Simple answer is no, there is no universally acknowledged acceptance criteria. Some time ago, I started a spreadsheet with the acceptance levels suggested by various labs on the individual ionic species. All are relatively close in their individual

I am looking for an industry standard �stock� note to place on our printed circuit board assembly drawings that will capture a level of cleanliness for an IPC-A-610 class 2 board assembly. I�m looking for some quantitative spec for cleanliness that w

My customer is finding a blue haze on some SMT pads after processing, kind of looks like a water spot on the surface of solder joints. It requires 20x mag and very good lighting to see. We have done 2 different ionic tests and the boards pass to clas

Has anyone tried to get conformal coating under a BGA? (large package MPC555). There is a concern with ionic/metal bridges developing between contacts due to accumulation of dust/humididty. Final product is Class 3 (aerospace). Thanks, Carol

Hi Guys, Maybe you could help me with the above. We are doing IPC Class 3 products and would like to know more about the difference between the 2. We have an Omegameter, do we need an Ionograph too? Which one between the 2 is effective in Ionic Cont

Wayne, I think Dave and Justin are correct but I would just add my twopennworth: Your customer presumably wants to know if the end-product will be reliable? If he/she wants you to prove cleanliness, ask them for the spec they want to work to and app
