We have our waste water tested periodicially by a local lab to ensure that we are in compliance with local discharge regulations and as part of ISO14001 approval. This analysis includes levels of metals as well as organics, but it will tell you littl

Hi George, Depending on your product, wave soldering twice is not all that bad. Residues will be higher, but should only be cosmetic unless your product is sensitive to ionic contamination. You can set-up an alternate profile on your wave for 're-

hi davef, thanks for your kind replies...i have a batch aqueous cleaner in my process...but we are going to have AS9100 Audit 3rd quarter of this year...do I need to purchase a tester? right now we are sending sample boards to a 3rd party company bu

Tim, try and incorporate an inline wash system. We use one with a surfactant and it cleans the "NO CLEAN" fluxes well. If you dont have an inline system, you can manual clean the boards with an surfactant and IPA. You can also do an ionic contamin

Yes, providing your: * Inbound material does not compromise your process. * Soldering processes apply the proper amount of flux and activate it properly * Material handling does not contaminate your boards Recognize that the IPC requirements of less

Thank you all for your replies. I guess my age in this industry is showing. This military spec. does not appear to be in existance. So, let me make my request a little more to the point: Is anyone aware of a specification specifically referencing

Comments are: * Use an eraser if the surface of Au is not clean, but make sure the eraser has no/low ionics (such as sulfur that is a common additive for rubber). * If the plating surface required eraser to remove the top surface, the plasma normally

Good day everyone, I'm hoping that there are a few of the Westek Ionic Contamination Tester systems out there... I am in need of standardization solution for this unit and my current suppliers have dried up. I was purchasing from Stoelting, #1-67

Q1: static or dynamic? A1: search the fine SMTnet Archives. For instance, http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=44837 Q2: localized testing (C3) or bulk testing (Omegameter/Zero Ion)? A2: depends on the contamination that you're

Resistivity Of Solvent Extract [ROSE] is a bulk ion contamination [BIC] test method. It should thought of as a process control tool used to assess ionic contaminants. Don't consider it an acceptable tool for establishing 'GO-NOGO' limits. The stan
