Flux Residues In Lead Free Wave Soldeing Process

Electronics Forum | Sat May 27 02:52:20 EDT 2006 | TimS

Gentlemen I have managed to pull myself together after banging my head. I am not sure the flux volume is the total solution here. All spray processes deposit flux in a similar manner, that is to say the vast majority of material sprayed onto the PCB

VOC-free fluxes

Hi! I recently remarked on a thread that so-called VOC-free fluxes weren't. As a result, I got three private e-mails asking what I meant. As this seems to be unclear, I'm starting a new thread with my explanation, rather than sending out the answers

| | | | Can someone suggest what material I have to use to protect components by electrical discharge on ptfe based boards? | | | | It should have high resistivity, thermal stability (-40 +70 'C),perfect adherence on ptfe... | | | | Many tahnks | |

As an addendum to Daves posting, please consider that: There is no such thing as no residue fluxing. A no-clean must herefore, have benign residues - in other words, they are not as efficient at removing surface oxides to enable good solder joints. S

Flux Designations and Composition

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from
