medium to large defence companies tend to have in house board fabs. I worked in one.

yes, what was the utilization like?

  • 20-40% capacity. Reserve available. Turnaround same day on a board (2 layer). Next day 4 layer. Two days exotic (rogers etc). Pick, place, soldered 2 days or delivered to lab immediately after panel cut.

    If they had a fast production run in they could extend to 24 hours operation and triple base capacity.

    They did a fair bit of TH though which was manually stuffed and wave soldered which could slow stuff down considerably.
