We are considering the purchase of a Teradyne Spectrum 8800 series tester. We have experience primarily with Genrad 228X testers, and have been well pleased, but we are giving Teradyne the opportunity to bid. Does anyone have experience with these

The selection of Test equipment primarily should be driven by the requirement of fault spectrum you would like to capture. If you are looking at Manufacutring defects MDA/ICT would do the job, if you would like to cover the functional aspect a combin

Thanks for the explanation but we dont have a need for a JEDEC tray or matrix tray feeder. My volume is half million pieces a year so we are on the small side of the spectrum.
