up the attributes with ??? question marks
- according to https://nginx-hgtddb.app.cern.ch/listattributes only one hybrid is registered that has entries for those attributes: 20WHY100000001
- Location: China (so where the part is located on a large scale, not inside detector itself)
- Mounted: on a PCB
- Status: good (so a flag with few options)
- Comments: PI on WB pads (don't know what this means)
- but this hybrid is not found when looking for it in https://nginx-hgtddb.app.cern.ch/partslist
- I am not sure if the attributes are needed, if they are only in use for a hybrid that is not shown on the public list of parts
