An opens and shorts test can be programmed in a few hours. Debug at least
twice as long. 
With probes on the top only, coverage will not be very good, unless the
board is designed for test. 
Expect the test to run for 45-60 minutes. A complex board can run a couple
of hours. 
You will need a really good technician or engineer to program and debug.

Subject: [TN] flying probe testing - benefits and drawbacks?

Good day TechNet
We have a customer asking us to look at implement flying probe testing on
their products.  We currently do AOI on all, and x-ray and functional test
on some of their products, we do not have a flying probe machine.

I've got some notions of the benefits and drawbacks of these machines but as
I have no first hand experience I figure I should ask here for opinions.

Assume an entry level machine for the sake of discussion, and without
significant add-ons.  Top side probes only, probably 4 probes.
Assume a double sided board with 500 components, only passives on the bottom
side, and fair accessibility.

My questions:
- Claims are that the current crop of machines can be programmed in "a few
hours", is this realistic?

- Do I need anything from the designer on top of the usual gerber and BOM
(e.g. a netlist, or other format of data?)

- What kind of run time am I looking at?  I understand with a single side
machine I will have to run the board twice to get the best coverage
possible.

Thanks!  Any opinions are appreciated.
