Flying Probe Testers?

Flying Probe Testers? | 17 August, 1998

Good Day All!! I hope ya'll had a decent weekend, I did...didn't do a damn thing, I like weekends like that. Anyways, the big guys here are thinking about buying a "Flying Probe" tester, and the G.M. came to me and asked what I thought of them. I had to plead ignorance, I didn't know much about them at all. So I've been trying to learn something about them. I've done a web search and I could find a mess of bare board moving probe testers, but not many ICT testers. The two companies I've found are Tescon, and Genrad. From what I've learned, Tescon has been building flying probe testers for a while, while Genrad is just coming out with theirs. I've learned that flying probe testers can actually test denser boards than a fixed probe station can, but that is at the expense of cycle time. Cycle time won't be something that we'll be too concerned with, as we don't plan on doing any high-volume stuff. I was wondering if any of you guys have worked around a flying probe tester? If so, other than the slow test times, what is the biggest gripe you have about them? Who are the other vendors besides Tescon and Genrad? I did see a couple of european companies, but from what I could tell on their web sites, they don't market them in the states. From the experiences any of you have had with them, is there any vendor any better than the other? Sorry about all the questions, but I'm pretty clueless about them... Thanks for any info! -Steve Gregory-

Steve: Take a look at the attached url. As with all testing systems, tooling / fixturing is costly. But, not as bad as a bunch of "Bed of Nails" test fixtures. Glad you had one of those great weekends, had to spend mine fishing,, again ,, Caught a 7 pound nothern, big for our little lake. Wayne

If you have a problem with any of your designs after reflow ie they are not flat this where this system can be a problem. They work fine but are not as tolerant as bed of nails fixtures.

Things I don't like about flying probe automatic testers are: 1 Expensve: $130k stock 2 Slow compared to a MDE. Take a deep breath, you could need three or four of these things. 3 It's just a MDE 4 Programmers are not easy to find. Don't let them kid you about CAD data. As you know, you might get pad centroid data from your CAD (your customers CAD), but a functioning program is a long stretch from there. For instance, you probably can't use the centroid data because the component lead or body is sitting there. Plus you have to characterize the component measurement for each supplier. For the money I'd buy two AOI's. TTYL Dave F

WE LOOKED PRETTY HARD AT THESE THINGS BUT THE TIME INCORPORATED WITH GETTING A PROGRAM UP ACTUALLY WOULD FORCE US TO BRING ON ANOTHER INDIVIDUAL FOR THAT EQUIPMENT. NOT WORTH IT. FOR MY OWN KNOWLEDGE, IS MDE THE SAME AS MDA?? I'M KIND OF "TEST-ILLITERATE." JUST LEARNING THE GAME. REGARDS, JUSTIN MEDERNACH
