Thanks to all who responded to my request for names of Equipment Manufacturers of Moving
Probe Bare Board Testers.
The units being considered are:
Probot QC2000, Integri-Test Model 4800, Mania "Speedy", Lavenir MP-220, Teradyne Flying
Prober, Circuit Line Precise FP, ECT/BSL Eclipse Linear Prober (I or II?), Leading Edge
Devices Flying Grid Tester, and Matrix M864 Flying Grid Tester.
There is no front-runner at this time. I have nothing to go on but price, currently.
No one, however, provided any feedback on how well the machines performed for them. Can
anyone share experiences they had? Has anyone made meaningful benchmark
comparisons of any of these machines? Does anyone have a recommendation or caution?
*** If you are concerned about your vendors reading this, reply to me offline. *** I will share
the response I get (without revealing sources) with TechNet, once compiled. If you want
TechNet folks to know your response, post it to the TechNet.
Which machine(s) has the fastest throughput using the same PCB and database?
Which manufacturer(s) provides the most reliable support?
Is the board holding device adequate, thus minimizing poor probe contact due to SAG?
Is the probe force against the PCB adjustable, allowing good contact without damaging PCB
features? Does the probe force adjustment mechanism work well?
Which machine(s) have the most efficient setup?
Are there any horror stories out there (or warnings) regarding the performance in any area for
any of these machines?
What are the Pros and Cons of the various Test Methods ((N-squared, Discharge,
Capacitance, Phase Difference)?
Does anyone have a documented time study for any of these machines which should include
the following information:
1) Setup Time
2) # of Test Points
3) # of Nets.
4) # of Layers
5) # of Adjacent Nets
6) Panel Size
7) Test Parameters
8) Avg Time to test 1 PCB described above
9) Test method (N-squared, Discharge, Capacitance, Phase Difference)
10) # False Error Tests (i.e. good parts that tested bad)
11) # Escapes (i.e. bad parts that tested good)
Thanks, in advance, for any response I may get.
