I agree with DaveF's recommendation to see Foresight's website (www.residues.com). They have excellent Case Studies on display (for free). There is a good case study which references the results you can expect using a ROSE tester vs other control met

Many Thanks Davef for your continuos great tech support. From my side, I am still fighting against BIC coming with sockets ( still tons of Br-). Even the supllier is surprised about this pbm. But as we know no Standards available to control bulk ion

Hi Simon, Thanks for the immediate reply. We really appreciate it very much. Currently, we are using Class 2 for the visual inspection criteria of our telecom boards. In IPC-A-610 Rev. C criteria, there are TARGET, ACCEPTABLE and REJECT criterias.

Hi Charlie, In case you're processing large quantities of lumileds you may want to have a look at the Assembleon FS machine. It is an FCM machine of only half the length with some dedicated robots on it. In stead of all Pick&Place robots it 2 dispen

Hi Dave, Thanks for your reply. I have checked the former thread you gave to me. But I think it's totally not the same thing. I want to know, when we see the component spec -- 260 centigrade 10secs, the 260 centigrade means what? It's the environme
