Fire away. It's the obvious one you should be looking for.

What's wrong with this BOM ?
"Eeyore" wrote in message Fire away. It's the obvious one you should be looking for. No resistors, except for a few resistor networks. The power fuse is 3.2A for Europe and 1.6 for US, which seems backwards for 220 and 110 volts. -- Reply in group, but if emailing add one more zero, and remove the last word. |

You mean other than it is 22 frikkin' pages long when it could be reduced to
a quarter of that for a true BOM rather that what it is ... a reference designator list. Jim -- "It is the mark of an educated mind to be able to entertain a thought without accepting it." --Aristotle "Eeyore" wrote in message ... Fire away. It's the obvious one you should be looking for. Graham |

Neve had a neat way of dealing with that. You had a BOM for assy XYZ, then the mechanical parts were assy XYZ-KOP (kit of parts). After all, the pcb stuffing machine can't fit them ! Graham |
