We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

HI can anyone tell me if they ask there board houses to hold to a max amount of contamination NaCl per sq /in on there incomming bare boards, I have a Ionograph 500SMD and have been testing some of the bare boards comming in to stock, some are much

5 micrograms per sq. cm. is actually not too clean. The maximum military allowed post-clean, on-board contamination is 5.7 micrograms of NaCl /cm squared (when using the Zero-Ion brand ionic contamination tester). We are use to seeing cleanliness re

Military and most commercial standards requires post-soldered boards to measure less than 10 �g/in of NaCl (14 when using an Omegameter, 20 on a Ionagraph, and 37 on a Zero-Ion). As Dave stated, 6.5 �g/in of NaCl is called out in Mil-P-55110 for ba

How does no-clean flux residues on a PCB assembly impact the ROSE testing? Does no-clean flux residues on the PCBA dissolve in solution of ROSE tester and increase ionic contaminants level in terms of NaCl per surface area? Is ROSE tester solution (a

Hi all experts, I have no background about PCB or SMT process. I am now encountering some issues after SMT - Unstable stitch bonding condition. I am now suspecting some contaminants remain on lead after cleaning. Therefore, how can I check th

your comments will be appreciated, please; IC tests have been performed on two kind of Raw PCBs (HASL) samples by adopting three different methods : First Sample (supllier A) - Omegameter 600 SMT, solvent=40�C: extratcing time 10 min result = 0.2

Rich An excellent question and one which is often totally ignored. If you wish a "no-clean" flux to be as safe as it possibly can be, the PCB and the components must all be contamination free (ionic and non-ionic). Only then can you be sure that the
