Sir, I asked 3 or 4 questions. If it's easier, you can email me.

Splitting hairs is putting it mildly. I�m just trying to rule out all variables. It doesn�t appear that we have an SIR problem, but since the newest variable is OSP (blame the new guy for all the problems), I have to consider it. I�ve seen this befo

Thanks for your fast respond Dave & Slaine. It was much appreciated. Dave, I'm not familiar with the ion Chromatograph testing i.e. how different it is versus SIR, but you could be right. May be they have mistaken this. Let me try to search for som

Mr Lao We have some specialist knowledge on this subject and offer both equipment and services for these tests. My first recommendation is that take coupons manufactured by your PC Fabricator and then samples at each manufacturing stage: Bare coupon

�What does 5 micrograms of chloride mean to me?� * With SIR testing, you can show no detrimental leakage currents under humid conditions, no corrosion, no metal migration, which are the big factors in figuring out electrochemical reliability. People

1. Most ionic testing is measured in NaCl, that is, the ionic residues are quantified in terms of NaCl equivalence. The test does not determine what the ionic residue is, just its relative strengh. 2. I use IPC cleanliness specs on OA fluxes but n

Wow, good luck. None of my test results would be helpful since we use IPC-B-24 test boards as received from our board suppliers so we have a clear understanding of what we're shipping customers, not necessarily paste performance alone. We'll only cl

The heat from a soldering iron will push raw flux across the surface of the board and into surprising places. It's bad practice to squirt liquid low residue flux on the board during rework, because the portion of the flux that does not get heated pr
