The Omegameter (or Ionograph) detect contamination by measuring the conductivity of the solution used to extract the board. This conductivity number reflects the sum of all of the ionics in the extraction solution. Unfortunately, we can't sort out th

Barney, Please tell me who it is that told you this customer cannot get support. Certainly it is not the customer himself. We have been at this customer with top level engineers at the drop of a hat from day one. As for the C7 it is part of the new

I am a Quality Engineer which went from an Automotive QS9000 company manufacturing ceramic hybrid boards and now I am with a ISO PC mfg. company dealing with PCBA boards. I've been assigned a task in determining the contributing factor to high contam

Thanks for the information. davef, I will search for and review the Ion Chromatography for Ionic Cleanliness test method. This definitely is the test I want to perform. Do you know what the IPC specification is using this test method? The outside

The alloy I have chosen uses a wetting angle of 50-70 degrees. Different alloys have different properties. I coupled experimental data with what others have published. Nothing new here. As for reliability...I think you'll be surprised what lead fr

Dhanish, If I understand correct your ICT doesn't detect shorts and only measures capacitive and resistive values. The webbing as Ken mentioned would have a resistance because this is caused by a lack of flux and the web is mainly tin oxide, which w

We approached it the same way we select SnPb pastes. We started by doing coupon level tests to sort out the obvious "bad" pastes: SIR, wetting, solder balling, print quality, etc. That cut the field in half. From there we started to do assembly l

Rob..... First off...Sorry if you have had an issue in the past, but please know that not every customer has your opinion about our legacy software. UIC's policy is not to charge for s/w "fixes" for at least the first year from initial purchase. We f

Hello Arnold, Just to clarify the Sn100C discussion: Please note that SN100C is the Nihon Superior alloy composed of tin/.7copper/nickel. The key point in regard to SN100C is that Cu does not go directly into solution but first reacts to form an inte
