Edmund: Responding to your questions: 1 What is purpose of using DI water to wash a PCBA? Compared to tap water, DI water is less likely to leave: � Metal cations on sensitive components. � Salts of Ca, Mg, and other stuff on metals on the assemb

Hello Dave, Before I get into waste management, I must first stress the importance of checking with your local regulating agencies. Every area can be and usually is different. California regulations differ from Ohio and Ohio�s are different than Mu

On a more layman's terms (am not a expert), here goes : 1) resistivity of DI rinse must be greater than 10M-ohms (some say greater than 16M-ohm?), dunno what is the FIX industrial standard? 2) DI water rinse usually is the end zone rinse, before th

Hesitating after your shout-out for �DI water rinse experts�, Q1: �What is the FIX industrial standard?� A1: Never heard of �the FIX industrial standard�. There is no standard in the US electronic industry. The issue: * Is NOT the cleanliness of

The most common method is a R.O.S.E tester. They have been around for 30 years and are an industry standard for ionic contamination (flux and other residues) testing. Manufacturers include: Zero Ion www.aqueoustech.com Omegameter / Ionagraph http:/

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

I have experience cleaning NC for military boards. The reason for cleaning the NC is due to conformal coating requirements. Zestron Vigon A200 and Atron AC 100, as well as Petroferm Hydrex DX have both been effective at cleaning Alpha UP78 NC paste.

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee

Mr. Wizard is not currently available. You get the wizzer. Maybe your dream date will show later. Get your own lab tests done. Show your potential customer that your boards are clean. That�s the issue. The issue is not how you go about cleaning
