Hi folks,
Sort of related to Paul's recent question about milling holes ...
Wall warts (plug packs) often come with a coaxial plug that mates with a
pcb mounted socket that has 3 flat metal tabs that are meant to fit
through slotted holes in the pcb. Following delivery of all of my boards
from the Chinese pcb house with single drill holes instead of slots, I
am trying to understand what went wrong. He was told by me when
requesting a quotation and at the time of order placement, that J1 had
to have its 3 holes milled. These were shown on the milling layer. He
says that slots 1 mm wide are always done by drilling and not milled. Is
that correct in your experience?
More importantly, how should the slotted hole be defined to avoid a repeat.
Thanks,
Ross
