Hi Everyone, I got an approval to buy a Ionic Contamination Tester in my company, hence i require expert advise to proceed further for machine procurement At present I've fixed for Zero-Ion G3 Ionic Contamination of Aqueous Technologies and SMD V T

Dave, Ionic contamination testers are considered to be a valuable tool to determine the cleanliness of both bare boards and post solder boards. There are some instances when SIR testing is more suitable for determining cleanliness than ionic contamin

thanks a lot sir davef. which is better between the two, static or dynamic? localized testing (C3) or bulk testing (Omegameter/Zero Ion)? do I really have to purchase this unit despite having an aqueous cleaner? thanks again...

If you�re running chemistry in the wash, the wash temperature will be influenced by the chemical manufacturer�s recommendations. Typically, wash chemistries recommend operating temperatures between 130F and 150F. If your application is straight D

Immersion metal baths also rely on alchemy-like magic. If you take a piece of copper and dip it into an aqueous solution of silver ions: Presto Chango! Within seconds the copper will be coated with silver. Of course, there is some additional magic re

We do cleanliness testing each morning using a Zero Ion tester. Our pass/fail number is set at 37ug/square inch NaCl. We are rarely above 10ug/square inch NaCl. We use Aqueous flux. Our inline washer has a prewash (70psi@130 degrees F), wash (?psi),

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani

Patrick, When you say "no-residue" what exactly do you mean? Is there truely "no-residue" or is it "no visible residue"? What type of ionic contamination results have you experienced? If you take a bare board that measures 0.0 NaCl and reflow it
