Molex KK 254 series drill size too big (conn_molex_kk_254_tht_top.py)
Hello,
I've been using multiple pin variants of the molex KK 254 serie connectors on one of my PCB's, but when I ordered the PCB and fitted the connectors in it was possible to rotate the connectors in place quite much. Looking into the code here I found out that the drill size is oversized compared to the KLC 7.6, which describes a hole size of the maximum pin diameter + 0.2mm in size. I would expect the size to be set to ~0.84mm AFAIK since using a bigger hole size adds up an excessive amount of solder necessary for creating a proper connection and the rotation problem as well. Also I couldn't find any reference about this "minimum 1.1mm drill size" (as mentioned in the comment of the previous code link) in the manual (maybe something of old times?), so is there another reason for making the hole diameter this big?
