Whatever, we process the cover tape to troubleshoot the provlem.

Yes 0402 8X4 embossed feeders exist for Panasonic MSR, Universal GSM, Contact Systems, and Mimot for sure. In the old days of 0402 components, 0402 resistors used to come in 8X4 paper tape but now I think most 0402 resistors and capacitors come in 8
